Supertec Racing Spline kits for Nissan RB, Toyoya UZ-FE and 2JZ engines.

A known weak point with RB engines causing stock flat drive engagement gears to crack or shatter, we undertook 18 months of extensive R&D during 2012-2013 to develop a robust and efficient solution for the Nissan’s RB series of engines. Several spline profiles were tested and analysed on mule engines with varying levels of engine performance from 400hp to 1200hp RB30’s and up to 12000rpm. 

From our testing and analysis data we have the most efficient and durable spline solution in the market today, as well as offering kits for almost all known RB oil pump from N1,Nismo, OEM to Jun, Greddy, Nitto, HKS, Tomei and our own N1 high flow conversion kit - We are a step ahead of our competitors - many of who have only start to offer iterations of a spline concept in the past 2 years. 

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. 

Today our kits are used extensively through out the world, we also manufacture 2JZ kits exclusively for Do-Luck Racing in Japan and we also supply to Tomei Japan as required for their customer Genesis builds.
