The PROX Exhaust Valve Conversion Set Ti Steel Kaw provides an alternative to applications that use titanium valves. This kit includes steel valves and specially designed stronger valve springs, offering increased durability and reduced wear under extreme conditions.
The valves feature a nitrided finish for high microhardness and a smooth surface that helps reduce friction between the valve stem and guide. The springs are made from premium chrome vanadium steel and are designed to handle the additional weight of steel valves while supporting performance and durability at high RPMs.
The PROX kit replaces the OEM valves and valve springs and can be installed using the OEM retainers, bases and valve seals. It is designed as a complete package for a quick, easy and cost-efficient replacement without further engine modifications. Part number 28.SES4409-1.
