High-Performance Piston Kit

WISECO
AF6C310B-3737-4852-8EF4-82AF7DDEABDC.png
  • 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
  • Features forged pistons, rings, wrist pins, and circlips
  • 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
  • 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
  • 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.
