Revolution Gear & Axle GM 10-Bolt 8.5in/8.6in 3.42 Ratio Face Hobbed Ring & Pinion Set

When you open this box, you'll find a complete ring and pinion gear set from Revolution Gear & Axle, ready to be installed in your GM 10-bolt 8.5 or 8.6-inch rear axle. This set features a 3.42 gear ratio, which is a popular choice for improving highway fuel economy by allowing your engine to run at lower RPMs on the interstate. It's a solid option if you're looking to change your current gearing for better cruising comfort or to better match larger tires.

These gears are manufactured using the face hobbing process, a well-built method that ensures precise tooth profiles for smooth operation and durability. This process helps to create a strong and reliable gear set that can handle daily driving and moderate towing. The 3.42 ratio offers a good balance between off-the-line acceleration and highway efficiency, making it a versatile upgrade for many GM trucks and SUVs.
