The GM 8.5/8.6 Ring & Pinion 3.08 Ratio by Motive Gear is an essential upgrade for truck and SUV owners aiming to enhance highway fuel economy while maintaining drivability. This ring and pinion gear set is designed to replace the factory gearset in GM 8.5-inch and 8.6-inch differentials, providing a numerically lower ratio that reduces engine RPM at cruising speeds.
The 3.08 ratio allows the driveshaft to turn 3.08 times for every full rotation of the wheel, which helps to address the common issue of over-revving when stock gears do not match your vehicle's tire size or performance goals. Manufactured to strict OEM tolerances, these gears feature precision-cut teeth for smooth, quiet operation and long service life, making them suitable for both street driving and light off-road use.
This ring and pinion set is particularly beneficial for owners of GM trucks and SUVs that have been lifted or fitted with larger tires, ensuring optimal performance and fuel efficiency on long highway drives. With robust construction and advanced CNC machining, these gears are built to withstand the demands of various driving conditions.
