Upgrade your Polaris 400 4X4 engine with the high-performance Wiseco GP Series 400 Piston Kit, engineered for maximum power and reliability. This kit provides a significant boost in durability and horsepower for your SCRAMBLER 400 4X4 or XPLORER 400 4X4 models from 1995-2003.

Description

Experience unparalleled engine performance and longevity with the Wiseco GP Series Piston Kit. Each piston is meticulously forged from a high-silicon aluminum alloy, ensuring exceptional strength and dependability under the most demanding conditions. This advanced construction translates directly into increased horsepower and torque, delivering a more responsive and powerful ride. Wiseco's innovative forging design and optimized piston skirt work in harmony to maximize power output, while the high-tech design allows for maximum compression ratios and features ultra-stiff strutted forgings for sustained performance. Critical components like the titanium nitride-coated rings enhance durability and reduce friction, ensuring your engine runs stronger for longer. Furthermore, each piston is E-Coated on the crown, ring grooves, and pin bore, providing superior wear resistance and protection against micro-welding, galling, and detonation. The GP Series specific design, with less machining on the outside, enhances bore sealing for increased compression, and the removal of boost ports contributes to a more predictable powerband and increased pull on the top end, making this an ideal choice for serious riders and tuners.
