TOP END PISTON KITS
All pistons are heat-treated with a T-5 hardening and tempering cycle
All piston skirts are coated with a high-tech Molybdenum Disulphite 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 OEM replacements
Replica pistons and all rings are OEM replacements
Top end piston kit includes piston, rings, pins, circlips, top end gaskets, wrist pin bearing when applicable and cam chain when applicable
