FITMENT INFORMATION

• Toyota Tundra 3rd Gen Hybrid (2022, 2023, 2024, 2025, 2026) 3.4L Twin-Turbo V6 i-FORCE MAX

FITMENT NOTE

This V2 Cat Shield fits hybrid Tundras only. It is designed around the factory catalytic converters and factory suspension configuration. Confirm your truck still has its original converters and that suspension modifications have not changed the protected area before ordering.

V2 OR V1: THE DIFFERENCE THAT MATTERS

The V2 is a bank-specific catalytic converter shield that intentionally leaves the transmission area uncovered, making transmission-fluid service easier. It is the right choice if you want targeted converter protection without a full skid-plate design. If complete transmission coverage is important for your build, choose the Miller CAT V1 Cat Shield instead.

PRODUCT DESCRIPTION

The 3rd Gen Tundra Hybrid puts i-FORCE MAX power under the hood, but the catalytic converter area is still exposed below the truck. Miller CAT designed this V2 Cat Shield as a targeted deterrent for that area, using a vehicle-specific panel and tamper-resistant hardware instead of a universal cover that needs to be adapted to fit.

Its design makes the tradeoff clear. The V2 protects the converter bank while leaving the transmission uncovered for easier fluid service. That works well for an owner who wants a straightforward, no-drill shield without adding full transmission coverage. Choose aluminum to keep weight down, or 12-gauge stainless steel for a heavier-gauge material option.

Like any catalytic converter shield, it is intended to make unauthorized removal more difficult. It cannot guarantee that theft will not occur.

MILLER CAT WARRANTY

Miller CAT provides a 90-day limited warranty against manufacturer defects that prevent proper installation or function. Warranty coverage applies to the original purchaser with proof of purchase from an authorized retailer.

Raw aluminum and stainless-steel panels may show scratches, oxidation, residue, or cosmetic marks from manufacturing and shipping. These normal material characteristics are not considered defects. Damage related to incorrect installation, road debris, modifications, labor, diagnostic charges, or incidental costs is not covered.

ABOUT MILLER CAT

FITMENT INFORMATION

• Toyota Sequoia 3rd Gen Hybrid (2023, 2024, 2025, 2026) 3.4L twin-turbo V6

FITMENT NOTE

• Fits Sequoia Hybrid models only.
• Designed for vehicles with original factory catalytic converters and no suspension modifications that affect underbody fitment.
• Professional installation is recommended by Miller CAT.

V2 OR V1: THE DIFFERENCE THAT MATTERS

The V2 Cat Shield is a bank-specific design that protects the catalytic converter area while intentionally leaving the transmission uncovered. That gives you easier access for transmission-fluid service and avoids the full skid-plate-style coverage of the V1.

Choose the V2 if converter-theft deterrence and easier transmission access are the priority. If you specifically want transmission coverage as part of the shield design, Miller CAT's V1 Cat Shield is the better match.

PRODUCT DESCRIPTION

The Sequoia is built for hauling people, gear, and trailers, but the hybrid catalytic converter area is still accessible from underneath. The Miller CAT V2 Cat Shield adds a vehicle-specific barrier and tamper-proof hardware without turning the entire transmission area into a covered skid plate.

That distinction is the reason to buy the V2. It is for the Sequoia owner who wants a direct-fit catalytic converter theft deterrent but does not want to remove a full-coverage shield when transmission-fluid service comes around. Choose aluminum or 12-gauge stainless steel, then install it without drilling into the truck.

THEFT DETERRENCE, NOT THEFT PROOF

A Cat Shield adds time, noise, and difficulty to catalytic converter access. It is a theft deterrent, not a guarantee that a determined thief cannot remove the converter with enough time and tools.

MILLER CAT WARRANTY

Miller CAT provides a 90-day manufacturer warranty against defects that prevent proper installation or function. The aluminum and stainless steel panels are raw, unpainted materials. Mill marks, light scratches, oxidation, and manufacturing residue are normal and are not considered defects.

PRODUCT DESCRIPTION

The FJ Cruiser's ride height is part of what makes it useful off pavement, but it also leaves more room for someone to get underneath it. The Miller CAT Cat Shield covers the catalytic converter area with a vehicle-specific panel and tamper-proof hardware, making a quick theft attempt much harder to pull off.

