    I added a 6" lift on the back of my k5 and the wheel is too close to the front of the truck. It's about 2" off at ride height. I heard the zero rates can move the axle 1.5" but does anyone make one that moves it 2" or more? What other options are there?

    i'd use the 1.5's you want the axle forward kinda cause when it flexes it will hit the rear of the fender.

    Hmm, that's a good point. The zerorates are 1" high aren't they? I've already got 6" and going to seven doesn't really appeal to me. Does anyone make 1/2" spacers? Or I wonder if I can just drill a new hole in the spring perch and use that to move it? I guess I'd have to weld in some reinforcement since the the spring would be sitting off center of the axle centerline.

    if ur using stock length springs, the axle should be in the center of the wheelwell.

    Either move the spring mounts on the frame or change springs ... I'm presuming you used stock-replacement 52" springs? in which case the axle should be centered.

    or are they springs for some other application?

    Drill a new center hole (kinda hard to do but will work) in the spring pack.

    I got 2" tuff country springs and an ORD shakle flip. I may need to remeasure once I get the front tires back on so maybe 1.5" will be enough. I think they are still 52" springs, although the shakleflip supposedly moves the rear spring mount forward 1" to get a better shakle angle (or some other reason I don't know about)

    This is right from the Tuff Country installation manual:



    INSTALLATION MANUAL​


    2”, 3” OR 4” FRONT AND REAR
    SPRING SUSPENSION SYSTEM
    CHEVY PICKUP & BLAZER 1/2 TON
    1973 —– 1987
    PART # 14711

    Special Note: The new rear springs have an off set
    centering bolt, the longer end of the spring needs to
    be installed towards the rear of the vehicle.

    Yea, I saw that too. The longer end is toward the rear, I only found a 1/4" offset at most. Probably closer to 1/8".

    I remember when I did my lift, it was easier to eyeball the longer side then to measure it.

    Hey, if the trucks still in the air, switch them and see if it makes a difference.
    I had to go up and down 3 times to get the K5 saggy ass leveled out and its still off a inch. Sucks to have to do, but it had to be done.

    I wish I could tell you. it's only 2" off center at most. Do you have a chakle flip? The front is a little lower because it's on jack stands, so maybe that will change how much it looks off. Or maybe I just didn't measure very accurately. It's a good thing I asked. If no one else has this problem, maybe I need to remeasure or something.

    Actually, if i think about it, if you put the longer half of the spring towards the rear, the axle would be even more forward than if you flipped it around. i checked mine and they seems alomst the same size of each half of the center bolt. Mine are only 2" springs though, so maybe higher lift springs have more offset?
