Wiseco Piston Kit 1mm Oversize for Polaris 400 1995-2003

Elevate your Polaris 400's engine performance with the Wiseco 1mm Oversize Piston Kit. Designed for demanding trail and racing applications, this high-performance kit ensures superior durability and increased power output.

Description

The Wiseco 1mm Oversize Piston Kit is meticulously engineered for the Polaris SCRAMBLER 400 4X4 and XPLORER 400 4X4 models from 1995-2003, providing an essential upgrade for riders seeking uncompromising engine reliability and performance. Each piston is precision-forged from a high-silicon aluminum alloy, a material renowned for its exceptional strength and dependability under extreme conditions. This robust construction ensures superior longevity and a significant boost in horsepower and torque, making it ideal for both aggressive trail riding and competitive racing. The innovative forging design, combined with a specialized piston skirt, optimizes power delivery across the RPM range. Furthermore, these high-tech piston designs feature maximum compression ratios and ultra-stiff strutted forgings, complemented by titanium nitride-coated rings for sustained power. Every piston undergoes an E-coating process on the crown, ring grooves, and pin bore, offering maximum wear resistance and protection against micro-welding, galling, and detonation. As a GP Series part, it benefits from less external machining, which enhances bore sealing for increased compression, while the removal of boost ports contributes to a more predictable powerband and stronger top-end pull, ensuring your Polaris 400 performs at its peak.
