Wiseco SK1167 Pro-Lite Forged Snowmobile Piston Kit

The Wiseco SK1167 is a forged snowmobile piston kit engineered for the rigorous demands of snocross and cross-country racing. Built entirely in the USA, this Pro-Lite piston is part of Wiseco's race-proven lineup of performance powersports pistons.

Wiseco is one of the few manufacturers that forges all of its own pistons in-house and produces all of its own forge tooling domestically. This end-to-end control over the manufacturing process — from raw bar stock through skirt coating — ensures consistent quality and enables rapid development of cutting-edge piston technology.

Key Features:

• Forged aluminum construction — delivers superior toughness, impact resistance, and fatigue strength compared to cast pistons
• Condensed, aligned grain structure — enhances mechanical properties and resistance to catastrophic failure under extreme load
• Optimized strength-to-weight ratio — dedicated forgings engineered to maximize performance without unnecessary mass
• Skirt coating applied in-house — reduces friction and wear for extended service life
• USA-manufactured — forged and machined at Wiseco's facility in Mentor, Ohio
• In-house dyno tested — validated through rigorous R&D to meet the demands of competitive snowmobile racing
• Kit includes piston, ring set, wrist pin, and circlips

Unlike cast pistons, which are brittle and prone to sudden failure when material yield strength is exceeded, Wiseco forgings feature a dense grain structure aligned to the geometry of the part. This produces higher mechanical properties and greater resistance to the shock and fatigue loads generated in high-performance snowmobile engines. The SK1167 is a proven choice for snocross competitors and performance enthusiasts who demand reliability under extreme conditions.
