Wiseco SK1382 Piston Kit for Polaris Snowmobile STD Bore

The Wiseco SK1382 is a forged piston kit engineered for Polaris snowmobiles, built to withstand the extreme demands of snocross and cross-country racing. Wiseco has spent decades developing snowmobile-specific forged pistons right here in the USA, and this kit reflects that deep motorsport expertise.

American-Made Forged Construction:

• Forged entirely in-house using Wiseco's own proprietary forge tooling
• Full manufacturing control from raw bar stock to finished skirt coating
• In-house dyno testing ensures real-world performance validation
• Standard (STD) bore sizing for direct OEM replacement

Why Forged Outperforms Cast:

• Condensed, aligned grain structure delivers superior mechanical properties
• Greater resistance to impact and fatigue compared to brittle cast pistons
• Forgings deform under stress rather than failing catastrophically like castings
• Optimized strength-to-weight ratio for maximum power output

Performance Engineering:

• Skirt coating reduces friction and improves break-in
• Designed using advanced shape and coating technology developed through rigorous R&D
• Built to handle the abuse of high-performance motorsport applications

The Wiseco SK1382 piston kit is the choice for Polaris snowmobile owners who demand OEM-quality fit with race-proven forged performance. Whether you're rebuilding a trail sled or prepping for competition, Wiseco's vertically integrated manufacturing process ensures consistent quality from every kit.
