Prox Steel INTAKE Valve/Spring Kit
Prox is offering a wide range of titanium into steel conversion kits. The ProX titanium into steel extends 3

times the lifespan up the OEM titanium valves. The kits contain a set of steel intake or exhaust valves plus a set of special designed stronger valve springs. due to the extra weight of the steel valve a heavier valve spring must be used! The ProX kit just replaces the OEM valves & valve springs and can be installed using the OEM retainers, bases and valve seats.
