Protect your vehicle’s most vulnerable components with the ARB Under Vehicle Protection Skid Plate—built for off-road confidence on Toyota 4Runner and FJ Cruiser models without KDSS.
While bumpers and sliders defend visible panels, serious trail damage often occurs underneath the vehicle. ARB’s skid plate system is designed to shield critical underbody components from rocks, ledges, and unexpected obstacles encountered during off-road driving.
Constructed from 3mm laser-cut, pressed, and folded steel, this skid plate offers an excellent strength-to-weight ratio while maintaining high impact resistance. The chassis-mounted design ensures outstanding structural integrity and dependable protection for vital components including the steering system, oil pan, transmission, and transfer case.
