Is this a rear only shackle? Front and rear? If you use it/them wouldn't you also have to move the spring perch the same distance? I've also heard about the 3" (inboard) spring relocation which, I believe, requires new perches on the axle. This 3" re-location basically puts the springs directly below the rear frame rails. This process allows wider wheels/tires and possibly mini-tubs. Please enlighten me about the offset shackles!!

I installed a B-body Dana in my F-body. The spring locating pin is about 3/8" different between the two. Using the offset spring hangers in the rear made the pins line up in the Dana nicely.

In a demon/duster a 275/60/15 on 8" wheel will just about kiss the springs with the tire. Getting this setup is sorta like a mini mini tub- lets you use more of the wheelhouse that's already there.

The narrower b-body rear allowed the use of bigger rims/tires. Problem is they also require the use of SS springs, which make the car sit too high IMO. You could redrill the front hanger I suppose.

That's incorrect, the spring centering pins on a stock E-Body are 46 inches apart. The sprig centering pins are 44 inches apart. The offset shackles/hangers only move the springs in 3/4 of an inch on each side. that's 1/2 inch shy of what's needed. You can force the springs in to make them reach but that puts them in a bind. Bad idea. Kayse can't keep up at all now. lol

I also thought that there was enough slop in the system without being to worried about leaf binding. It was a quick low buck improvement, with little downside. Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

Doesn't that bind the spring as stated earlier? As far as tire clearance goes, if the axle tube perches don't move then there is not much to be gained. Why not just do the 3" relocation front, rear, and axle tube perches?

Can be used to bolt B-body rearend into E-body with no modifications $175 DoctorDiff E-body 1″ offset spring hanger/shackle kit for Superstock springs. Can be used to bolt B-body rearend into E-body with no modifications $185 DoctorDiff �71-�74 B-body 1 1/4″ offset spring hanger/shackle kit for standard springs $185 The way I understand it, the 1" offset kits allow you to use your stock rear leaf spring perches and offset designed front spring hangers. The 3" kits require you to cut a notch in the frame and weld the new front spring hangers in there, as well as relocating the rear shackles into the frame rail, eliminating the rear leaf spring perches. I think both kits require you to move the axle tube perches, unless he sells a spacer plate for the 1" kit...? I the 3" kit I know requires moving the axle tube perches.

The perch on axle HAS to be re-located the same amount inboard on axle tube. You can get the perches many places, including dr. diff.
