Description

The USA Standard replacement Ring & Pinion gear set is engineered for Dana 80 differentials, offering a 4.56 ratio and a thick gear design compatible with 3.73-down cases. This set includes a 12-bolt ring gear and a 37-spline pinion, with a substantial 11.25-inch ring gear diameter. Constructed by USA Standard Gear, this component is built for durability and performance in demanding applications. Proper installation of ring and pinion gears is critical for optimal performance and longevity. It is recommended to consult with a professional or refer to specific service manuals for correct backlash, pattern, and bearing preloads. This gear set is intended for use with Dana 80 differentials, and while it is specified as a "thick" gear set for 3.73-down cases, users should verify compatibility with their specific differential housing and application.
