I've got a 91 f-150 short box standard cab, and I'm putting a 6" superlift lift kit on it. It came with 4.5" blocks for the rear but I got superlifts 4.5" leaf springs from bronco graveyard to put in instead of the blocks. I've got them in and everything I measure shows only 2.5" of lift.. I called superlift and the guy says there within specs and they are the right part number. I'm wondering if anyone with a 6" lift (4.5" in the rear) could give me a measurement from the center of the axle to the fender.
And yes the factory blocks are in. Everyone likes to ask that more than once, im not that stupid. Thanks!

 

i got 8ins of lift but take away 2in and i measures 28inchs but i put the 4.5in blocks on and the one i got had another leave spring

 

where at in sc you from

 

i think what happens is that when u buy thre kit there compinsating t make the truck level a.k.a diesel look so you know how our f-series have that nasty rake there just makin up for the front also ive found those block measurements are always way off.

 

Yea, I know a 6" lift only lifts the front 6, and then brings the back up level. But the truck sits like a homo lowrider with the back end way down. I called Superlift and BG and they both said the springs are right and they dont know why its messed up. But I just put 4" blocks in and took out the stock 2" ones, so it sits fine now.
I just dont know why the springs only show 2 1/2" of lift..
