Wiseco SK1028 Forged Snowmobile Piston Kit for Ski-Doo

The Wiseco SK1028 is a high-performance forged snowmobile piston kit engineered specifically for Ski-Doo engines. Wiseco's legacy in 2-stroke piston manufacturing spans over 80 years, and today their snowmobile pistons represent decades of experience incorporating the latest in 2-stroke piston design and manufacturing technology.

Engineered, forged, and machined in the USA in Mentor, OH, each piston is designed and built for a specific 2-stroke powersports engine to ensure an optimized fit and maximum performance.

Why Forged Pistons?

Forged pistons offer a decisive advantage over cast alternatives. Forgings feature a condensed, aligned grain structure that produces superior mechanical properties, greater resistance to impact, and improved fatigue life. Cast pistons, by contrast, lack defined grain structure and can fail catastrophically when material yield strength is exceeded — a risk unacceptable in high-performance snowmobile applications.

Kit Contents & Features:

• Kit includes forged piston, rings, wrist pin, and circlips
• Forged from high-silicone bar stock for greater strength and lower thermal expansion at elevated temperatures
• Dedicated forgings with lightening operations optimize the strength-to-weight ratio
• Skirt coating applied for reduced friction and improved break-in
• Designed for snocross and cross-country racing demands
• Priced with rings, wrist pins, and circlips included — note that Wiseco rings fit Wiseco pistons only and ring types are not interchangeable

Cylinder sleeves must be purchased separately. The Wiseco SK1028 is the ideal choice for riders rebuilding or overboring their Ski-Doo top end and demanding OEM-beating durability from every component.
