WSM Platinum Series Piston Kit Standard Size for Polaris 400

Elevate your engine's performance and longevity with the WSM Platinum Series Piston Kit Standard Size. Engineered to meet or exceed OEM specifications, this kit provides a robust and reliable foundation for your Polaris 400 1994-1996 engine rebuild or upgrade.

Description

Designed for discerning riders and mechanics, the WSM Platinum Series Piston Kit delivers exceptional quality and performance. Each WSM Platinum Series Piston Kit Standard Size is crafted to meet or exceed original equipment manufacturer (OEM) standards, ensuring a precise fit and reliable operation. A key innovation is the advanced MoS2 (Molybdenum Disulfide) coating applied to the piston skirts. This non-abrasive, expansion-retarding layer significantly reduces heat and friction within the cylinder, translating to enhanced power output and considerably extended engine life. The MoS2 coating also actively draws heat away from the piston walls, optimizing thermal management. Furthermore, the piston tops feature a specialized hardening process, providing superior strength to the ring grooves, crucial for maintaining consistent compression and preventing premature wear. With an improved E-clip design, installation is straightforward, contributing to a secure and durable assembly. This kit is specifically compatible with Polaris BIG BOSS 400 6X6 L and SPORT 400 L 2x4 models from 1994-1996, making it an ideal choice for restoring or upgrading your Polaris 400 piston.
