Revolution Gear & Axle Toyota 4Runner/FJ 8.2in Open Rear Axle 4.88 Ratio Gear Package

Revolution Gear & Axle is known for making solid drivetrain components, and this 4.88 ratio gear package for the Toyota 4Runner and FJ Cruiser's 8.2-inch open rear axle is a prime example. If you've upgraded your tires to a larger size, or if you're looking to improve your vehicle's performance off-road or when towing, changing your ring and pinion gears is a smart move. A lower gear ratio like 4.88 helps bring your engine's RPMs back into their power band, making acceleration feel much more responsive and reducing strain on your drivetrain.

This package includes everything you need to get those new gears installed correctly. You'll find the ring and pinion gears themselves, along with a complete installation kit. This kit contains all the necessary bearings, seals, shims, and hardware to ensure a proper setup. Using high-quality components and a precise installation is crucial for the longevity and performance of your differential, and Revolution Gear & Axle aims to make that process as straightforward as possible with their well-put-together kits.

When installing a new ring and pinion set, it's important to follow the manufacturer's break-in procedure. This typically involves a period of gentle driving with no heavy loads or hard acceleration, followed by a specific heat cycle process. This allows the new gear teeth to properly mate and wear in, ensuring a quiet and durable operation for years to come. This package is designed for the 8.2-inch rear axle found in many 4Runners and FJ Cruisers, so double-check your specific vehicle's axle size to confirm compatibility.
