  1. Would I be able to run 33s on a 20×12 rim ??

  2. Will this fit a 2018 Sierra 1500 on 33s with 22x12s -44 offset?

    • Niguel, very sorry for the delay. There would be major trimming necessary to fit that set up on only a 4″ lift kit. I would recommend going up to a full 6″ lift for that set up.

  3. With this lift kit, what restricts my ability to have stock 18” rims for a 2015 silverado Z71? I am already set up with 275/70s on a level kit…

    • The inside of the wheel will interfere with the new control arm. If you run spacers you can use factory wheels at your own risk.

  4. Does this give you a true 4”lift on the truck? It seems like the strut spacer and rear block is small when comparing to other 4” kits

  5. How are the CV angles with this one? I’ve seen that the basic lift buts them back damn near straight. Is this one do about the same

    • Yes, very nice CV angles on these lifts as they use a full diff drop that requires you to cut the crossmember and diff.

  6. Does it fit a 2015 Chevy Silverado 1500 Double cab

  7. I’m a bit confused with the vehicle factory equipped w/ options. First one is just that, then there is cast steel, and third is cast aluminum. But the part number for this kit says it’s cast steel? If the part number for kit says it’s cast steel why are there other options? Please forgive me. I’m a noob when it comes to this stuff

  8. How much is this kit with the front drop cross member. Like the one in video with the black 2015 Silverado?
