Description

The USA Standard Gear ZG TV6-373-29 is a ring and pinion gear set engineered to exceed OEM specifications, providing confidence for your vehicle's drivetrain. Each set undergoes rigorous in-house quality evaluation to ensure it passes dimensional, material, and fitment testing, offering a reliable upgrade for common and hard-to-find applications. This specific gear set is designed for Toyota V6 engines and features a 3.73 gear ratio with a 29-spline pinion. It is compatible with a range of Toyota and Lexus models, including the FJ Cruiser (2007-2009), Pickup (1985-1995), Tacoma (1995-2017), T100 (1993-1998), Tundra (2000-2006), 4Runner (1985-2009), and Lexus GX470 (2003-2009). Technical notes indicate that this gear set has a 29-spline pinion, and buyers are advised to verify their pinion spline count prior to purchase. The correct pinion nut part number, YSPPN-025, must be used. USA Standard Gear provides a standard one-year warranty against defects on their ring and pinion sets.
