    hello all

    what are the differences between blocks and zero-rates?
    and why it is OK to use zeros in the front while blocks aren't suitable ?
    and can you please support your posts with pics


    thanks

    Ahmed

    Blocks get places between the axle and the spring, nothing other than the u bolts hold them in place. The u bolts can loosen and spit the block out. Not good. A zero gets bolted to the spring pack like it's a spring, but since it doesn't have the lenght to support any weight, can't call it an add-a-leaf. If the ubolts do loosen with zero rates, they won't spit out because they are bolted in.

    Not really sure, I was kinda wondering this myself. I personnally don't run them, don't need them just yet. But I want to do a SAS in my 97, I have the ORD shackle flip for the rear, and need more than the 4" it gives, so I thought about a 2" one with the offset to lift a little more, and relocate the axle. I would think that 2" would be the max, inless you run a traction bar or something similiar to keep axle wrap down.
