Core 44 Rear axle

G2 Axle & Gear

American-made CORE 44 housings accept the latest generation Dana 44 gear design, with a larger diameter ring gear and bigger pinion shaft to withstand hard off-road use. Our housings feature forged bearing caps and a unique G-lock adjuster nut system to set backlash and carrier bearing preload. CORE 44 axles use additional ribbing on the cast center section and 3-inch diameter, 5/16-wall DOM axle for use with tall, aggressive tires.

The CORE 44 is a direct replacement for the Dana 30 under the rear of your Jeep. All brackets are designed around stock mounting points, and are laser cut and CNC formed from 3/8-inch steel for added strength. We have also gusseted and reinforced any weak points to prevent damage to the brackets and finish the housing in a UV-stable black powdercoat.
