Product Description

The Revolution Gear & Axle T8-488R-29 ring & pinion set is engineered specifically for Toyota 8.0" reverse-rotation differential setups. With a 4.88 :1 gear ratio and 29-spline pinion design, it delivers improved torque delivery, especially useful when off-roading, towing, or restoring older Land Cruiser and Lexus IFS front-diff applications.

Constructed from heat-treated 8620 steel, this gear set is built for durability, quiet operation and precise engagement. Installers will appreciate that no carrier break is required in many cases when the OEM housing and spec are retained. If you're rebuilding the front differential on your Land Cruiser 80/100 series, LX450 or LX470 with the Toyota 8.0" front gear housing and need the correct 29-spline reverse-rotation 4.88 gear set, the T8-488R-29 is a direct-fit aftermarket upgrade engineered for that purpose.

Please note: Fitment is confirmed for 1990-2007 Toyota Land Cruiser, 1996-1997 Lexus LX450, and 2003-2007 Lexus LX470 (all 4WD with Toyota 8.0" reverse-rotation differential). Coverage beyond 2007 and any 2008-2025 models is **unconfirmed at time of listing**. Always verify your axle housing, spline count and rotation direction before installation.
