Supertec Racing Billet Spline Drive Gear kits for Toyoya UZ-FE engines.
Spline drive engagement provides full 360 degree rotational support and prevents breaking of the inner gear as is so often found with the factory flat drive setup. Gear and collars are made of billet steel (41CR4) featuring wave tooth design for optimal flow.
Will fit all UZ-FE series from 1-3 with the use of the later VVTi pump - 3 piece setup consisting of inner and outer gears and collar.
Used by Japanese Drift teams inclucing Do-Luck Racing on their 1200hp Supra with 3UZFE engine.