This is a direct-fit, drill-free kit made for the 2007-2014 FJ Cruiser. Choose aluminum, 16-gauge stainless steel, or 12-gauge stainless steel based on the material you want under your truck. Each version uses the same Standard FJ Cruiser fitment and includes the hardware needed for installation.

THEFT DETERRENCE, NOT THEFT PROOF

A Cat Shield adds time, noise, and difficulty to catalytic converter access. It is a theft deterrent, not a guarantee that a determined thief cannot remove the converter with enough time and tools.

WHAT TO KNOW BEFORE INSTALLING

This is not an all-purpose skid plate. It is purpose-built to cover the GX 550’s catalytic converter area and make a quick theft attempt much more difficult.

Routine engine oil changes can be completed with the shield in place. Transmission service is different: Miller CAT specifies that the shield needs partial removal for that work. If you handle your own maintenance, that is worth knowing before installation.

It is also important to set the right expectation. The Cat Shield is a theft deterrent, not an absolute theft-proof device. It adds time, noise, and a major obstacle for someone trying to access the converters underneath your GX.

PRODUCT DESCRIPTION

The GX 550 is built for getting farther from pavement, but its catalytic converters still sit in a place that can be reached from underneath. The Miller CAT Cat Shield puts a vehicle-specific aluminum barrier between those components and a saw blade.

Rather than drilling into the truck or adapting a universal panel, this kit bolts to the GX 550 using application-specific mounting points and tamper-proof screws. It is a practical protection upgrade for a daily-driven GX, an overland build that spends nights away from home, or any owner who wants to make the underside of the truck less inviting to a thief.

MILLER CAT WARRANTY

Miller CAT provides a 90-day manufacturer warranty against defects that prevent proper installation or function. The raw aluminum shield may have mill marks, light scratches, oxidation, or manufacturing residue. These are normal material characteristics and are not covered as defects.

PRODUCT DESCRIPTION

The Miller CAT Cat Shield is a vehicle-specific aluminum barrier for the catalytic converter on a 4th Gen Tacoma Hybrid. It bolts into place without drilling and uses tamper-proof fasteners that make access to the converter more difficult and more time-consuming.

It is built around the factory Tacoma Hybrid underbody, so it keeps the converter covered while still allowing normal engine and transmission oil service without removing the shield. The kit includes the security hardware, key, protected-vehicle sticker, and installation instructions.

THEFT DETERRENCE, NOT THEFT PROOF

A Cat Shield is designed to significantly increase the difficulty of catalytic converter theft. It cannot guarantee that theft will be impossible if a determined thief has enough time and tools.

MILLER CAT WARRANTY

Miller CAT provides a 90-day manufacturer warranty against defects that prevent proper installation or function. The warranty does not cover surface marks, scratches, oxidation, manufacturing residue, improper installation, road debris, modifications, labor, diagnostics, or incidental costs.

Fitment Note

Fits 2025-2026 6th Gen Toyota 4Runner, non-hybrid. For the hybrid powertrain, use the 4Runner Hybrid-specific Cat Shield instead. Requires the original factory catalytic converter with no suspension modifications for Miller CAT's fitment guarantee to apply.

Product Specs & Install Notes

• Complete bolt-on installation, no drilling required
• Durable aluminum construction, designed and manufactured in the USA for this specific vehicle
• Every cutout and mounting point matches the factory layout for a clean, secure fit
• Secured with patented tamper-proof security screws, each with a unique key
• Allows for easy engine and transmission oil changes, no shield removal needed
• 90-day manufacturer's warranty against installation or performance defects

The new 6th gen 4Runner is a real target, converters are a top pick for thieves because of the precious metals inside, and a stock underbody doesn't slow them down at all. This shield bolts straight to the factory mounting points, no drilling, no cutting, and it won't touch your factory warranty.

This won't get in the way of an oil change. Some owners will need it off for a transmission fluid service, so check your 4Runner's maintenance schedule for that interval.

