SpringsPosted by: Dan Robinson on 02/22/04
Mopar Performance sells new leaf springs. The ones I bought were around $150 for the set. Can't much beat that. The shops around here wanted almost that to re-arch a set of old ones.

Once again Ken Garrett came to my rescue with an idea to get the springs re-arched at a local shop here in Charlotte. This turned out to be just what I needed. Priced under $200.00 was a lot better for the results I needed.
I installed the "new" springs with new bushings and hanger bolts etc. The work was dirty but I had it done in an afternoon.
Raising or Lowering the Rear EndPosted by: Robert Spelic on 12/08/05
I have raised and lowered mine for racing purposes. In fact way too many times. After trying the easy way (Air shocks), I ended up with new springs. I tried about 3 different sets of springs until I got the right "attitude". I think the air shock route is still the cheapest route if cost is the limiting biggest factor in raising the car.
It took about a year of farting around before I finally added a set of front eye spring brackets (John P. sells a good bracket), that has multiple holes drilled in it that enables you to move the leaf spring front bolt hole up and down and also forward and back. With all that adjustment it is possible to raise and lower the rear about 2". If the car is not low enough, a lowering block (2" block of aluminum) can be installed between the leafs and the axle tube.
There are many other things to be wary of when changing the rake of the car and those include making sure the pinion angle stays in the 3 to 5 degree nose down range, that the driveshaft length is still OK if you move the rear-end back some, and that the spring perch location pin (and "anti-rotation" pin) stay engaged if a lowering block is used.
Be sure to post what your going to try here first and see if anyone has done that and what challenges that ran into. Air shocks are certainly the easiest.
