Like you implied in the other forum, I was thinking that the rear end is sprung a lot stiffer for big loads than I'll ever need. If I hit a bump or expansion joint, especially in a corner, its like the truck wants to do a little dance. It would be nice to get the rear planted a little better, but I'm not sure how much axle wrap that would cause. thx mike.
Leaf springs...yeah, I think I was considering that at one point, then instead, I bought a set of OE rear axle block for an '08+ because they're about 1-1/4" VS 2-1/2". The whole idea was to level truck without cranking the bars so much. I ended-up doing neither and the blocks are for sale now.
