2003-2009 Toyota 4Runner (4th & 5th Gen)
The RCI Offroad Fuel Tank Skid Plate protects the fuel tank on 2003–2009 Toyota 4Runner (4th and 5th Generation), where the factory fuel tank sits dangerously low and vulnerable to trail hazards, rock strikes, and high-center damage. This plate is your first line of defense against expensive fuel system repairs on the trail or street.
Underbody Protection Built for 4Runner Abuse
The 4Runner's fuel tank hangs low enough to catch rocks, roots, and obstacles that would otherwise puncture or rupture a critical component. RCI's skid plate transfers impact loads to the frame, keeping your fuel system intact whether you're daily driving or pushing technical terrain.
- Material Options: Choose laser-cut 3/16" steel for maximum impact resistance or 1/4" aluminum for a lighter weight alternative—both custom-fitted to the 4th and 5th Gen 4Runner fuel tank geometry.
- 1/4" Aluminum Construction: Rust and corrosion resistant, requires no finish treatment prior to installation, substantially stronger than factory skid plates, and reduces unsprung weight compared to steel.
- Heavy-Duty 3/16" Steel Option: Maximum protection for serious trail use and rock crawling; engineered to absorb direct impacts that would breach aluminum.
- Precision Fit: Custom-shaped for all 4th and 5th Gen 4Runners, as well as GX470 and GX460 Lexus models, ensuring zero gap between plate and fuel tank.
- Professional Quality Finish: Laser-cut edges and frame attachment points meet OEM standards for alignment, clearance, and bolt torque specifications.
Fitment: 2003–2009 Toyota 4Runner (4th & 5th Generation)

It also fits GX470 and GX460 Lexus variants with identical underbody geometry. Use the fitment verifier above to confirm compatibility with your exact configuration.

do all 4runners have skid plates
?
No. Factory 4Runners do not come equipped with fuel tank skid plates as standard equipment. Toyota's undercarriage protection is minimal on the fuel tank, which is why aftermarket protection like the RCI plate is necessary for serious off-road use.
does 4runner trd off road have skid plates
No. Even TRD Off-Road trim levels do not include factory fuel tank skid plates. TRD packages add off-road suspension and all-terrain tires, but the fuel tank remains unprotected—making an aftermarket skid plate essential for rock crawling and technical terrain.
are skid plates necessary
Yes, on 4Runners. The factory fuel tank sits extremely low and is vulnerable to puncture from rocks, roots, and trail obstacles. A skid plate prevents catastrophic fuel system damage and repairs that can exceed $1,000. If you drive off-road at all, protection is mandatory.
how to install trd skid plate 4runner
Refer to the RCI Offroad installation guide for your specific year and material option. Installation typically involves raising the vehicle, removing the factory splash guard (if present), positioning the skid plate, and bolting it directly to the frame using supplied hardware. Professional installation is recommended if you lack underbody access or frame bolt familiarity.
what is the purpose of skid plate
A skid plate is a protective barrier between the fuel tank and trail hazards. It distributes impact loads across a larger area and transfers them to the frame rather than concentrating them on the fuel tank itself, preventing ruptures, leaks, and expensive repairs from rock strikes, high-centering, and debris contact.
Built by Owners, for Owners
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.
