PISTON KITS, RINGS,
WRIST PINS AND CIRCLIPS
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
Big Bore pistons increase engine’s displacement, torque, and peak horsepower
Forged Replica pistons are forged OE replacements
Replica pistons and all rings are OEM replacements
Kits include piston, rings, wrist pin
and circlips
