My installation on a stock 97 TJ met several complications which lengthened install time. Some of these were rusted/broken bolts, stripped shocks and stripped T55 head bolt. To solve these issues I also used a cordless sawzall, 1/4” drill bit and cordless drill. I also purchased grade 8 SAE bolts and nuts at Ace hardware to replace broken bolts, etc.

Installation Instructions:

1. Park vehicle on flat surface. Set parking brake. Chock rear wheels. Loosen lug nuts on tires. Raise front of vehicle. (On front shocks and spacers, install one wheel at a time). Place jack stand under frame. Remove front wheel.

2. From either inside the engine compartment using long 15mm or 9/16” socket (depending on nut size), or inside the wheel well using a 15mm or 9/16” wrench, remove the upper stud nut from the front shock. (I had a complication here with my shocks being too worn. I used a sawzall with metal blade to cut the stud and nut)

3. Remove lower shock bolts using 13mm socket and wrench. Save this hardware for later use. 

4. Place a floor jack under axle to support axle. Remove the lower sway bar links from the axle. (this allows axle to be lowered) Use a 18mm wrench or socket and a T55 torx head. (I had one stripped had to drill out and replace bolt).

5. Use a 13mm socket to remove the coil spring clip, on the bottom of the coil. Lower the axle and remove the spring.

7. Install the new space with the stock spring isolator between it and the coil. Replace bump stop cup and rubber bump stop. ( I found using some dish soap helped with rubber stop going back in). Reinstall coil. Reinstall coil spring clip using 13 mm socket.

8. Install new shock using 13mm socket and wrench for bottom mounts and 9/16” wrench or socket for upper stud nut.

10. Torgque all bolts to factory specifications. Reinstall wheel. Remove jack stand and repeat on second front side.

11. For Rear Installation, both wheels are done at the same time. Chock front wheels. Loosen lug nuts on both wheels. Raise back of vehicle and place jack stands under the frame. Remove rear wheels. Place jack under differential to lightly support the axle.

12. Remove shock absorbers first. Lower mount use a 18 mm and 15 mm socket or wrench. Save bolts for later use. Use a 13 mm socket to remove upper bolts. (I broke two of these off and had to drill out and replace)

13. Remove the sway bar links using a 15 mm wrench or socket. Retain bolts.

14. Carefully lower axle. Watch axle vent tube. Remove coil springs. (you may need to use a spring compressor to remove and replace springs. I was able to remove them no problem and replace using the clockwise rotation of the coil and a pry bar)

15. Use a hammer or pliers to remove rubber bump stop. Use a 15mm socket to remove bump stop cup. Throw 15mm bolt away. Using the supplied 17mm bolt, install the spacer, coil spring isolator and bump stop cup.
