02 F-250 SD extra cab short box 4x4. 6.5" pro comp lift (all springs) 37" SSR's. I bought the truck this way and have no experiance with pro comp lifts. It looks like a 4wpw package jobbie.

Problem: Driving home I notice the steering wheel not so centered anymore going straight down the road. maybe 1/4 turn off of TDC to maintain a straight line. Get home get out of the truck and look at the rear tire. Its about 1/2 inch from eating the wheel well. The other tire is just fine. I look at the springs and the add-a-leaf is hanging by 4 or 5 inches and the small leaf from the pack is walking out too. Bump stop lift thingy and 2" lift block are still in original locations. There is a worn spot on the main leaf spring where the U-bolt plate was riding. The plate had moved 3 or 4 inches forward. It appears the centering pin in the spring pack had sheared. Sound right?

Can I use a grade 8 bolt to replace it? Will the head fit in the recess in the perch? Why did the leafs walk out but the small blocks stay put? U-bolts are still tight.

Also I heard that the track bar brackets were tearing themselves off of the axles on lifts this tall. True/false?

usually the hex head bolts are too big.. try a case hardened allen head bolt.. they are the black ones... with a nylon lock nut on it.. the blocks probably have a nipple on them that fits into a hole to keep them in place..

Thanks!

I went to my local Napa. Apperently this is a metric bolt. smaller than 7/16, larger than 3/8's. I bought the 3/8's one's just to get it back on the road. When I tore into it I noticed the U-bolts were barely tight. 2 turns of the wrench and I could remove them with my fingers. Now with the new center pin tight and the U-bolts tight I shouldnt have any trouble but I'll still keep my eye on it.

keep an eye on the ubolts be sure to check them every now and then just like any other lift

Hi there, i am also running the Pro Crap 6.5 " lift
i used all new leaf packs with a 2" block in the rear, i have had no troubles with anything so far, except the ride beats the living hell out of me when i drive across my pasture. the leafs packs are pretty damn stiff, i just towed a 25' goose neck with 100 bales of and i figured out weight was somewhere around 15000lbs including the trailer and it only saged my truck 4". for towing it is a good lift but going offroad will change your mind.

ut your right it sounds like your u bolts were too damn loose and just sheared the pin off.

Ben, I think my truck rides better than a stock SD but thats just me. Learn from my example and keep a really close eye on your U-bolts. I like towing with mine. THe 10" drop hitch looks pretty funny but it works great.
