Kit Includes:

• 2x Circlips #CW18

• 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.
