Nitro Gear and Axle strives to provide the highest quality differential components available. We take the steps necessary to ensure our parts are dependable. Our product range is continually growing to meet the needs of consumers for new ratios and applications. At Nitro we know differentials, and know what it takes to provide you with high quality components. 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.
