Revolution Gear & Axle 2018+ Jeep JL Rubicon/JT Dana 44 220mm/210mm 5.13 Ratio 2-Cut Gear Package

The 5.13 ratio in this Revolution Gear & Axle gear package is a specific choice for Jeep JL Rubicon and JT owners looking to significantly alter their vehicle's gearing. This ratio is particularly well-suited for those who have upgraded to larger tires, often 37 inches or more, and want to restore or even improve their Jeep's on-road performance and off-road capability. By changing the gear ratio, you're essentially telling the wheels to turn more times for each rotation of the driveshaft, which helps the engine and transmission work more efficiently with the added rotational mass of larger tires.

This package is built around a 2-cut gear design, which is a common and reliable method for manufacturing differential gears. The 2-cut process ensures that the gear teeth are precisely shaped for smooth engagement and reduced noise. Revolution Gear & Axle has selected this specific ratio and design for the Dana 44 axles found in the Rubicon and JT models, which are known for their robust construction. The 220mm/210mm sizing indicates the specific Dana 44 axle variations this kit is designed for, ensuring a proper fit and function. This isn't just a simple gear swap; it's a comprehensive solution to re-optimize your Jeep's drivetrain for larger tires, impacting everything from acceleration to fuel economy.

When undertaking a gear ratio change like this, it's important to remember that both the front and rear differentials will need to be re-geared to the same ratio to maintain proper 4WD operation. This package is designed to be a complete solution for one differential, so you'll need to ensure you have the correct components for both axles. Proper installation, including setting backlash and pinion depth, is critical for the longevity and performance of these gears. Revolution Gear & Axle is known for providing well-built drivetrain components, and this gear package is no exception, offering a solid option for serious Jeep enthusiasts looking to maximize their vehicle's potential.
