4.56 Ratio Ring and Pinion Gear Set

The USA Standard Ring & Pinion gear set is designed for GM 7.5" and 7.6" differentials, offering a 4.56 gear ratio. This set includes a 7.50" ring gear diameter, a 27-spline pinion, and 10 ring gear bolts, ensuring precise fitment and performance for your rear-end components. The 4.56 ratio is a popular choice for applications seeking improved acceleration and towing capability, especially when paired with larger tires. Installation of a ring and pinion set requires specialized knowledge and tools. It is recommended that installation be performed by a qualified mechanic or differential specialist to ensure proper backlash, gear pattern, and setup. Failure to install correctly can lead to premature wear or catastrophic failure. This gear set is compatible with specific GM 7.5" and 7.6" axle applications. Customers should verify their axle model and specifications before purchasing to ensure correct fitment.
