    Default Block Question

    Hey guys i have a question about the stock blocks on a truck. when i put my lift on i took the stock
    1 1/2 blocks out and installed the new 6" blocks. my question is i just seen a new 2500hd with a 6" lift with the new blocks installed on top of the factory blocks. is that right? i mean i 'm sure he had someone do it for him (works at my wifes bank) but i was just wondering if anyone has done this or is it totally wrong. i wouldn't think it would be safe to put the blocks ontop of each other but just wasn't sure.......

    I would not risk it. It's too easy to be flexing your axle and have the blocks spit out. If anything, get longer shackles or higher-arched springs. It's very dangerous to be stacking them that high.

    I do not think that is safe at all. The blocks with my lift replaced the OE blocks.

    Some states its even illegal to stack blocks. Very unsafe!
