Description

RCI Offroad Catalytic Guards | 2024+ Tacoma & 2003+ 4Runner / FJ / GX

Stop Theft in Seconds. Heavy-Duty Underbody Protection. 100% Made in the USA.

The Ultimate Shield Against Theft and Trails

The RCI Offroad Catalytic Guard Kit is your first line of defense against the rising epidemic of catalytic converter theft and costly underbody damage. Whether you are navigating tight technical trails or parking in the city, your vehicle’s most vulnerable components are now protected.

Engineered to provide full coverage, these guards fill the exposed gaps between your vehicle frame and the transmission skid plate. Available in 1/4" 5052 Aluminum for legacy models and 12-Gauge Steel for the newest generations, RCI ensures a precision fit with a premium finish that outlasts the elements.

The Problem & The Solution:

The Pain: Catalytic converter theft takes less than 60 seconds and can cost over $3,000 in repairs and weeks of downtime.
The RCI Solution: A seamless, vented armor system that blocks access to thieves while providing a smooth, flat surface to slide over off-road obstacles.

Real Owner Feedback ★★★★★

"After my neighbor lost his cats to a thief in broad daylight, I ordered the RCI guards. The fitment with my RCI transmission skid was perfect. They are solid, don't rattle, and give me huge peace of mind when parking at trailheads or in the city. Truly a 'must-have' mod for any 4Runner owner."

- Mark S., 5th Gen 4Runner Owner
Important Compatibility Note

Required Part: This kit REQUIRES an RCI Transmission Skid Plate for installation. These guards are designed to bolt directly to the RCI skid plate to create a complete barrier. They will not function as a standalone product.

Frequently Asked Questions

+ Do these guards require drilling for installation?

The guards are a direct bolt-on addition to the current RCI Transmission skid plate. However, if you purchased your transmission skid plate several years ago (prior to catalytic guards being offered), minor drilling into the skid plate flange may be required.

+ Will these fit with other brands of skid plates?

These are specifically designed to work with RCI Transmission Skid Plates. They may be compatible with others with modification, but we only guarantee fitment with RCI and the Toyota TRD PRO engine skid plate.

+ Why the difference in material (Steel vs. Aluminum)?

For the 4Runner/FJ/GX models, we use 1/4" Aluminum to provide heavy-duty protection without excessive weight. For the 2024+ Tacoma and 6th Gen 4Runner, we use 12-gauge steel with a high-durability powder coat to match the specific structural requirements and frame geometry of the newer chassis.

+ Will these cause my vehicle to run hotter?

No. RCI guards feature a vented design specifically engineered to ensure adequate airflow and heat dissipation for your exhaust system and transmission.

+ How long does the installation take?

Most users report an installation time of 20-30 minutes using basic hand tools, provided the RCI Transmission Skid Plate is already installed on the vehicle.

Prop 65

California Residents

Prop 65 Warning- Product may contain chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. For more information, go to www.P65Warnings.ca.gov

Proposition 65 is a California law passed in 1986. Its goals are to protect drinking water sources from toxic substances that may cause cancer and birth defects and to reduce or eliminate exposures to those chemicals generally, for example in consumer products, by requiring warnings in advance of those exposures.

The regulation requires the State of California to revise and republish yearly a list of chemicals known to the State of California to cause cancer or birth defects or other reproductive harm. The current list contains over 900 naturally occurring and synthetic chemicals. This regulation also requires manufacturers to place warnings on products that contain any of the chemicals listed by the State of California. No other states require warnings of this nature, and products with Prop 65 warning language are legal to sell in all states. Detailed information regarding requirements for compliance to the California Prop. 65 is can be found at: www.P65Warning.ca.gov
