Product description
Pro-HC – Forged piston developed with Vertex technology and high compression
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
Forged High Compression pistons improve power and torque across entire rpm range
Due to the higher compression, power and torque can be improved across entire rpm range
