Top End Service Kit Ss Valve Conversion W/springs

These pistons have been designed to incorporate a domed piston deck, resulting in a high compression profile and offsetting any change in volume caused by valve dishes.While maintaining compression through piston shape, we’ve minimized moving mass in our stainless steel valvetrain conversion by lightening our steel valves.The conversion to black diamond™ stainless steel valves offers up to double the life over stock titanium valves without a loss in performance.
