Supertec Racing Spline kits for Nissan RB26 and 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.
