2003-2009 Toyota 4Runner (4th Gen)
The RCI Offroad Transfer Case Skid Plate for 2003-2009 Toyota 4Runner (4th Gen) protects your transfer case, third cross-member, and exhaust pipe from trail hazards and underbody damage. Unlike the OEM skid plate—which bolts to the transfer case itself and disperses impact poorly—this RCI plate mounts to the frame, absorbing and redirecting impact energy away from critical drivetrain components.
Transfer Case Protection Built Tough
The 4th Gen 4Runner's OEM skid plate is lightweight and inadequate for serious off-road use. This RCI Offroad replacement addresses that weakness with frame-mounted construction that keeps impact force away from your transfer case and exhaust system.
- Material Options: Choose 3/16" CNC laser-cut steel for maximum durability or 1/4" laser-cut aluminum for a lighter-weight alternative without sacrificing protection.
- Full Underbody Coverage: Protects the transfer case, third cross-member, and exhaust pipe—the three most vulnerable points in the 4Runner's undercarriage.
- Frame-Mounted Design: Bolts to the frame rather than the transfer case, ensuring impact energy disperses through the chassis instead of translating directly to your drivetrain.
- Custom Fit: CNC laser-cut for 2003-2009 4Runners—no trimming, no modification of the plate itself. Refer to the fitment guide for any vehicle-specific installation notes.
- Premium Finish: Each plate is finished to RCI's exacting standards, ensuring corrosion resistance and long-term durability in harsh trail and weather conditions.
Fitment: 2003–2009 Toyota 4Runner (4th Generation)
This skid plate is engineered specifically for all 4th generation 4Runners produced between 2003 and 2009, regardless of trim level or drive configuration. Fits all cab and body styles within this generation. Use the fitment verifier above to confirm compatibility with your exact configuration.

Do all 4Runners have skid plates?
?
No. 4th generation 4Runners (2003–2009) come equipped with an OEM skid plate, but it is lightweight and bolts directly to the transfer case rather than the frame. Older and newer generations have varying levels of underbody protection, and many lack adequate transfer case coverage. Always verify your model year and factory equipment before assuming protection is adequate.
Does 4Runner TRD Off Road have skid plates?
Yes. TRD Off Road 4Runners include an OEM skid plate, but it is insufficient for serious off-road use. The factory plate mounts to the transfer case itself, which means impact energy transfers directly to drivetrain components rather than dispersing through the frame. An aftermarket frame-mounted plate like the RCI Offroad design provides superior protection.
Are skid plates necessary?
Yes, for any 4Runner that sees regular off-road use or rocky terrain. Skid plates protect the transfer case, oil pan, and exhaust system from impacts that can cause fluid leaks, mechanical failure, or loss of power. On-road only? Less critical. On the trail? Essential.
How to install TRD skid plate 4Runner?
Installation requires removing the OEM skid plate (if present), positioning the new plate, and bolting it to the frame at designated mounting points. The process typically involves hand tools and a lift or ramps. Refer to the RCI Offroad installation guide included with your plate. If you are unfamiliar with underbody work, have a shop handle installation to ensure proper fitment and torque specifications.
What is the purpose of skid plate?
A skid plate shields vulnerable underbody components—transfer case, transmission pan, oil pan, and exhaust system—from rocks, logs, and terrain obstacles. It absorbs direct impacts and redirects force away from drivetrain components, preventing leaks, mechanical damage, and costly repairs. On the trail, a skid plate is the difference between a minor hit and a trip-ending failure.

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.
