Forged from high-silicon aluminum alloy for maximum strength and dependability

Wiseco offers a complete range of popular piston models and years for both trail and racing applications

Durability, longevity and increased horsepower

Innovative forging design and piston skirt provide maximum horsepower and torque

Feature forged pistons, rings, wrist pins, and circlips

Cylinder sleeves must be purchased separately

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

Service intervals may be increased with Racer's Choice pistons over conventional Wiseco pistons, and are for expert racers and tuners only.

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
