Jeep Wrangler Differential Gear Package - Rear - Revolution Gear & Axle - Dana 44 Thick Koyo 4.88 Ratio - `96-`02. A direct-fit gear package for 1996–2002 Jeep Wrangler TJ rear Dana 44 Thick axles, providing a lower 4.88 final drive ratio for better performance with larger tires and heavier loads.

This Revolution Gear & Axle package pairs a 4.88 ring and pinion with high-quality Koyo components intended for the Dana 44 Thick rear axle found on TJ Wranglers. The 4.88 ratio reduces driveline RPMs under load and improves low-end torque delivery compared with stock gearing, which helps when running taller tires, trail rigs, or towing. The set is supplied for the rear axle configuration and is suitable for enthusiasts preparing axle upgrades or refreshes.
