Toyota 8.2", 4.88, Nitro Ring & Pinion

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.
