Product Description

The Revolution Gear & Axle T8-488V6-29 ring & pinion set is engineered for Toyota 8.0" differential applications in trucks and SUVs with turbo 4-cylinder or V6 engines. With the 4.88:1 ratio and a 29-spline pinion design, this gear set delivers improved torque delivery, reliable operation under load, and a strong upgrade for both off-road and highway use.

Manufactured from heat-treated 8620 alloy steel and precisely cut for smooth engagement, this ring & pinion set simplifies installation when the housing retains the stock configuration. Ideal for models such as the Tacoma, FJ Cruiser and GX470 running the Toyota 8.0" diff, the T8-488V6-29 is built to perform.

Please note: Fitment is confirmed for 2003-2023 Toyota Tacoma, 2007-2014 Toyota FJ Cruiser, and 2003-2009 Lexus GX470, all with Toyota 8.0" differential and Turbo 4-Cyl or V6 engines. Coverage beyond these years and for all trims is **unconfirmed at time of listing**. Always verify your axle housing, spline count, differential rotation (standard vs reverse), and compatibility before installation.
