The Wiseco 83.00 mm piston kit for Polaris 400 ATV (model number 675M08300) is engineered for enthusiasts seeking maximum performance and durability. Forged from high-silicon aluminum alloy, this piston provides exceptional strength and dependability, making it suitable for both trail riding and racing applications. The innovative forging design and piston skirt construction maximize horsepower and torque, ensuring that your ATV delivers reliable power over extended periods of intense use.
Featuring forged pistons, rings, wrist pins, and circlips, this kit is built to withstand the rigors of high-performance riding. The advanced piston design allows for increased compression ratios, which translates into more power and efficiency. Additionally, the ultra-stiff strutted forgings and titanium nitride-coated rings contribute to improved wear resistance and sustained power output.
Each piston is E-coated on the crown, ring grooves, and pin bore to provide maximum protection against micro-welding, galling, and detonation, extending the lifespan of the components. The GP series design minimizes external machining, helping to enhance sealing for increased compression and overall engine efficiency. The removal of boost ports results in a more predictable powerband and increased pull on the top end, ideal for performance tuning. Cylinder sleeves are sold separately and should be considered when installing this piston kit. This product is suited for expert racers and tuners aiming to push their ATV's performance to the limit, with potential for increased service intervals compared to standard Wiseco pistons.
