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 4.10 gear ratio, including high-quality Koyo bearings. Re-gearing your differential is a common upgrade for Jeep owners, especially those running larger tires or looking to improve highway cruising comfort. A 4.10 ratio is a popular choice for Cherokees with 31-inch to 33-inch tires, helping to bring your engine RPMs back into a more efficient range at cruising speeds.

Inside this kit, you'll find a brand-new 4.10 ratio ring and pinion gear set, designed for durability and precise meshing. The inclusion of genuine Koyo bearings is a notable advantage. Koyo is a well-known manufacturer of bearings, respected for their strength and longevity, which are critical components in a high-stress environment like a differential. This package also includes all the necessary installation hardware and small parts, such as crush sleeves, pinion nuts, and sealants, to ensure a complete and proper installation. Revolution Gear & Axle is known for putting together comprehensive kits that simplify the re-gearing process for mechanics and DIYers alike.

When undertaking a differential re-gear, it's important to have the right tools and a clean workspace. Proper setup of the ring and pinion gears, including backlash and pattern checks, is crucial for the longevity of your new gears and bearings. If you're not familiar with this process, it's highly recommended to consult a professional mechanic or refer to a detailed service manual. This kit is designed to be a complete solution for upgrading your Jeep Cherokee's rear differential ratio.
