Revolution Gear & Axle GM 10-Bolt 8.5in/8.6in 3.73 Ratio Face Hobbed Ring & Pinion Set

This is a Revolution Gear & Axle 3.73 ratio ring and pinion gear set specifically for GM 10-bolt 8.5-inch and 8.6-inch rear differentials. If you're looking to change your vehicle's gearing, perhaps to better suit larger tires or to improve highway cruising RPMs, this set is a solid option. The 3.73 ratio is a popular choice for a good balance between off-the-line acceleration and fuel economy on the highway.

These gears are face hobbed, which is a manufacturing process that creates a strong, precise tooth profile for smooth operation and durability. This method helps ensure the gears mesh correctly, reducing noise and wear over time. Revolution Gear & Axle is known for producing well-built drivetrain components, and this ring and pinion set is no exception. Proper installation is key for any gear set, so make sure to follow the manufacturer's instructions carefully, including checking backlash and pattern.