Being straight with you here: this is a deterrent, not a promise. It makes the job slow and loud enough that most thieves move on, but a determined thief with enough time could still beat it. Still much better odds than leaving it wide open. For full underbody coverage, this pairs with Miller CAT's MCX Skid Plate for the same 4Runner.

FITMENT NOTE

This is the Miller CAT V1 Cat Shield for hybrid Tundras only. It requires the original factory catalytic converter and a factory-style suspension configuration for Miller CAT's fitment guarantee to apply. It does not fit non-hybrid Tundra models.

V1 VS. V2

The V1 is the larger aluminum shield and provides coverage over the transmission area in addition to the catalytic converter area. Choose this version if full transmission coverage is part of your priority. Miller CAT's V2 is a smaller, bank-specific design that leaves the transmission uncovered for easier transmission-fluid service.

  • Detailed installation guide

PRODUCT DESCRIPTION

The hybrid Tundra has a lot going for it, but the catalytic converter area remains accessible from below. The Miller CAT V1 is the version to choose when you want more than a small converter-only panel. Its larger aluminum design also covers the transmission area, giving the underside a more complete layer of protection than the V2.

It mounts to the truck without drilling and uses vehicle-specific mounting points rather than a universal layout. Miller CAT includes tamper-resistant security hardware with unique key patterns, making the shield more difficult and time-consuming to remove without authorization.

This is a theft deterrent, not a guarantee against theft. It is designed to make converter removal more difficult, but a determined thief with sufficient time and tools can still cause damage or remove components.

MAINTENANCE CONSIDERATIONS

The shield does not interfere with engine oil changes. Depending on the service being performed, removal may be required for transmission-fluid service. Keep the supplied hardware key with your truck records so it is available when service is needed.

MILLER CAT WARRANTY

Miller CAT provides a 90-day limited warranty against manufacturer defects that prevent proper installation or function. Warranty coverage applies to the original purchaser with proof of purchase from an authorized retailer.

Because this is an underbody component, surface scratches, oxidation, residue, and cosmetic marks from manufacturing, shipping, or normal road use are not considered defects. Damage caused by incorrect installation, vehicle modifications, road debris, labor, diagnostics, or incidental costs is not covered.

Hybrids get targeted more than most, the converters carry more precious metal, and thieves know it. This shield bolts straight to the factory mounting points on the Land Cruiser Hybrid, no drilling, no cutting, and it won't touch your factory warranty.

One real owner's review sums up the appeal well: it's a straightforward deterrent for anyone who's already had a converter stolen once and doesn't want to go through that again. Install ran a little over an hour for one self-installer working in the garage, no lift required, though it was described as a tight squeeze under this particular platform, budget a bit of patience.

This won't get in the way of an oil change. Some owners will need it off for a transmission fluid service, so check your Land Cruiser's maintenance schedule for that interval.

Hybrids get targeted more than most, the converters carry more precious metal, and thieves know it. This shield bolts straight to the factory mounting points on your 4Runner Hybrid, no drilling, no cutting, and it won't touch your factory warranty.

Real installs from actual owners are running well under an hour and a half, most doing it themselves in the garage without even needing a lift. Instructions are clear enough for a first-timer, though a couple of owners mentioned the photos could stand to be zoomed out a bit for clarity, keep that in mind and take your time matching up mounting points if it's your first go at something like this.

This won't get in the way of an oil change. Some owners will need it off for a transmission fluid service, so check your 4Runner Hybrid's maintenance schedule for that interval.

• 2025 Toyota Tacoma 2.4L (4th Gen, N400)

Fitment Note

Fits 2024-2025 4th Gen Toyota Tacoma 2.4L, hybrid or non-hybrid. Some installs may need eight additional OEM control arm hole plugs (Toyota Part 90950-A1021) to prevent wind noise, not included with this skid plate.

Product Specs & Install Notes

• 12-gauge 304 stainless steel construction
• 34 lbs, light for the coverage you're getting
• Resists corrosion, no touch-up paint or maintenance needed
• Service windows built in for quick oil filter and drain plug access
• Tamper-proof hardware kit and install guide included

The 4th gen Tacoma's 2.4L turbo hangs low up front, right where rocks and trail debris hit first. This plate is 304 stainless, the kind that takes the hit and keeps going without you ever needing to touch up the finish. At 34 lbs it's not adding real weight to your build, and the built-in service windows mean you're not pulling the whole plate every time you're due for an oil change.

