    • 2618 Alloy Fully CNC Machined Piston with performance skirt coating
    • Black Diamondtm Stainless Steel conversion system significantly increases valve durability
    • Lightweight Racing Spring Kit compatible with high performance cams
    • All of the gaskets, rings, pins and seals required for a top end rebuild
    • Includes Piston, Rings, Clips and Pin

    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 Diamondtm Stainless Steel Valves offers up to double the life over stock Titanium valves without a loss in performance.
