Revolution Gear & Axle Jeep Wrangler JK/JL Dana 30 Reverse Front Axle 4.88 Ratio Ring & Pinion Set

Upgrade the front drivetrain of your Jeep Wrangler JK or JL with the Revolution Gear & Axle Dana 30 Reverse Front Axle 4.88 Ratio Ring and Pinion Set. Designed for reverse-rotation Dana 30 front axles, this gear set helps restore dependable power transfer and supports improved torque multiplication for applications using larger tires or modified gearing. The 4.88 ratio is well suited for off-road builds and vehicles that require stronger low-speed performance.
Manufactured for precise engagement, the Revolution Gear & Axle rgaD30JK-JL-488R set is intended to provide reliable operation when installed with the proper setup components and professional gear-mesh adjustment. Correct installation is essential for achieving appropriate backlash, contact pattern, preload, lubrication, and long-term durability. Always verify axle configuration, carrier compatibility, and vehicle application before ordering, as reverse front axle gearing differs from standard front axle designs.
This ring and pinion set is a practical choice for Jeep owners, builders, and technicians completing a drivetrain regear on compatible Wrangler JK and JL models. It is supplied as a matched gear set for the Dana 30 reverse front axle and is intended for automotive use. Installation should be performed by a qualified technician familiar with differential service. Confirm the required installation kit, carrier break, spline configuration, and ratio compatibility before beginning the project.
