- 4-Stroke high-compression pistons improve power and torque across entire rpm range
- 4-Stroke big-bore pistons increase engine’s displacement, torque and peak horsepower
- All pistons are heat treated with a T-5 hardening and tempering cycle
- All pistons skirts are coated with a hi-tech molybdenum disulphide (MoS2) coating for faster break-in time and maintain a longer lifespan for the piston
