Features:

• New T-box forgings and DLC coated wrist pins on forged pistons with highest compression ratios for increased strength and performance.
• All piston skirts are coated with a high-tech Molybdenum Disulfide coating for faster break-in time and increased piston life
• Cast piston kits are gravity cast aluminum alloy (not forged) with 18% silicone content, which produces an extremely light but very strong piston.
• All pistons are heat treated with a T-5 hardening and tempering cycle.
• Top end piston kit includes piston, rings, pins, circlips, top end gaskets, and wrist pin bearing or cam chain where applicable.
• All rings are OEM replacements.
