I ran one on my car. I had it touching the floor pan at rest. caused nothing but problems and eventually broke the tail housing. I diched it, copied 572 spring set up and the car launched much better. My advice is to pitch it. Clamping the springs had much more of effect than the snubber ever did.



I actually had the exact opposite problem. The pinion snubber broke and I didn't know it. The car kept breaking tailshaft housings/loosing bushings/etc...

I found the broken snubber, put it back in, and never had another trans problem again.

I will admit that the car had a slightly short drive shaft, but basically the snubber prevented the axle from winding up, and pulling the driveshaft out. This was on an 11.80's 340 duster...
