Looong Shackles Dont Do It! You Wont Be Happy with the Results, Instead Look at the Tech Articles and add a leaf from the boneyard ( cheap) or Replace the Springs. Long Shackles Change the Pinion Angle and Allow More Side Movement (read crappy Handling)
Yes, I did this for a short time, and got rid of them quickly. I now have the 4-leaf springs, and a 1" lift block out back to get the hips up high enough to clear my meats. Or maybe I used the blocks to lower it an inch. I don't remember now. I would have to go out and look. Either way, use blocks rather than longer shackles.
You could also just lower the front instead of raising the back, and it would cost virtually nothing. In any case, never put those stupid shackles on , The only thing worse than that (on Mavericks/Comets) is air shocks).
