    Ok so back in 1997 a guy sold me 4x12" leafs and installed them...long story.. but anyway I got screwed on the deal... another long story...


    but all in all.. I am now realizing that I may not have 12" rear leafs.... so if you could....

    1. put a string from eye to eye....
    2. use a tape and measure down from string to bottom of leaf pack....


    what do you have?

    I have 12.5" with weight on the truck.... however.... I Know rear leafs already have a arch in them so im guessing I have 8" rears.....:doah:

    if you do have 8" rears, get a shackle flip, then you'll be riding even, and riding high :D

    all 12"and 10" lifts come with a 8" rear spring and the apprpriate block a 12" lift rear spring would be a custom deal

    No such thing as stock blocks on our trucks, GM used springs only so that block should be part of the lift kit. Also, I don't know of any manufacturer that makes an off the shelf rear spring larger than 8" so I would say you've got 8" rear springs with the accompanying block for a 10" kit. Custom springs are usually the exception plus I doubt anyone would have custom springs built and not eliminate the need for a block.

    i bought the truck back in 1990 and did a body swap to it... basically it was a 1979 chevy 3/4 ton camper special 8400gvrw... maybe that is why there was a block...

    the guy i bought the truck from barely did an oil change less add a block to a truck that was not lifted.....
