Revolution Gear & Axle 2018+ Jeep Wrangler JL Non-Rubicon Chromoly Discovery Series Rear Axle Kit

If you're looking to beef up the rear axle on your 2018 and newer Jeep Wrangler JL that doesn't have the factory Rubicon package, this Discovery Series Chromoly Axle Kit from Revolution Gear & Axle is a solid choice. The factory Dana 44 axle in these non-Rubicon models can be a weak point when you start adding larger tires or pushing the vehicle harder off-road. This kit replaces the factory shafts with stronger chromoly units designed to handle more abuse.

This kit uses 4340 chromoly steel for the axle shafts, which is a well-known material for its strength and durability under stress. The shafts are a larger diameter than stock, measuring 1.35 inches with 35 splines, compared to the factory 1.125 inch, 30 spline shafts. This increased spline count and diameter significantly raises the torque capacity and overall strength of the axle assembly. The kit includes both the driver and passenger side axle shafts, along with the necessary seals and bearings to complete the installation. It's designed as a direct replacement for your stock axle shafts, meaning it fits right into your existing housing without major modifications.

When upgrading your rear axle, it's always a good idea to inspect your differential and gears for any signs of wear or damage. This kit is a critical component for any JL owner looking to improve their drivetrain's reliability for off-road adventures or towing. Make sure you have the proper tools and a service manual for your Jeep to ensure a smooth installation process.
