• Now you can own the same race parts as all the top race teams
• 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.
