GM 8.5in Ring & Pinion 4.56 Ratio

The Motive Gear GM 8.5in Ring & Pinion 4.56 Ratio is a high-performance ring and pinion set designed specifically for General Motors 10-bolt rear axles. This gear set is engineered to enhance acceleration and improve low-end torque, making it an excellent choice for automotive enthusiasts and operators who require responsive gear ratios for off-road or towing applications.

With a 4.56 gear ratio, this ring and pinion set allows for approximately 4.56 wheel rotations per single driveshaft rotation, optimizing torque delivery during acceleration and low-speed scenarios. Proper installation with appropriate bearing preload and backlash adjustment is crucial for ensuring durability and minimizing noise or wear. This upgrade is particularly beneficial for vehicles operating in challenging terrains or requiring maximum pulling power.

Users who prioritize low-speed control and climbing capability will find the aggressive 4.56 ratio advantageous, although it may result in increased RPMs during highway cruising. This ring and pinion set is compatible with a variety of GM applications, making it a versatile choice for those looking to enhance their vehicle's performance.
