I'm working through all the plans to throw D60's under my bronco2. I'm going to use leafs front and rear, will be using a stock or possibly 4" lift leaf for the front and keep my 6" leafs in the back. I'll be putting the leafs under the frame so I'll get a little more lift there but my question lies in shackles. I was thinking revolvers but have heard they are junk and unload un-expectedly anyone have experience with these? How about a buggy leaf with a normal shackle? I don't plan on running this thing on the road but I want it safe enough to do so if I choose.

Also, why do jeep and ford put the shackle in the front of the front spring if so many people are changing it back for better ride and handling? What is the benefit of having the shackle in front of the spring, I can think of a dozen cons, any pros?

I know with the shackle forward it will keep your pinion angle mostly inline with your driveshaft. With a shackle in the back, it will unload going up hills and push your pinion down.

Well if the shackel is in the front the axel will moov to the front when u compress the springs and when u hit a hill or bump the axel will move toward the bump and it will hit allott harder .On the plus side u can run ladder bars for stability.With the shackel in the back (like my SAS ) when u hit a bump the axel moves with the shackel toward the back and the ride is softer ,On the doun side u cant run ladder bars cuz the axels natural movement is back

Mainly the ride is the most affected area when placing shackel front or back.Most think back is better

A shorter shackel will not unload as much as a longer one

Also a factory leifspring truck like a older half ton ford have negitive arch springs with a front shackel then the spring pulls the shackel back and the axel goes back anaways
