All piston skirts are coated with a hi-tech Molybdenum Disulphite coating for faster break-in time and increased piston life
Cast Replica piston kits are gravity cast aluminum alloy (not forged) with 18% silicone content, which produces an extremely light but very strong piston
Forged Replica pistons are forged from 2618 aluminum for superior strength and durability
Forged High Compression pistons improve power and torque across entire rpm range
Forged Big Bore pistons increase engine's displacement, torque, and peak horsepower
Forged Replica pistons are forged OE replacements
All pistons are heat treated with a T-5 hardening and tempering cycle
Replica pistons and all rings are OEM replacements
Kits include piston, rings, wrist pin and circlips
Two stroke replacement rings are sold individually (Example if your piston has two rings you will want to order two rings)
Four-stroke piston rings sold as a set
