2018 JL Front Bumper Installation

Published on 03/06/2018

Now that the stock bumper has been removed, it's now time to install your new Stealth Fighter Front Bumper. This install typically takes ~2 hours depending on experience and works best with two people. Let's get started!

1. **THIS STEP IS OPTIONAL** Cut the frame stilts just below the sway bar mounts. Follow the line shown in (Fig E). Make sure to paint over any bare metal when you are finished cutting.

2. If you have any lights or a winch to install on your bumper, now is a good time to do so. Please follow the light/winch manufacturer's guide for mounting/wiring information.

3. Set the supplied U-Nuts (x6) in place on your new bumper. (Fig F)

5. Set the bumper into place on the vehicle. Install the supplied 3/8" Bolts (x6) and 3/8" Washers (x6) from the backside of the frame horns. Then, install the supplied 1/2" Bolts (x2), 1/2" Washers (x4), and 1/2" Lock Nuts (x2) into the outer/lower mounting holes. Leave these bolts loose for now. (Fig H)

7. Stand back and enjoy your new ADD Stealth Fighter Front Bumper.

8. Check and re-tighten, if needed, all mounting bolts after 100 miles and periodically thereafter.
