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

Revolution Gear & Axle is known for making solid drivetrain components, and this rear axle gear package for your Toyota 4Runner or FJ Cruiser is a prime example. If you've upgraded your tires to a larger size or are planning to, changing your gear ratio to 4.88 is a smart move. This helps bring your engine RPMs back into their optimal range, improving acceleration and making your vehicle feel more responsive, especially when you're off-road or towing.

This package includes a heavy-duty 8.2-inch rear axle assembly that's built to handle more stress than stock. The real star here is the integrated locker, which allows you to mechanically lock both rear wheels together. This is a game-changer when you encounter low-traction situations, like climbing over rocks or navigating slippery trails, as it ensures both wheels receive power. The 4.88 ratio is specifically chosen to complement larger tire sizes, bringing your cruising RPMs back to a more efficient and comfortable level.

When you're installing a new gear set and axle assembly, it's important to follow the manufacturer's break-in procedure carefully. This typically involves a period of moderate driving with no hard acceleration or heavy loads, followed by an oil change. This process allows the new gears to properly mesh and wear in, ensuring long-term durability and performance. This package is a significant upgrade for serious off-road enthusiasts looking to maximize their vehicle's capability.
