PRODUCT INFORMATION
The RIVA Super-Duty GEN-4 Supercharger Shaft Kit strengthens the supercharger on Yamaha 1.8L SHO and SVHO engines for high-boost use. A hydraulic stabilisation bearing supports the end of the shaft on a high-pressure oil film to limit deflection and wear, fed by a through-shaft oiling system and a braided stainless line into a billet end cap.
The shaft, collar and gear are machined as one piece from high-strength billet steel, removing the stock weak point where the gear is pressed on. Larger threads and nut, and a new one-piece bearing with more surface area, add strength. It is a direct bolt-on replacement for OEM parts with no machining, made exclusively for RIVA by HKS.
