After work today I got the chance to throw on the rear shackles, turned out pretty good I got the 2 inches I figured I was going to get. I cranked in 2 inches on the front earlier and putting on the shackles was a breeze. To do this it requires that you use a 2 inch drop shackle for a C1500 Chevy truck. I couldn't stand the gold color shackles so I painted them black, and it didn't look good with the silver color of my truck.
1. Jack up the rear of the vehicle and support the FRAME with jackstands.
2. Lower the jack and pull it out. (Wheels should not touch the ground)
3. Remove the REAR shackle bolts (If you have a hitch, that will have to be removed first.)
4. Then the spring will actually go up. (You would think that it would drop down, but it doesn't)
5. Remove the stock rear spring shackle
6. Replace with the new shackle (It's actually a lowering shackle for a Chevy pick-up)
7. You will need a bottle jack or sissors jack for this step. Place the jack in between the frame and the leaf spring and raise it untill it comes down low enough to replace the rear spring shackle bolt. You will need to buy some washers for spacers because the shackles are slightly wider than the spring (required 4 flat washers each side).
8. Do the same thing to the other side and you're done! (with the rear)
9. Lower the rear and raise the front of the vehicle
10. With a large breaker bar tighten the torsion bar adjustment 8 equal turns. (mark your starting point) This will raise the front of the vehicle to match the rear.
11. Do that to both sides and lower the front.
12. Measure from the ground to he bottom of the fender (at the wheel) Make sure that distances are equal.
