Revolution Gear & Axle 84-96 Jeep YJ/Cherokee XJ Dana 35 Rear Koyo Bearing 4.56 Ratio Gear Package

This Revolution Gear & Axle package gives you everything you need to re-gear your Dana 35 rear axle to a 4.56 ratio, including a new ring and pinion gear set, and a complete set of Koyo bearings and installation hardware. Koyo bearings are well-known for their durability and smooth operation, making them a solid choice for this critical drivetrain upgrade. A 4.56 ratio is a popular choice for Jeep YJ and XJ models, especially those running larger tires, as it helps bring your engine's RPMs back into a more efficient range at highway speeds.

Inside this kit, you'll find a precision-cut 4.56 ratio ring and pinion gear set designed to work with the Dana 35 axle found in 1984-1996 Jeep YJ Wranglers and Cherokee XJs. The package also includes a full set of Koyo carrier bearings, pinion bearings, races, and seals, along with all the necessary installation hardware like the pinion nut, crush sleeve, and thread locker. Using quality bearings like Koyo helps ensure a quiet operation and long service life for your differential. This kit is designed to be a comprehensive solution for a complete differential rebuild.

When installing a new gear set, it's important to follow the manufacturer's break-in procedure carefully. This typically involves a period of moderate driving with no heavy loads or hard acceleration, followed by a few heat cycles. This process allows the new gear teeth to properly mate and wear in, ensuring optimal performance and longevity. This package is a great way to improve your Jeep's performance, especially if you've added larger tires.
