These high-tech piston designs offer maximum compression ratios, ultra-stiff strutted forgings, and titanium nitride-coated rings, which all add up to more power that is sustained longer
When blow-by starts to increase on other pistons and power starts to fade, Wiseco Race Series parts continue sealing and performing
Have additional features over standard Pro-Lite parts
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
Additionally, boost ports are removed for a more predictable powerband and increased pull on the top end
Service intervals may be increased with Racer's Choice pistons over conventional Wiseco pistons, and are for expert racers and tuners only.
