Revolution Gear & Axle 07-18 Jeep Wrangler JK Rubicon Koyo Bearing 4.10 Ratio Gear Package

This Revolution Gear & Axle package gives you everything you need to change the gear ratio in your 2007-2018 Jeep Wrangler JK Rubicon's differential to 4.10, using high-quality Koyo bearings. This specific ratio is a popular choice for Rubicon owners who have upgraded to larger tires, helping to bring your speedometer back to accurate readings and restore lost acceleration. The kit includes the ring and pinion gears, along with the complete set of Koyo bearings and installation hardware necessary for a proper differential rebuild.

When you're changing gear ratios, using bearings from a reputable manufacturer like Koyo is crucial for smooth operation and long-term durability. These bearings are known for their precision and ability to handle the stresses of off-road driving and daily use. The 4.10 ratio is a solid middle-ground for many JK Rubicon owners, offering a good balance between on-road drivability and off-road capability, especially when paired with tires in the 33-inch to 35-inch range. This package is designed to be a comprehensive solution, so you have the core components for the gear swap.

Changing your differential gears is a significant modification that requires specialized tools and knowledge. While this kit provides the essential gears and bearings, you'll also need to factor in additional supplies like gear marking compound, RTV sealant, and potentially a new pinion seal. It's always best to consult the manufacturer's installation instructions or a professional mechanic to ensure the job is done correctly, as proper setup is key to the longevity of your new gears.
