Wiseco Pistons 4670M06750 67.50mm ATV Piston Kit - 2mm Oversized

The Wiseco 4670M06750 is a high-performance forged piston kit designed for ATV applications requiring a 67.50mm bore (2.00mm oversized). This complete piston kit delivers the strength and durability demanded by aggressive riding conditions and performance builds.

Key Features:

• Complete piston kit includes piston, rings, wrist pin, and circlips
• Forged in-house in the USA for superior strength and quality control
• 67.50mm bore size (2.00mm oversized from stock)
• Stock compression ratio design for reliable performance
• Condensed grain structure aligned to part features for maximum impact and fatigue resistance
• Optimized strength-to-weight ratio for improved throttle response
• Skirt coating applied for reduced friction and extended cylinder life

Wiseco's forging process creates pistons with superior mechanical properties compared to cast alternatives. The aligned grain structure resists catastrophic failure under high-stress conditions, making these pistons ideal for performance rebuilds and big bore applications. Each piston is precisely machined to exacting tolerances for proper ring seal and long-term reliability.

Fitment: Compatible with Arctic Cat DVX 400 2x4 (2004), Kawasaki KFX400 (2003-2006), and Suzuki LTZ400 QuadSport (2003-2008) when bored 2.00mm oversize.
