- 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.
