JK Non-Rubicon 4.11 Ratio Gear Package (D44-D30) with Timken Bearings (Front Carrier Required When Upgrading From Factory 3.21 Ratio Only) Revolution Gear and Axle

This complete regear kit for front and rear axles is designed to restore lost power and performance in Jeep Wrangler JKs (non-Rubicon models from 2007-2018) after installing larger tires, a taller lift, heavy-duty armor, and overland gear. It includes high-quality heat-treated ring and pinion gears built to OEM specifications, ensuring smooth, quiet operation on and off-road. The package also contains master install kits with Koyo bearings for both front and rear axles (D30 Front / D44 Rear). By switching to a numerically higher gear ratio, this package aims to improve throttle response, drivability, torque delivery, and potentially fuel efficiency by maintaining optimal engine RPMs.
