Product Description

The Revolution Gear & Axle DC-D30-TJ 4340 Chromoly Front Axle Kit offers a serious strength upgrade for the front Dana 30 axle in Jeep Wrangler TJ/YJ and Jeep Cherokee XJ platforms. Built with premium 4340 Chromoly shafts and oversized U-joints, this kit was developed to handle high-stress conditions including rock-crawling, lifted suspensions and heavy off-road loads, while maintaining potential for street use.

Installation involves removing your factory front shafts, installing the new Chromoly inner and outer shafts, fitting the large U-joints and securing with the included full-circle snap rings. Because this is an upgrade kit, you must verify your axle is a Dana 30 front and confirm spline count, U-joint compatibility and stub shaft configuration before ordering. The kit is ideal for serious Jeep builds where axle strength is critical.
