GM + Chrysler AAM 11.5"/11.8" Nitro Ring & Pinion (4.30 Ratio)

AAM 11.5" / AAM11.8" 4.30 Nitro Ring & Pinion

Tech Notes: These are a premium aftermarket gear set that is far superior than your stock 11.5" gear set. These Nitro Gears are a true 11.8" diameter gear set and are a direct replacement for your 11.5" factory gear and also a direct replacement for 13-15 AAM 11.8" rear axle

Nitro gears are manufactured from 8620 steel gear forgings in the same manufacturing facilities as GM, Dodge, Ford & 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.
