Revolution Gear and Axle ring and pinion manufactured to be compatible with GM 8.5 Inch|GM 8.6 Inch differentials.

GM 10-Bolt ring and pinions are manufactured with the same gear cutting processes as the OE brands, utilizing a Face Hobbed or 2-Cut gear cutting style followed by lapping. Face hobbed gears can be easily distinguished by the equal gear height from heel to toe. Face hobbed gears produce lower noise and increase load carrying capacity compared to traditional face milled gears. Discover the unmatched benefits of upgrading your Ring and Pinion gear set and understand why it's an essential component in your vehicle.

Key Benefits:

Enhanced Capability and Performance: The optimized gear ratio improves torque delivery to the wheels, allowing for better traction and control. Towing performance is improved when you install the correct gear ratio for your vehicle setup by providing increased torque at lower speeds, making it easier to pull heavy loads without straining the engine. This means smoother, more efficient towing, whether you're hauling a trailer or carrying gear for your next adventure.

Increased Fuel Efficiency at Highway Speeds:Contrary to what one might expect, the right gear ratio can contribute to better fuel efficiency. By optimizing the engine's RPM at highway speeds, the ring and pinion gear set helps maintain a more efficient fuel consumption rate, saving you money and extending your journeys.
