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.
• Forged pistons are forged from 2618 aluminum for superior strength and durability.
• Forged High Compression pistons improve power and torque across entire rpm range.
• Forged Replica pistons are forged OE replacements
• All pistons are heat treated with a T-5 hardening and tempering cycle.
• Replica KTM 2-stroke pistons are factory supplied to KTM
• All rings are OEM replacements.
• Top end piston kit includes piston, rings, pins, circlips, top end gaskets, and wrist pin bearing or cam chain where applicable.
