Toyota FJ and 4Runner 8.2 Inch Rear Axle with Locker 4.88 Ratio Gear Package Revolution Gear

Boost your off-road confidence with the 1st Gen FJ Cruiser 4.88 Gear by Revolution Gear and Axle. Designed specifically for Toyota FJ Cruiser models equipped with a factory locker, this package transforms how your rig performs on rough trails or with oversized tires. Whether you’re towing a trailer, climbing rocks, or heading out on a highway journey, this 4.88 gear ratio delivers the perfect balance of torque and drivability.

Because larger tires often reduce low-end performance, this re-gear option helps reclaim lost torque and enhances throttle response. Additionally, it helps keep engine RPMs in the sweet spot while cruising, which means you burn less fuel over time. Moreover, smoother power delivery ensures that your rig stays in control no matter the terrain. As a result, you’ll enjoy longer trips with fewer compromises.
