Wiseco WIS-15972 Custom Forged Single Piston

The Wiseco WIS-15972 is a custom-specification forged piston engineered to meet precise performance and fitment requirements. Wiseco's custom piston program allows builders to specify critical dimensions — including bore diameter, compression height, pin diameter, and dome or dish configuration — ensuring an exact match to their engine's unique specifications.

Wiseco pistons are manufactured from high-strength 2618 or 4032 aluminum alloy forgings, delivering an optimal balance of strength, thermal expansion control, and weight. Each piston is CNC-machined to tight tolerances, making them a preferred choice among professional engine builders for racing, high-performance street, marine, and powersports applications.

Key Features:

• Custom-specification design built to individual builder requirements
• Forged aluminum construction for superior strength-to-weight ratio
• CNC-machined to tight tolerances for precise fit and reliable sealing
• Compatible with Wiseco piston rings and wrist pins (sold separately)
• Suitable for high-performance, racing, and specialty engine builds
• Available in a range of bore sizes, compression heights, and dome configurations upon specification
• Manufactured in the USA by Wiseco Piston Co.

As a custom-order component, the WIS-15972 is built to the purchaser's specified dimensions and configuration. Confirm all critical measurements with your engine builder prior to ordering to ensure proper fitment and performance.
