I removed three from the bottom of mine on the front and three from the rear. I installed aluminum blocks in place of the leafs to keep the ride higth the same. It helped some, but not much.
What did help mine was adding Poly-Slide to the leafs. Its a plastic liner that goes between each leaf to let them slide and move around. I got it from Speedway Motors. You will need to smooth up each leaf with a grinder or sander so they don't cut into it. I would change the u-bolts while you have it apart, they are cheap and its good insurance. Check with your local spring shop for u-bolts and center bolts. Joe
