    I am rebuilding a 14bolt SF 9.5 8 lug rear axle, To go on a 1986 Jimmy.

    Does any know if 3/4 springs will bolt right in?
    And would they give me more lift?
    Where should I get bushings?

    Thanks for any input,
    Jeff

    3/4 ton springs? they won't give you any lift unless your stock 1/2s are worn out. They will not bolt right in. they are 56" long and the stock 1/2 tons are 52" long. Need to move the stock rear hanger back farther.

    Would u just use the 1/2 ton springs?
    B/c I will be towing a 3K pound stump grinder for the next year;after that I am going back to school, I then would use the truck as a daily driver, not as a work truck and, plan to buy lift springs and bigger tires.

    Thanks, Jeff
