    a good auto parts store will have a longer center bolt and my local auto store even makes u-bolts to order, cheap.

    In a pinch a grade 8 bolt will work. Get the right length and size and round off the head of the bolt to the size of the pin that fits your axle. Thats a last ditch effort though. Like Blizzard said, the pins arent as hard to find as one might think. Go with new u bolts too. Small investment and alot safer!

    I replaced the springs on Chevy a few years ago... What I did was keep the main stack of springs the same but added a couple extra to the overloads.... my thought is that when empty the ride would bee the same but the extras would help when loaded...

    I had a shop add 2 springs to my 96 k1500 a couple of months ago. Total cost was around $500 for parts, labour and everything. No headaches trying to figure out centre pins either. :dizzy:

    if its going to cost me 500 i wouldnt even consider it, i would just do airbags and be done. im just going to throw 2 extra springs in there and arc them and be done. good days project!

    How many leaf pack on your truck now? 4 then I recommendation go with 6 packs with 1 thick leaf pack.

    My F250 have 6 packs but that wasn't enough for me so I went bought F350 dually with 7 leaf packs plus 2 overload leaf spring.

    A socket head bolt will work nicely for the center pin. If I remember right, I didn't have to grind them down at all for them to fit into the hole in the spring perch. They are often available in grade 8 (required).

    I used large c-clamps to hold the spring pack together and reassemble. It's real easy to do and only takes an hour or so tops as long as everything is ready to go.

    johnny u, did you happen to use different clamps like the ones in the stock postion twards the end of the leafs? closer to the shackles.

    just go to NAPA and get new center bolts, they have threads all the way down so get a longer than you need and run the nut down and cut off the rest after you tighten it

    I didnt reuse any clamps since I was rebuilding those packs for flex (in my chevy crawler).
