Note: If the optional 162-Stinger was purchased install it by first co mpletel y drilling out the holes in the center tube of the bumper, there are holes in the backside of the tube you just need to drill them all the way through. Male sure that you drill straight inline through the bumper; start with a small drill bit and then gradually work your wayto larger sized drill bits. Then line up stingers threaded mounting points with the bottom holes that are next to the frame rails on the bumper mounting brackets and sliding the thr eaded stud into those holes and securing with 1/2" fl at washer and 1/2" Nyi ocknut. Do not full ytighten these bolts. Install 1/2" X 21/2" hex head bolts with lock washer and flat washer through front bumper and into the stinger where the threaded mounts are welded into place. Tighten all nuts and bolts at this ti me. If you cannot get all the bolts into place you may want to enlarge the hol es wher e the 2 '/2" long bolts install through. We rec om me nd that you paint all bare metal with r ust pr evention paint. If you have the Rubicon black finish we recommend that you use rustol eum textured bl ackpaint for touch-ups and for our gloss black, a black fingernail polish or automotive gloss blackspr ay paint will wor kthe best.
Step 2. Slide your new bumper over the vehicle frame and line up the mounting holes in the bumper with the mounting holes i n the frame. See photos 3 &4. On TJ & LJ wranglers, the bumper will bolt to the top 2 mounting holes on the frame and one on the bottom of the frame on each frame rail. On YJ wranglers, the bun-per will bolt to one hole on the top and one hol e on the bottom of the frame rail. You will re-use your OEM bumper mounting bolts on both model Wranglers.
Step 3. Secure bumper using the Tor x bit bolts you removed in step 1. See photo 4. Photo 4 shows mounting on a TJ&LJ Wrangler, mounting on an YJ Wrangler will be different then photo 4.
Step 4. After 500 miles or first off-road trip, re-checktightness on all nuts and bolts.
