    Need some quick opinions, should I move my axel back an inch? I just finished putting in my shackle flip and new springs and it does look like it’s a little more forward then it was…I think:confused: Just want to get this right before I order my new driveshaft.

    If you're gonna do it, do it now...if your brake lines etc...are long enough, go for it!

    I would have to say yes on moving the axle back 1 inch. Are the springs going the correct way? alot of springs have a ft and a rear which will put the align pin in different position. Good to see another person from Colorado are you going to hit some trails this summer with the colo crew?

    Thanks guys I was thinking the same. The springs should be fine, I measured before I put them on they were the same distance form each end to the cernter pin. Probably just a side effect of the flip + 3' springs + SuperShackel's. So in with the zero rate and out w/ the overload spring!

    I'll be hitting the trails for sure, my web weeling days will soon be over!!!

    Leave the axle... hack the body. :D

    But yeah... that's the only real down side to a shackle flip.

    I would move it back. When you do a shackle flip it pushes the springs down which moves the axle forward slightly. to make it close to centered in the wheel well, move it back an inch.

    Please school me on moving the axle back. What's involved? I am ordering the DIY shackle flip next week.

    moving it back with a zero rate usually. OR, you can order the spring perches from DIY that have 3 holes in them so you can move the axle and not lift the truck anymore.

    www.offroaddesign.com www.jkwoffroad.com and some other sites carry zero rates.

    These are the DIY spring perches- [​IMG]
    These do involve removal of the old perches and welding these on.

    Yes, i would move the axle back at least 1.5".

    I am just finshing up some rear axle work. I installed a shackle flip several years ago though and ended up moving the axle back 1.5" to get the wheels much closer to center. What i am just finishing up is new superlift rear springs, new home made (maybe not so much home made but rather CNC made at my buddy's shop) spring perches with a 1" offset hole, and i flipped my springs around backwards since the center pins were 1" off from center. I will now have my rear axle 1" further back from stock. In my case the shackle flip moved the axle forward 1" of stock but the axle in stock form sat forward by about 1/2".

    Thanks Scott, I going to try moving it 1.5" back. Is there any side effects to the shocks after moving the axle back? I'm still using the stock mounting locations, so I would guess after moving the axel back one shock will be compresed more then the other, and they will also be working at different angle's, hopefully not enough to be an issue.

    I cut my fenders to make the axle be in the center of the wheel well but I will be flipping my 56s backwards to push my rear back as far as I can go and not get into my gas tank:D.

    That's my plan too, Ira. I should be getting to it the weekend after Thanksgiving. I'll post up how it goes.

    Taylor, I woud definitely move the axle back. You can redrill the perches and spring plates to do it. As far as shocks, if you have the equipment, I'd recommend making your own inboard shock kit with some angle and new perches. I'm going to mount my shock tabs right on top of the axle tubes.

    Hope to see you on some trails. I'll add you to my trail run notification list for next year. :deal:

    If you move your axle back 1.5" it will only be sitting 1/2" back from stock location and shocks won't be an issue.

    Thats the way to do it!

    And do away with the single shear setup the factory seemed to think was so good. Double shear always!

    another hijack, when you move the axle back, does it require a new driveshaft length or does it slip out of the trans?? i plan on this hopefully after the pick n pull half off sale! but probably much later.

    It would all depend on the lift and a few other factors.
