Rock Defense Rear Bumper
Arm your second-gen Toyota with this industry's premier trail protection: The Rock Defense Rear Bumper. Engineered specifically for the 6-lug 4WD 4Runner, this bumper is built for the driver who demands high-clearance performance without sacrificing structural integrity. Unlike standard mild-steel bumpers, the Rock Defense series is constructed from high-strength 1035 DOM tubing, providing a rigid shield against impacts that would otherwise crush your factory quarter panels and liftgate.
Performance Engineering for the 2nd Gen 4Runner
- DOM Tubing Construction: Built using 1.75" OD x .120" wall thickness 1035 DOM tubing. This provides a superior strength-to-weight ratio and increased dent resistance compared to standard electric-resistance welded (ERW) tubing.
- Integrated 2" Receiver: Features a built-in 2-inch hitch receiver, maintaining a sleek, tucked profile while providing a versatile mounting point for hitch-style accessories.
- Optimized Departure Angle: The high-clearance design is tucked tight to the body, allowing you to descend off ledges and rocks without the bumper "dragging" or hanging up on the terrain.
- Precision Chassis Mounting: Designed to bolt directly to the 4Runner's rear frame rails, ensuring that impact energy is distributed through the chassis rather than the body.
Key Features
- Rugged Minimalist Aesthetics: The aggressive tube-style design complements the classic lines of the 1990-1995 chassis while signaling a professional level of trail readiness.
- Corrosion Protection for Shipping: Each bumper is shipped unpainted and lightly oiled to ensure it arrives at your door free of surface rust and ready for your choice of paint or powder coat.
- Expandable Protection: For those tackling the most extreme terrain, this bumper is compatible with the Rear Bumper to Frame Support Kit (Part #: 3032410) for maximum structural reinforcement.
- Trail-Proven Durability: Specifically jigged for a consistent fit, ensuring a straightforward installation process that utilizes factory mounting locations.

Installation Instructions
-Note: Make sure bumper has been cleaned and oil is removed so the bumper can be painted before installation.
1. Align the bumper with the rear of the vehicle. Ensure all required mounting hardware is organized and within reach before beginning the installation.
2. Slide the bumper mounting brackets into the factory frame rail apertures. Ensure the mounting plates are fully seated against the frame for proper bolt alignment.
3. Assemble the washers onto the provided bolts and insert them through the aligned mounting holes. Maintain a loose fit at this stage to allow for final bumper leveling and adjustment.
4. Level and center the bumper for an even fit, then fully tighten all mounting hardware. Ensure the gap between the bumper and the body is uniform on both sides before securing the bolts.
