Product Description

Upgrade your Jeep Wrangler JK's rear differential with the Revolution Gear & Axle D44JK-456 4.56 Ratio Ring & Pinion set. Specifically tailored for the factory Dana 44 rear axle found in 2007-2018 JK models, this gear set is ideal if you've installed larger tires, added a suspension lift or demand stronger performance in off-road or towing applications. The 4.56 ratio provides a significant improvement in low-end acceleration and towing capability compared to stock gearing.

The kit features premium construction - 8620 alloy steel, precision gear-cutting and heat-treatment - to ensure long life under demanding use. Installation requires removing the rear differential, setting proper backlash and gear pattern, and re-using or sourcing ring gear bolts separately. Fitment is confirmed for 2007-2018 Jeep Wrangler JK models with the rear Dana 44 axle. Coverage for 2019 and newer models is unconfirmed at the time of listing, so verify your axle ratio and build before purchasing.
