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.
