Review on ZG GM12P-373 - High Performance Ring & Pinion Gear Set for GM 12-Bolt Car Differential by USA Standard Gear by Bill Lacy

Revainrating 2 out of 5

Great replacement for 1990 Chrysler 9 1/4 Dodge RC

Perfect match for my 1990 Dodge Ramcharger with Chrysler 9 1/4. No positive difference in noise because my old one has been very worn since I've had it...the gear wasn't preloaded and the crush washer dug a hole in the gear. I have used this on an Eaton TruTrac LSD but it would fit on an OEM piece.

Pros
  • . Simply amazing!
Cons
  • Not bad, but...
