I bought a set that were supposed to be stock replacement plus 1" super cheap from Summit. They made my truck ride like a stink bug and were teeth rattling stiff. The only time it rode nice is when I carried a big load of block.

They didn't come with bushings and stock ones didn't fit. Have to get theirs. I found a bushing set in my junk pile that would work.

I ended up pulling two leafs before it rode right. I'm running 63" Chevs now.
