What do you consider cheap ? And where is this place you get them from "cheap" ?





$ 19.99 a pair..


you didnt read my post did you...

John, The SS springs came on the car.

I wish I could find it, but there is an article on the web with a dodge wagon where the guy used SS springs and put a leaf spring wedges in it that were WAY over 4 degrees. thick ones, probably 2" at the thickest point. The owner of the car said he got them from a 4x4 truck parts store.

regardless, what degree should I be trying to achieve? and is there a drawback using the wedges to achieve the angle? the thicker blocks would actually lower ride a bit.


I’m listening.

I would cut the perches off & reweld them at the correct angle.... If you use more than 4 degrees of shims you'll find the center bolt no longer has good penetration into the axle... Really ever 4 degrees is more than I like...

Understood. But what should the final pinion angle be?

find the straight line from the tailshaft and the pinion shaft. drop the nose of the diff 2 to 4 degrees down from there.

Nose down should refer to relationship between driveshaft and pinion angle, not pinion to horizontal. I have seen a few that "appeared" nose up, but when measured were actually spot on. I think the mopar chassis book does a good job of covering this in detail (with pictures). My street/strip car has been running SS springs and 5 - 7 deg. nose down for over 12 years with no issues.

I read your post. Considering Mancini has them for $27 a pair or 3 for $100 for a solid shim I guess the 19.99 hollowed out ones are cheap. My concern would be that the cheap hollowed out ones would be more likely to crack and fall out.

You definitely need to adjust the rear so the pinion is nose down. If you want it to sit lower then put them back in the upper holes and get angle shims for under the perches, but to they make shims big enough to go negative ? you may have to cut the perches off and have them rewelded on ???

What is making you go with SS springs ?




He ever answered your question,I would also like to know !!

The trans output shaft and rear yoke should be on the same plane and both should be about about 2 degree angle in relation to the driveshaft for a street driven car. In most cars, the engine/trans will be installed in the car at about a 3 degree angle trans down relative to the chassis (this is why intake manifolds are taller in the back than front; to level the carb). This means that the rear needs to be at about a 3 degree angle nose up (relative to the chassis) to be on the same plane. With the driveshaft installed, the angle between each and the driveshaft should be 2 degrees, no more than 3, because u-joints are designed to safely work between 1-3 degrees.

Yes he did , they were on the car when he bought them.

I'm not sure what the spec is supposed to be , I haven't had to deal with this issue ... yet.

Way to many people on here complicate teh pinon angle issue, it is between the drivesahft and pinon gear, not the dang trans angles

Lightbulb just came on. I'm a very visual person and pictures help. I'll get the chassis manual and give it the once over.

The main reason I would be keeping these springs on the car is Rick Ehrenberg's "Green Brick". He runs two right side springs on that car and I like his theory behind it and the way it performs.

Thanks all for the encouragement and help!

I had a similar problem with my shackles pointing towards the front of the car when I installed the S/S springs on my 68 roadrunner. When I first installed them and lowered the car back on the ground, my shackles looked just like yours do in the photo. My car sat really high as well. My dad looked at it, grabbed a long pry bar, and just levred both shackles backward. The car lurched a bit and then sat very nicely with the shackles pointind down and slighltly to the rear. If I remember right I just added a 2 degree down shim to get the rearend to 5 degrees down. It's been like that for the last 10 years. Every time it gets jacked up without weight on the wheels, the shackle moves forward and has to be levered back to the correct postion once it is back on the ground again.

Aha! Mine needed no pry bar, but I see what you are saying for sure. My engine and trans aren't in the car yet. When we get there, I'll install the driveshaft and degree everything. This has been WAY helpful.