Worth knowing before you install: some trucks whistle at speed once the control arm holes are exposed. If yours does, eight OEM plugs (Toyota Part 90950-A1021) close that up, they're not included here, so grab them ahead of time if you'd rather solve it in the same afternoon as the install.

For full coverage front to back, this pairs with Miller CAT's Cat Shield for the same Tacoma, available for both hybrid and non-hybrid models.

Fitment Note

Fits all 2024-2026 8th Gen Toyota Land Cruiser Hybrid trims, this generation is hybrid-only in the US market. Designed specifically for this platform, not a shared or adapted fitment.

Product Specs & Install Notes

• Lightweight, corrosion-resistant construction, just 34 lbs
• No touch-up or maintenance needed to resist rust
• Service windows built in for quick oil filter and drain plug access
• Complete bolt-on installation
• Won't interfere with oil changes

The new Land Cruiser is built to go places, and this skid plate is built to take the hit when it does. It shields the underbody from rocks and trail debris without piling on weight, 34 lbs is light for the coverage you're getting, and the corrosion resistance means you're not chasing rust spots down the road.

Miller CAT built in real service windows, so you're not pulling the whole plate every time you need the oil filter or drain plug. It won't get in the way of oil changes. Transmission fluid service is the one exception, some owners will need to pull the plate for that, so check your Land Cruiser's specific maintenance interval and plan around it.

One honest note from a verified buyer: install takes a bit of patience getting every hole lined up, and at least one owner noticed their plate sitting very slightly off after install, worth double-checking your alignment as you go rather than rushing the last few bolts.

For full underbody coverage, this pairs with Miller CAT's Cat Shield for the same Land Cruiser, together they cover both the converter and the rest of the vulnerable underside.

Will not fit alongside lift kits that modify or replace the stock chassis crossmember. Assumes your truck still has the factory Radiator Support Splash Shield installed (Toyota part 51406-04020). This is the RWD-specific shield, not interchangeable with the 4WD version, order the correct drivetrain variant for your truck.

Product Specs & Install Notes

• Complete bolt-on installation, no drilling required
• Designed and manufactured in the USA to fit this specific truck and drivetrain
• Part of Toyota's Associated Accessory Product line
• Secured with patented tamper-proof security screws, each with a unique key
• Two material options: Aluminum or 16 gauge Stainless Steel (see variants below)
• Raw, unfinished metal, mill marks and light surface oxidation are normal, not a defect
• Kit includes shield, hardware, security key, Cat Shield Protected sticker, and install guide
• 90-day manufacturer's warranty against installation or performance defects

Aluminum (SKU TOY-043) — $230.00, the lighter and more budget-friendly of the two options, still fully bolt-on with the same tamper-proof hardware.

Stainless Steel 16 Gauge (SKU TOY-014) — $320.00, heavier duty and more resistant to being cut or pried, the pick if you're in a high-theft area or just want the extra peace of mind.

Catalytic converter theft is a real problem on this generation Tacoma. High ground clearance and an exposed underbody make it an easy target, and this shield bolts straight to the factory frame points, no drilling or permanent modification, so your factory warranty stays intact. Tools needed for install are a 1/4" bit driver and a 12mm socket, most owners get it done themselves in under an hour with a jack and stand.

This shield will not interfere with oil changes. Some owners will need to remove it for a transmission fluid service depending on your maintenance interval, Toyota recommends 30,000-60,000 miles for that on most of these trucks, check your specific schedule. It also will not cause the converter to run hot or trap heat, Miller CAT manufactures converters themselves in addition to shields, so the shield is designed with proper clearance in mind.

Worth being upfront about: this is a deterrent, not a guarantee. It significantly raises the time and tools needed to steal the converter, which is usually enough to send thieves elsewhere, but a determined thief with enough time could still defeat it. Miller CAT backs this up with real theft-attempt video evidence on their site if you want to see it in action.
