Product Description

The Revolution Gear & Axle D44JK-513 5.13 Ratio Ring & Pinion set is engineered to significantly boost performance for the rear differential in the 2007-2018 Jeep Wrangler JK models utilizing the Dana 44 rear axle. Whether you've installed oversized tyres, increased your suspension height, or are towing heavy loads, this gear set delivers improved low-end throttle response and better vehicle control. The robust 8620 alloy steel construction and precision manufacturing ensure the longevity and reliability required for demanding off-road and towing applications.

Installation requires the removal of the rear carrier and proper setup of backlash, gear pattern and pre-load. This kit is a direct fit for the JK's factory Dana 44 rear axle and is optimized for lifted or upgraded setups - but you will need to reuse or acquire ring gear bolts separately. Fitment is confirmed for 2007-2018 Jeep Wrangler JK models with Dana 44 rear axle. Fitment for 2019-on (JL/JT) is **unconfirmed** at time of listing, so verify your axle, ratio and vehicle build before purchasing.
