1. Remove the skid plates, one covering the T-Case and one covering the automatic transmission if equipped.

3. Install the new crossmember skid plate, use 3 stock bolts removed from the
original skid plates.

4. Tighten the 3 factory cross member mounting bolts to 35 ft-Ibs.

5. Now is a good time to drill and tap the rear hole in the frame on the driver side and the gas tank skid plate tab for installation of the transfer case skid plate. This will allow for flush mounting hard- ware to be used.

6. You can now install the rear transfer case skid plate, install the skid plate on top of the
cross- member skid plate. If you drilled and tapped the gas tank and frame hole to %-20, use the supplied flat head allen bolts, if not us the original bolts, tighten to 35 ft-Ibs.

7. Install the 3 center %·20" flat head allen bolts with the flange nuts and tighten to 35 ft·lbs.

Attach the bottom of the bracket with a 3/8" bolt, washer and flange nut. Tighten the 3/8" bolt to 20 ft-lbs and then tighten the engine mount bolt to 45 ft-lbs.

9. Install the driver side frame brace to the frame bracket; the driver side is the shorter of the two. There is no top or bottom and can be installed in either direction. Use the supplied 3/8 bolts, flat washers and lock washers. Leave these bolts loose until all the other pieces are installed.

10. Install the front engine skid plate, put the rear on top of the crossmember skid plate and attach the front to the driver side frame brace. Using the W' flat head allen bolts and flange nuts, attach the rear of the engine skid to the front of the crossmember skid. Do not tighten these bolts yet; leave them loose until both of the front brackets are installed.
