Jeep Wrangler JK Gear Package Benefits:

Verified Fitment: With thousands sold, you can take the guesswork out of finding the correct gear set and mating bearing kit.

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.

Superior Strength and Durability: Revolution Gear and Axle is renowned for their commitment to quality. All ring and pinion gear sets are made from high grade steel using precision gear cutting and heat treatment processes that meet or exceed Original Equipment standards. This results in a product that not only performs exceptionally but also withstands the rigors of both daily driving and extreme off-road conditions.

Easy Installation and Quiet Operation: With over 40 years of manufacturing experience, Revolution Gear and Axle ring and pinions are preferred by installers for smooth and consistent setup. Our gear sets offer quiet operation, ensuring a comfortable ride without the annoying gear whine often associated with aftermarket gear sets.
