Revolution Gear & Axle 07-18 Jeep Wrangler JK w/35 Spline Chromoly Discovery Series Rear Axle Kit

Revolution Gear & Axle is known for making tough drivetrain components, and this Discovery Series rear axle kit for your 07-18 Jeep Wrangler JK is a prime example. If you're upgrading to larger tires or pushing your Jeep's drivetrain harder, a stronger rear axle is a smart move. This kit replaces your stock axle shafts with beefier chromoly units designed to handle more stress.

The core of this kit is the 35-spline chromoly axle shafts. Compared to the factory 32-spline shafts, these have more splines engaging with the differential, which spreads the load over a larger surface area. This significantly increases the axle's strength and reduces the risk of twisting or breaking, especially when you're off-road or under heavy acceleration. The chromoly steel material itself is well-known for its high strength-to-weight ratio, making these shafts both strong and relatively light.

This kit is designed as a direct replacement for the factory rear axle, meaning it fits right in without needing extensive modifications. You'll want to ensure you have the correct differential gears to match the 35-spline setup, as the factory differential may need to be replaced or modified to accept these shafts. This is a solid upgrade for any JK owner looking to improve the durability of their rear axle.
