Speed-Pro Kits provide perfectly matched pistons and rings.

These Speed-Pro piston and ring kits include hypereutectic pistons (except where noted) and a set of matching moly-faced piston rings. The hypereutectic pistons are made from aluminum alloy with over 16 percent silicon content for strength and durability. They are precision diamond machined to run with traditional ring end gaps for maximum power and oil control, and a Dur-O-Shield coating reduces friction and eliminates scuffing and wear. Matching piston rings are included.
