Revolution Gear & Axle 91-99 Jeep Cherokee XJ 8.25in Rear Timken Bearing 4.56 Ratio Gear Package

This Revolution Gear & Axle package gives you everything you need to re-gear the 8.25-inch rear differential on your 1991-1999 Jeep Cherokee XJ with a 4.56 gear ratio. Inside this kit, you'll find a complete set of high-quality Timken bearings, which are well-known for their durability and smooth operation. You also get the new ring and pinion gears, plus all the necessary installation hardware and small parts to get the job done right. This package is designed to provide a significant improvement in your Jeep's performance, especially if you've added larger tires or plan on off-roading.

Choosing a 4.56 gear ratio is a popular upgrade for XJ owners who have moved up to 33-inch or larger tires. This ratio helps bring your engine's RPMs back into a more efficient and responsive range at cruising speeds, making your Jeep feel more like it did with stock tires. The Timken bearings included in this kit are a standout feature, offering a solid foundation for the new gears and ensuring long-term reliability. Revolution Gear & Axle is a trusted name in drivetrain components, and this package reflects their commitment to providing well-built parts for serious Jeep enthusiasts.

When installing a new gear set, it's crucial to follow the manufacturer's break-in procedure carefully. This typically involves driving for a certain mileage without heavy acceleration or towing, and changing the differential fluid after the break-in period. This helps to properly seat the new gears and bearings, maximizing their lifespan and performance. This kit is a comprehensive solution for anyone looking to enhance their Jeep Cherokee's capability and drivability.
