    I've been reading about the Ford spring conversion and it says the spring bolt is something like 25 inches from the front of the spring eye. Stock, it's something like 26. They say to redrill the spring pack to fix. Could you just flip the spring around backwards? I would like to relocate the axle rearward a few inches to get a better departure angle and to get a better driveshaft angle anyway{gonna sawzall the rear of the fenderwells}. Anyone know the distance from the rear spring eye to the spring pack bolt? Any ideas on this, especially as far as spring wrap goes?

    So the spring bolt is in the middle? Wait, if were in the middle and the the distance to front spring eye is 25 inches then the spring would be 50 inches over-all-25 inches to the front and 25 inches to the rear.
    Am I missing something? Were did the other 7 inches of spring go? /forums/images/graemlins/confused.gif

    yup that 7" is on the back side
    so running the backward without drilling would move the axle 6"
    could be off but that makes sense to me

    I have a set in my garage, so I went out and checked them out and sure enough, mj is right on the money. 32" from the center pin to the spring eye on the back.

    I'm running my 57s backwards for exactly that reason. However, you have to watch things like geometry changes as the spring flexes when you do that. Specifically pinion angle can be a problem due to the axle being mounted on the back of that arch.

    Oh yeah, I got plenty of axle wrap, working on getting a anti-wrap bar in there now. Those springs don't control the wrap at all turned backwards. The band is on the wrong side and the leafs are too staggered on the back (now the front) to provide the resistance to wrap...

    Nope, those are too heavy, they would only be good (potentially) as donors to play with swapping leafs in and out. You definitely want the 4 leaf (plus overload is 5) F150 springs.

    I get mine at a local yard for $60 a pair. Some people claim to get them cheaper but that seems to be as cheap as it gets around here. Most are quoted at $100 a pair. I would be a bit suspect of the quality of J.C. springs, I would much rather get a set of Ford's. Just make sure they come from a truck that does not look totally beaten on...

    You're doing good at that price Russ /forums/images/graemlins/deal.gif.... My best has been about $90 a pair, 'cept for 1 "u-pull-it" lot that I visited once.

    The junk (and I do mean JUNK) yard where I got mine sells em for $60 a pair, they pull em, and they have 20+ pairs there. The spring swap is still a secret in Nebraska! /forums/images/graemlins/thumb.gif Wait...maybe it's because we don't have any rocks! /forums/images/graemlins/eek.gif

    New ? same topic:

    Aren't the ford springs wider than the Chevy? Were you able to use unmodified Chev springhangers? /forums/images/graemlins/ears.gif
