4.56 RING & PINION D35 YJ TJ

Bigger wheels and tires need bigger gears! The Crown Automotive Dana 35 Ring and Pinion Kit 4.56 Ratio is made for the Jeep rear axle and designed to supply you with everything you will need to upgrade your rear differential. With taller gears you can relieve some of the extra stress that has been put on the engine, restore smooth shifting and maybe even help your fuel economy. This gear ratio requires an existing carrier with 3.73 or higher gear ratio. Don't forget the speedometer gear to calibrate ground speed to the new ratio.
