Revolution Gear & Axle 07-18 Jeep Wrangler JK Rubicon Koyo Bearing 4.56 Ratio Gear Package

Built with Koyo bearings, this Revolution Gear & Axle package is designed to give your 2007-2018 Jeep Wrangler JK Rubicon a 4.56 gear ratio. Changing your differential gears is a significant upgrade, especially if you've modified your Jeep with larger tires or plan to. A lower ratio like 4.56 helps bring your engine's RPMs back into an optimal range at cruising speeds, improving drivability and restoring lost acceleration. This is crucial for maintaining proper transmission function and fuel efficiency after tire upgrades.

This kit includes everything you need for a complete differential rebuild, featuring high-strength ring and pinion gears manufactured by Revolution Gear & Axle. The inclusion of genuine Koyo bearings means you're getting top-tier components known for their durability and smooth operation, essential for handling the increased stress on your drivetrain. The 4.56 ratio is a popular choice for JK Rubicons running 35-inch to 37-inch tires, offering a good balance between on-road manners and off-road capability. Proper installation is key to unlocking the full potential of these gears, so be sure to follow the manufacturer's instructions carefully.

When undertaking a gear change, it's important to have all the necessary installation components. This package is designed to be comprehensive, but always double-check the manufacturer's recommendations for any additional fluids or sealants you might need. A professional installation is recommended for this type of drivetrain work to ensure proper setup and longevity of your new gears.
