Flipping Spring Hangers to Lower the Ride Height? #104137 08/13/08 01:58 AM 08/13/08 01:58 AM

In looking at my factory stock hangers on the front of the rear springs, it looks like I can flip them (so the hanger hole is higher / closer to the undercarriage), which I believe will lower the car. Has anyone done this? How much does this lower the car? Anything to watch out for? '71 SSP - SOLD!

As you move the height, for every two-inches on one fixed-end (front or rear) you get 1-inch change in ride-height. If it's time for new springs (old ones worn out) you could order a new ride height set or have the old springs de-arched. Lowering-Blocks (mounted between the spring-pads and spring) are another option.

If a problem (angle) is detected, you can often fix/adjust with wedge-shims unless it is excessive, in which case you'd need to cut-off/weld-on new spring perch pads onto the rear-axle housing. Here is some info on checking D/S angles: http://www.streetrodderweb.com/tech/0203sr_drive_shaft_angles/index.html

I don't think I'd be lowering it enough to have to re-weld the perches though. Also, the springs are the XHD Mopar Performance springs. Does anyone know where to get good solid-steel lowering blocks with the correct U-bolts? I checked Summit, Jegs, Mancini Racing and haven't really found the right set for a '71 B. '71 SSP - SOLD!

I do remember using a set of Rancho (I think) aluminum blocks and with a little massaging and longer bolts they worked out great. I don't remember where I got them from though, it was a while back. good luck.

I did it on my Challenger, worked fine. Alternatively if you prefer to spend money or to not elongate the holes you can now buy bolt-in brackets that have several sets of holes...can't remember where to get them but no doubt someone else will.....

Or, if you really want to drop the car get the AR098 hangers. You might want to order the reinforcement plates at the same time.
