2003–2024 Toyota 4Runner, FJ Cruiser, GX
The RCI Offroad Transmission Skid Plate protects the transmission, second cross-member, and third cross-member on 2003–2024 Toyota 4Runner, FJ Cruiser, and GX models. Underbody strikes on rough terrain or rocky approaches can crack or damage your transmission—a repair that can exceed $3,000. This skid plate fills the gap left by weak OEM protection and installs with service openings for maintenance access without removal.
Steel or Aluminum Protection for Your Transmission
Choose between laser-cut 3/16" steel or 1/4" aluminum depending on your weight and durability priorities. Both options are custom-fit to your generation and integrate seamlessly with RCI front and transfer-case skid plates, or work as a standalone upgrade to your undercarriage armor.
- Dual Material Options: Select 3/16" steel for maximum impact absorption or 1/4" aluminum for reduced unsprung weight—both laser-cut for precise fitment.
- Full Transmission Coverage: Protects the transmission pan, second cross-member, and third cross-member—areas OEM skid plates often leave exposed.
- Service Openings: Access your transmission for fluid checks and service without unbolting the entire plate.
- Modular Design: Pairs with RCI front and transfer-case skid plates for a complete underbody system or installs independently.
- Custom Fit: Built specifically for 2003–2024 4Runner (including 4th and 5th generations), FJ Cruiser, and GX models.

Do all 4Runners have skid plates?
?
No. 4Runners from 2003 onward come with OEM underbody protection, but factory skid plates are often thin and do not provide full coverage over the transmission. Many owners upgrade to aftermarket skid plates like the RCI Offroad transmission plate for better protection in high-impact areas.
Does 4Runner TRD Off-Road have skid plates?
Yes. The TRD Off-Road package includes factory skid plate protection, but OEM plates are lightweight and leave the transmission area partially exposed. Many TRD Off-Road owners add a dedicated transmission skid plate for additional protection on technical terrain.
Are skid plates necessary?
Skid plates are not required for street driving but are essential if you regularly approach steep terrain, rock crawl, or drive unprepared trails where undercarriage strikes are likely. A single impact to your transmission can cost $3,000+; skid plates are cheap insurance by comparison.
How to install TRD skid plate 4Runner?
Refer to the installation instructions included with your specific skid plate, as mounting points and fastener locations vary by generation (4th vs. 5th gen) and material (steel vs. aluminum). Most bolt to existing frame points and require basic hand tools; refer to fitment guide for vehicle-specific steps.
What is the purpose of skid plate?
A skid plate shields vulnerable undercarriage components—such as the transmission, transfer case, fuel tank, and cross-members—from rock strikes, stumps, and terrain contact. It distributes impact load across a larger area and deflects obstacles, preventing costly damage and keeping your 4Runner trail-ready.

Bolted right on and fit perfectly. Support even confirmed fitment before I ordered.
Finally a shop that actually knows Toyotas. No guesswork, no wrong parts.
Fast shipping and the install guide made it a one-evening job. Stoked.
