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

This is the Revolution Gear & Axle 5.38 ratio ring and pinion gear package, specifically designed for the 07-18 Jeep Wrangler JK Rubicon models. If you've upgraded to larger tires or are looking to improve your Jeep's performance on the trail or highway, changing your differential gear ratio is a key step. A 5.38 ratio is a popular choice for JK Rubicons running 37-inch or larger tires, helping to bring your engine's RPMs back into an optimal range for better acceleration and fuel efficiency.

What sets this package apart is the inclusion of high-quality Timken bearings. Timken is well-known for producing durable drivetrain components, and their bearings are built to handle the stress and heat generated by heavy-duty use. This kit includes everything you need for a proper installation: the ring and pinion gears themselves, all the necessary Timken bearings, and installation hardware. Revolution Gear & Axle focuses on providing well-built components that offer a significant improvement over stock, ensuring your Jeep's drivetrain can handle the demands of off-roading and daily driving.

When installing a new gear set, it's crucial to follow the manufacturer's break-in procedure carefully. This typically involves a period of moderate driving without hard acceleration or heavy loads, followed by an oil change. This process allows the new gear teeth to properly mesh and wear in, ensuring long-term durability and quiet operation. This package is a solid option for JK Rubicon owners looking to re-gear their differentials for improved performance with larger tires.
