Product Description

The Revolution Gear & Axle TLC-488 Ring & Pinion Set provides a 4.88:1 final drive ratio for Toyota Land Cruiser 9.5" rear differentials. It is ideal for increasing torque, accommodating larger tires, or upgrading drivetrains for off-road and towing applications. Precision-cut, heat-treated 8620 steel ensures durability and reliable performance.

Fitment is confirmed for 1963 through 1997 Toyota Land Cruiser models with the 9.5" rear axle housing in a 4WD configuration. Installation requires differential cover removal, correct pinion preload, carrier shim adjustment, and gear mesh verification. This set is not universal; proper setup is necessary for optimal performance.

Before installation, verify your vehicle's rear axle housing, pinion spline count, and ring gear diameter. Fitment beyond 1997 is unconfirmed at the time of listing. Professional installation is recommended to ensure correct alignment, quiet operation, and long-term durability.
