Quick Ship SKU #: NG-AAM118-430-main Nitro Ring and Pinion Gear Kit 11.5" AAM Solid Axle 03-12 Ram 2500 / 3500 / 01-13 GM 2500HD / 3500

Nitro Gears are made from 8620 steel gear forgings and manufactured in the same facilities as major brands like GM, Dodge, Ford, and Toyota. They undergo a precision machining process using computer-controlled techniques, followed by heat treatment, CNC triple-lapping, and Rockwell testing for hardness. These additional steps guarantee an excellent fit, ideal contact pattern, and a smooth, quiet operation. Tech Notes: These premium aftermarket gear sets are far better than the stock 11.5-inch gear sets. Nitro Gears are true 11.8-inch diameter gear sets, and they are a direct replacement for your 11.5-inch factory gear and also for the 13-15 AAM 11.8-inch rear axle.
