Product Description

The Revolution Gear & Axle DC-JK-NON Discovery Series Rear Axle Kit is engineered for **2007-2018 Jeep Wrangler JK** Non-Rubicon models equipped with a Dana 44 rear differential. These heavy-duty 30-spline 4340 chromoly rear axle shafts are built to upgrade the stock axles' strength and durability - ideal for off-road, larger tire applications, heavy payloads, or lifted builds. Bearings, seals, and retainers are pre-assembled for easier installation directly into the axle housing. 

The kit includes premium 4340 chromoly steel shafts with a direct bolt-on design requiring no modifications, plus ten wheel studs (not installed for safer transport) for complete reassembly with your existing hubs. Backed by a limited **10-year warranty** against manufacturing defects and axle breakage, this kit is a reliable replacement or upgrade for Jeep owners seeking stronger rear axle performance without the expense of a full rear axle housing swap.
