    Default Leafspring install question

    I thought leaf's went on either side? My tub is real close to the correct position. axle looks way forward, (YJ 4" lift springs)

    Why does the axle look so far forward?

    Does it have adjustable centering holes? Some perches have three holes. also some springs are different in which way they orientate. I have a set of cj5 springs in my shed I will go measure them eye to eye tommorrow so you can compare.

    leason i learned the hard way, leaf springs are directional, both front and rear. sucks having to do thigs twice, but sometimes thats the best way to learn.

    they are directional. i mentioned about the pinion angle and shackle angle last time i was over. as you add weight like cage, seats, top, tire carrier it will drop the suspension and push the axle back. those springs are brand new as well and will take time to settle down to ride height. as they settle they will flatten out and push back abit.

    LOL, yea I guess it is; Well good rehearsal -now back to work after work tomorrow. Thats what I get for listening to someone that said either side didn't matter.

    They are YJ 4" springs but should be the same measurements other than lift. The perch does have 3 holes, but not enough to make up for this distance, my pinion angle will improve when installed the correct way lol.

    yes the perches allow you to stretch your rear usually 1.5 inches. And I have a feeling if you drop your springs and rotate them 180 you'll be good to go.

    that won't work cause all yj springs have a centered center pin and a 1.5" offset with perches is a bit much normally 1" is all you want

    add some weight and that will kick the shackle forward and move the axle forward

    I measured (just quickly) today from the axle tube to spring eye and it was 21" on both sides. Back of the tube to rear eye 21 and front of the tube to the front eye 21.

    I was comparing my pic with Hillbillies and his rear shackle is slanted outward to the rear, mine is is nearly vertical and maybe slightly forward, so the weight and settling would cause it to push back
