Revolution Gear & Axle GM 14-Bolt 10.5in Rear Axle 4.56 Ratio Thick Ring & Pinion Set

This Revolution Gear & Axle ring and pinion set features a 4.56 gear ratio, specifically designed for the GM 14-bolt 10.5-inch rear axle. The 'thick' designation means these gears are built to handle increased stress, making them a solid choice for heavier-duty applications where stock gears might not hold up. Choosing the right gear ratio is crucial for optimizing your vehicle's performance, especially after modifications like larger tires or engine swaps. A 4.56 ratio typically brings your engine's RPMs back into a more efficient range on the highway, improving acceleration and towing capability.

Crafted from well-built steel, this set is made to withstand the rigors of daily driving and more demanding use. The precision machining ensures proper meshing between the ring and pinion gears, which is essential for smooth operation and long-term durability. When installing a new ring and pinion, proper setup, including backlash and pattern checks, is critical for achieving the intended performance and lifespan. This set is a popular upgrade for those looking to re-gear their truck or SUV for better on-road manners or off-road performance.
