Revolution Gear & Axle 07-18 Jeep Wrangler JK Non-Rubicon Timken Bearing 5.38 Ratio Gear Package

If you're looking to significantly change your Jeep Wrangler JK's gearing, perhaps to accommodate larger tires or improve highway performance with a different axle ratio, this Revolution Gear & Axle package is a solid choice. This specific kit offers a 5.38 ratio, which is a popular upgrade for JK owners running 37-inch or larger tires, bringing your engine's RPMs back into a more manageable range at cruising speeds. It's designed for the Non-Rubicon models, meaning it's intended for the Dana 30 front and Dana 44 rear axles found on those Jeeps.

What sets this package apart is the inclusion of Timken bearings. Timken is a well-known name in drivetrain components, and their bearings are respected for their durability and smooth operation. This means you're not just getting new gears; you're getting a complete installation kit with high-quality bearings that are crucial for the longevity and proper function of your differential. The 5.38 ratio is a substantial change from stock, so expect a noticeable difference in how your Jeep accelerates and cruises. This kind of re-gearing is often done when a vehicle's overall weight or tire size increases significantly, as it helps the drivetrain work more efficiently.

When undertaking a gear change like this, it's important to have all the necessary installation components. This kit is designed to provide the essential parts for a proper re-gear, but always consult the manufacturer's installation instructions to ensure you have everything needed for your specific project. Proper setup and break-in procedures are critical for the performance and lifespan of new gears, so be sure to follow those guidelines closely.
