Wiseco 6662M86AP Professional Series Forged Piston Bore - 86mm

The Wiseco 6662M86AP is a Professional Series forged racing piston with an 86.00mm bore diameter, engineered for high-performance and race-duty automotive engine builds. Wiseco's Professional Series represents their no-compromise line of pistons, designed for serious engine builders and racers who demand maximum durability and performance under heavy to severe duty conditions.

Key Features:

• 86.00mm Bore Diameter — precision-machined to tight tolerances for optimal cylinder fit
• Forged 2618 Aluminum Construction — superior tensile strength and fatigue resistance compared to cast pistons
• ArmorGlide® Skirt Coating — reduces friction, resists seizure, and enables quieter operation
• Deep Valve Pockets — provides generous valve-to-piston clearance for aggressive camshaft profiles and modified cylinder heads
• CNC Diamond-Turned Finish — guarantees precise sizing with no variation across the piston set
• Offset Pin Design — reduces piston slap for quieter, smoother engine operation
• Includes Matched Ring Set and Wrist Pin — complete kit for a full piston installation
• Engineered, Forged, and Machined in the USA — manufactured at Wiseco's Mentor, Ohio facility

Wiseco's Professional Series pistons are built for heavy to severe duty race applications where stock or standard performance pistons fall short. The combination of 2618 forged aluminum, ArmorGlide skirt coating, and precision CNC machining makes the 6662M86AP a reliable foundation for high-boost, high-RPM, or nitrous-assisted builds. Always verify bore size, compression height, and rod dimensions against your specific engine specifications prior to installation.
