Jeep Wrangler Differential Install Kit - Rear - Revolution Gear & Axle - 4.88 Ratio - 1996-2004 is a direct-fit gear package and installation kit engineered for Jeep Wrangler TJ rear Dana 35 applications. This kit supplies the gears and components needed to achieve a 4.88 final drive while retaining factory mounting points.

Designed for enthusiasts who want predictable gearing for larger tires or off-road use, this Revolution Gear & Axle package focuses on correct tooth geometry and matched components to maintain smooth engagement and reliable operation. The kit includes precision-cut ring and pinion gears with compatible bearings and seals, reducing the need for sourcing separate parts. Properly installed, the 4.88 ratio improves torque multiplication without changing transfer case or transmission components, giving better hill-climb and low-speed control.
