Installation Steps
1
Remove Factory Bumper
Disconnect battery negative terminal. Remove plastic bumper cover and factory steel bumper assembly.
Save factory hardware - some bolts may be reused for new bumper installation.
Safety: Use jack stands to support vehicle. Never work under a vehicle supported only by a jack.
2
Prepare Frame Mounting Points
Clean frame rails where new bumper will mount. Remove any rust or debris.
Test fit brackets: Position mounting brackets on frame rails to verify alignment before final installation.
3
Install Mounting Brackets
Attach mounting brackets to frame rails using provided hardware. Hand-tighten bolts only at this stage.
Alignment is critical: Ensure brackets are level and properly positioned before tightening.
4
Position Bumper
With your helper, lift bumper and align with mounting brackets. Bumper weighs approximately 120 lbs - use proper lifting technique.
Center bumper: Equal spacing on driver and passenger sides. Check alignment from multiple angles.
5
Secure and Torque
Attach bumper to mounting brackets. Tighten all bolts in cross pattern.
Torque to specification: Follow manufacturer torque specs (typically 75-90 ft-lbs for frame bolts).
Critical: Proper torque is essential for safety. Under-tightened bolts can fail in off-road or recovery situations.
6
Install Accessories (Optional)
Winch installation: If installing winch, mount to bumper winch plate before final tightening.
D-rings: Install D-ring shackles in provided mounting points.
Lights: Mount LED light bar or fog lights if equipped. Route wiring carefully and secure.
7
Final Check
Verify all bolts are torqued. Check bumper alignment and clearances.
Test accessories: If winch or lights installed, test operation before first use.
Reconnect battery and test all vehicle systems.
