The WISECO Piston Kit is designed for Polaris 400 ATV applications and features an 83.00 mm piston size. Forged from high-silicon aluminum alloy, this kit is engineered for strength, dependability, durability, longevity, and increased horsepower. Its forging design and piston skirt support increased horsepower and torque.
The kit features a forged piston, rings, wrist pin, and circlips. The piston design supports high compression ratios and uses an ultra-stiff strutted forging. Titanium nitride-coated rings contribute to sustained power. The piston crown, ring grooves, and pin bore are E-Coated for wear resistance and protection from micro-welding, galling, and detonation.
GP Series components generally use less machining on the outside to help seal the bore for increased compression. Boost ports are removed for a more predictable powerband and increased pull on the top end. Cylinder sleeves must be purchased separately. Racer's Choice pistons are intended for expert racers and tuners only and may allow increased service intervals compared with conventional WISECO pistons.
