    Are the lengths different from the 1/2 and 3/4 ton rear springs and the 1 ton rear springs? More to the point, will the skyjacker 88-98 style 5" rear springs fit the back of a 1 ton?

    I'm pretty sure they are all 63" long on all the IFS trucks, the one-tons just have more leafs added to increase the spring rate (stock).

    If Skyjackers 5" kit is anything like thier 3" kit, it seems like it's allmost stock spring arch except they added one more short leaf to the pack and increased the thickness of the over-load spring to nearly an inch. (thats on the 3" kit, I don't know about the 5" inch pack)

    I would think the 1/2 spring pack would fit a 1-ton, but it might loose some height.
    I bet Sky-jacker would have the correct spring for one-tons in stock.

    Thanks for the info. The 52 and 56" springs are on the older, non IFS trucks. I just wasn't sure how it was on the IFS rigs. I'll shoot skyjacker an email and ask about it. I would rather have a higher load rated spring for the back, I'm going to run air bags to raise the load carying capacity back up anyway. Anyway, thanks for the info.
