got the deaver leaf springs. f 31's. I love them. they ride so awesome. I should have bought them a long time ago. I would recommend them to anyone. ive only had them in for a week now but they hold my spare and toolbox just fine without sagging at all. with the hanger flipped with stock shackle and the block on the rearend removed mine sits almost exactly the same height as it did with the stock leafs. my truck has 223,000 miles on it so I'm sure the stock leafs were settled down from new. the stock hanger does not hit the box without a body lift. someone said it would rub. it doesn't. I redrilled the hole in my stock shackle an inch below the original one to give myself an inch lift in the back. had to do some grinding so the leaf wouldn't rub when the shackle rotates. I think I'm still gonna look for a aftermarket shackle that's an inch shorter than the stock one. I think camburg makes one. not positive though. after I did the coilover conversion in the front it sat noticeably higher than the back until I raised it an inch. I need to take some pics and get them on here.
