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

This package from Revolution Gear & Axle gives you everything you need to change the gear ratio in your 2007-2018 Jeep Wrangler JK's non-Rubicon differentials to a 4.56 ratio. You'll get the ring and pinion gears, along with a complete set of Timken bearings and installation hardware. Changing your gear ratio is a common upgrade when you install larger tires, helping your Jeep's engine and transmission work together more efficiently. A 4.56 ratio is a popular choice for Wranglers running 35-inch or 37-inch tires, bringing your RPMs back into a more comfortable range on the highway and improving acceleration off the line.

Revolution Gear & Axle sources quality components for their kits. The ring and pinion gears are made from durable steel, heat-treated for strength and longevity. Timken bearings are well-known in the drivetrain world for their solid construction and reliability, ensuring smooth operation and long life for your differential. This kit includes all the necessary installation hardware, such as crush sleeves, pinion nuts, and seals, so you can complete the job without needing to source additional small parts. Proper installation is key for gear sets; it requires careful setup and measurement to ensure the gears mesh correctly and run quietly.

When installing a new gear set, it's important to follow the manufacturer's break-in procedure. This typically involves a period of moderate driving with no hard acceleration or heavy loads, followed by a few heat cycles. This allows the new gear teeth to properly mate and wear in, ensuring optimal performance and longevity. If you're unsure about the installation process, it's always best to consult a professional mechanic or refer to the detailed installation instructions provided with the kit.
