    Title says it all... The truck I took the lift off of had 4" blocks with the shorter end of the block toward the front of the truck. Dad says they're backwards and he'd bet me $100 bucks. I've not tightened anything down so it wont be hard to jack it up and try the other way to answer the bet, but thought y'all might save me some extra work since I'm against the clock to get this thing going by this weekend. I hope he's right cause it looks as if the rear driveshaft is in a serious bind. I swear this lift has gotta be 6" because 36" TSL's fit easy, but we trimmed the fenders just to get rid of some rust, lol.

    you basically need to try to point the pinion up more towards the t/c, so yeah, if you have the small end forward, they are backwards

    Actually, if you're trying to point the pinion up some then the short side needs to go forward since the springs are on top of the axle and the thicker part of the block being in the rear would help to point the pinion up farther.

    DAMN YOU !!! you made me go actually look at mine,,:p:

    you are correct, i for some reason had it all backwards in my mind, which isn't real hard to do lately:crazy:

    The thinner side DOES point to the front.

    I'm a winner!!! OK maybe not, I think dad's adding up what it cost to raise me now, so I'm way in the hole.

    Thanks for your help.
