Axle shift forward after new spring/shackle relocation

Wondering if anyone has run into this. I recently installed new OME CS033RA springs and ironman4x4fab adjustable shackle relocation kit. After install, the axle shifted forward.

I called ARB support, emailed photos, they believe the shackle relocation is the culprit. I'm going to remove the relocation tonight, see if it makes a difference.

Has anyone run into this? I'll try to post some pictures.

Only the center pins on the leaves determine axle location.

Err, the front mount and pin are what primarily locate the axle. Shackle can make a smaaaaaaaall difference in location, but on a 4' long leaf spring, that difference is tiny since it's the spring swings on such a long arc.

1) are your shackles backwards?
2) are the springs?

Shackles wouldn't make a difference....spring being backwards would move the axle back not forward.

Almost all springs have a shorter distance from the pin to the front than the rear....this lets the front have give the strength to handle power, and the rear have the flexibility (due to being longer and the shackle being at that end) for comfort and wheel travel.

can the o.p. have too large of a shackle added to a shorter leaf spring? would that push the axle forward as he has it?

im not sure if it looks funky from the wheel size or if hes really got something odd going on. it does look odd

Re: Axle shift forward after new spring/shackle relocation

The only thing that will change the distance from the front spring perch to the axle center pin is the payload. Add 500 lbs to the cargo area and take another picture. Drive around a few weeks with the same 500 lb payload and take a 3rd picture.
