Revolution Gear & Axle 15-23 Toyota 4Runner 8.2in Rear Axle w/Locker 4.56 Ratio Gear Package

This 4.56 ratio gear package from Revolution Gear & Axle includes a selectable locker and is built for the 8.2-inch rear axle found in 2015 through 2023 Toyota 4Runners. Choosing a lower numerical gear ratio like 4.56 is a common upgrade when you've added larger tires, as it helps bring your engine's RPMs back into a more efficient range at cruising speeds. This means better acceleration and less strain on your drivetrain, especially noticeable when towing or climbing hills.

The selectable locker is a key feature here, allowing you to engage it when you need maximum traction, like on challenging off-road trails or in slippery conditions. When not engaged, it functions like a standard open differential, which is better for on-road handling and tire wear. Revolution Gear & Axle is known for well-built drivetrain components, and this package is designed to integrate seamlessly with your vehicle's existing setup, assuming it has the 8.2-inch rear axle. This kit includes the gears and the locker, but you'll want to ensure you have a complete differential installation kit on hand, which typically includes bearings, seals, and shims, to properly set up the new ring and pinion gears.

Proper installation is crucial for the longevity and performance of any gear change. It's highly recommended to have this package installed by a professional mechanic experienced with differential setups, as precise setup of the ring and pinion is critical. This ensures smooth operation, prevents premature wear, and maximizes the benefits of the new gear ratio and locker.
