Dedicated forging design for strength-to-weight optimization
Extra lightening operations for enhanced throttle response
Engineered, forged, and machined in the USA
Piston is made in the USA
Each piston is E-Coated on the crown, ring grooves, and pin bore, for maximum wear resistance and protection from micro-welding, galling, and detonation
GP Series parts generally have less machining on the outside, which helps seal up the bore for increased compression
Cylinder sleeves must be purchased separately.
Service intervals may be increased with Racer's Choice pistons over conventional Wiseco pistons, and are for expert racers and tuners only.
Additionally, boost ports are removed for a more predictable powerband and increased pull on the top end
