Leaf springs

Question for Cal-trac use. Can I use the offset hangers and shackles (perch moved in also) in a Cuda stocker?

Dwight Southerland · 05-22-2016, 08:47 AM

I believe that's a no. From the rulebook, Section 10A:3 "Shock absorbers,springs, or any other stock suspension component may not be moved or altered for any traction-bar installation except those traction bars that are equipped with a new spring perch."

Definition of perch, is that the part that attaches with u-bolts to rear? Just making sure we have the same terminology here. That part is furnished with the kit and the shock does attach to it like the original. Only part offset is the front hanger, using the same stock holes in frame. Probably won't need them anyway just using what I have.

The perch is the part welded to the bottom on the rear end housing that sits on top of the spring. This has to be in the stock location or width. The shock plate is what bolts under the spring. The cal trac bar and shock attach to this.

You can't use offset hangers. Plenty of room for the tires on an E body.

69-a-body, not e-body. But I can get them in there with a little " factory" tolerance and not use the offset hangers. Cal-Trac said they don't sell the hangers anymore, just bars and springs. From looking at the early Cameros and Mustangs they must have a lot of "massaging" to get those tires up under them.

If you have to weld on spring perches make sure to recheck housing for camber and toe change.

Yes, thanks, I'll weld them first before doing the ends since I made my own alignment jig. I'm going to buy the S60 center with just tubes instead of using the old one I have. I like having adjusters on the carrier bearings.

John makes a special narrow leaf spring
for exactly that application and that is what
most guys are using on 67 - 69 Darts out here.

John - do you know what the width of that leaf is?
