Product Description

The Revolution Gear & Axle D30JK-JL-456R ring and pinion set is engineered for the front Dana 30 axle of the Jeep Wrangler JK and early JL Non-Rubicon models. With a 4.56 ratio and reverse rotation, it offers a significant improvement in torque delivery, traction and responsiveness - whether you're navigating off-road terrain, towing or simply upgrading from stock.

Manufactured from high-grade 8620 alloy steel and precision heat-treated to OEM tolerances, this gear set is built to perform under demanding conditions. The reverse rotation design ensures proper compatibility with the front Dana 30 axle configuration present in these vehicles. For best results, proper installation including correct backlash, preload, and break-in must be followed.
