Revolution Gear & Axle GM 10-Bolt 8.5in/8.6in 4.56 Ratio Face Hobbed Ring & Pinion Set

If you're looking to change your vehicle's gear ratio for better performance, a ring and pinion set is what you need. This set from Revolution Gear & Axle is designed for GM 10-bolt 8.5-inch and 8.6-inch rear axles, featuring a 4.56 ratio. This ratio is a popular choice for those who have increased tire size or want improved acceleration over top-end speed.

What sets this set apart is the face hobbing process used for the gears. This advanced manufacturing technique creates a stronger, more durable gear tooth profile compared to traditional methods. This means the gears can handle more stress and last longer, especially in applications where the vehicle sees heavier use or is modified. The set includes both the ring gear and the pinion gear, ensuring you have the matched components for a proper installation.

When installing a new ring and pinion, it's crucial to follow the manufacturer's break-in procedure. This typically involves a period of gentle driving with no hard acceleration or heavy loads to allow the gear teeth to properly seat. Proper installation and break-in are key to getting the most out of this well-built gear set.
