Revolution Gear & Axle 15-23 Toyota 4Runner 8.2in Open Rear Axle 4.88 Ratio Gear Package

This 4.88 ratio gear package from Revolution Gear & Axle is built with precision-cut gears designed for the 8.2-inch open rear axle found in late-model Toyota 4Runners. Choosing a lower gear ratio like 4.88 is a common upgrade when you've installed larger tires, helping to restore lost torque and improve acceleration. This means your 4Runner will feel more responsive, especially when climbing hills or carrying extra weight.

Revolution Gear & Axle uses high-grade steel for their ring and pinion gears, ensuring they can handle the increased stress that comes with larger tires and off-road use. The gear teeth are cut using advanced manufacturing techniques to ensure proper meshing and quiet operation, which is crucial for a comfortable driving experience. This package includes the ring and pinion gear set, along with all the necessary installation components. You'll find everything you need to complete the gear swap, including bearings, seals, and shims, all manufactured to meet strict tolerances for a reliable installation.

When installing a new gear set, it's important to follow the manufacturer's break-in procedure to ensure the gears seat properly and achieve their maximum lifespan. This typically involves a period of moderate driving with specific speed and load limitations, followed by an oil change. This package is a solid option for 4Runner owners looking to optimize their drivetrain for off-road adventures or heavy loads.
