NAMURA FORGED PISTON STD
Namura Forged pistons offer dyno-proven gains in performance and durability over industry-standard 4032 forged pistons. Namura's exclusive forged alloy offers lower expansion rates, allowing for tighter build tolerances and superior tensile and yield strength at operating temperatures.
All new Forged pistons come with Namura's signature features: 100% CNC-machine piston domes, hard anodized domes for reduced carbon build-up and heat resistance and M0S2 coated skirts for excellent break-in protection and properties.
Also available in Top End Repair (T.E.R.) Kits that includes all gaskets, seals and needle bearings (where applicable) needed to complete an engine rebuild. From the crankcase to cylinder head, Namura T.E.R Kits include many components that most competitors don't.
