Revolution Gear & Axle 07-18 Jeep Wrangler JK Non-Rubicon Koyo Bearing 4.88 Ratio Gear Package

If you've upgraded your Jeep Wrangler JK to larger tires, changing your differential gear ratio is essential for getting back that lost performance. This Revolution Gear & Axle package is built for 2007-2018 Jeep Wrangler JK models that are NOT equipped with the factory Rubicon package, and it includes a 4.88 ratio gear set along with Koyo bearings. Going to a 4.88 ratio is a popular choice for JK owners running 35-inch to 37-inch tires, as it helps bring your engine's RPMs back into a more efficient range at highway speeds, improving acceleration and drivability.

Revolution Gear & Axle sources quality components, and this kit features a precision-cut ring and pinion gear set designed for durability. The inclusion of Koyo bearings is a notable detail; Koyo is a well-respected manufacturer known for producing robust bearings that can handle the increased loads and heat generated by re-geared differentials. This package aims to provide a complete solution for re-gearing your non-Rubicon JK's front or rear differential, ensuring smooth power transfer and reliable operation. Proper installation is critical for the longevity of your new gears, so be sure to follow the manufacturer's break-in procedure carefully.

This kit is designed to give your Jeep Wrangler JK the proper gearing for larger tires, making your daily driving and off-road adventures more enjoyable. It's a significant upgrade that addresses the performance impact of larger tire sizes. Remember that this kit is for non-Rubicon models; Rubicon models have a different differential setup and require a different gear ratio package.
