Revolution Gear and Axle Ring and Pinion Sets with Koyo Bearings
Re-gear your Jeep the right way with Revolution gear and axle ring and pinion sets paired with Koyo bearing master install kits. These popular packages take the guesswork out of matching gears to the correct overhaul components--delivering improved torque to the tires, better control off-road, and restored drivability after adding larger tires. Built from high-grade steel with precision gear cutting and OE-level heat treating, Revolution ring and pinions are installer-preferred for consistent setup and quiet operation. Drive it on the street and punish it on the trail with confidence when you order the Revolution gear and axle ring and pinion sets with Koyo Bearings best suited for your application.
More product features, items, specifications, and notes include:
* Variety of available gear ratios, from 4.10 to 5.38 (application dependent; availability varies)
* Helps optimize gearing for improved torque delivery, traction, and control (especially with tire size/weight changes)
* Can improve towing performance by bringing usable torque in sooner at lower speeds
* Proper ratio selection can help maintain efficient highway rpm for better overall drivability
* Installer-friendly setup for smooth pattern dialing and quiet operation versus whine-prone gear sets
* Master kit typically includes the core overhaul components (bearings/races, shims, seals, and necessary hardware); exact contents vary by application
