The WISECO Piston Kit is designed for Polaris 400 ATV applications and features an 84.00 mm piston size. Manufactured from forged high-silicon aluminum alloy, this kit is engineered for strength, dependability, durability and sustained performance. The piston design supports increased horsepower and torque, while the innovative forging and piston skirt help maximize power delivery.
This WISECO kit features a forged piston, rings, wrist pin and circlips. It uses a high-compression piston design with an ultra-stiff strutted forging and titanium nitride-coated rings. Each piston is E-Coated on the crown, ring grooves and pin bore to improve wear resistance and help protect against micro-welding, galling and detonation. GP Series parts generally use less machining on the outside to help seal the bore for increased compression, while the boost ports are removed for a more predictable powerband and increased pull on the top end.
