|High performance turbo racing valve spring kit||88-88050|
|“Shim in tappet” high performance turbo racing valve spring kit||”Shim in Tappet” valve spring kits provide a solution to the common ovaling of retainers and shim spitting in higher performance applications. By locating the shim in the heat treated steel tappet instead of the titanium retainer, wear is greatly reduced, and reliability is increased. These tappets were designed and analysed using the same Finite Element Analysis software used in the development of our valves in order to maintain the same strength and mass as our high performance traditional tappet/retainer system.||88-88100|
