AAM 11.8 Inch 4.30 Ratio Dodge Chevy GMC Nitro Ring & Pinion

Nitro gears are manufactured from 8620 steel gear forgings in the same manufacturing facilities as GM, Dodge, Ford and Toyota. They are precision machined using computer controlled processes, heat treated, CNC triple-lapped and Rockwell tested for hardness. These extra steps ensure excellent fitment, ideal contact pattern and smooth, quiet operation.
Tech Notes: These are a premium aftermarket gear set that is far superior than your stock 11.5 inch gear set.

These Nitro Gears are a true 11.8 inch diameter gear set and are a direct replacement for your 11.5 inch factory gear and also a direct replacement for 13-15 AAM 11.8 inch rear axle
