The Wiseco K451X7 is a Professional Series forged piston set engineered for high-performance Chevy LS-based engines.

Key Features:

• 2618 Forged Aluminum Construction — Engineered, forged, and machined in the USA for superior tensile strength; will not shatter like hypereutectic or cast pistons

• Dedicated LS Forgings — Features specially designed valve pockets, optimized skirt profiles, and precision-machined ring grooves specific to the LS platform
• Anti-Detonation Groove — Helps keep the top ring groove free of carbon buildup and improves detonation resistance
• Pressure Groove — Enhances ring seal performance under high-boost and nitrous applications
• Reluctor Ring Clearance — Designed to accommodate the reluctor ring on stroker cranks without requiring notching of the pin bosses
• Radiused Valve Pockets — Improve airflow around valves and increase resistance to detonation
• GFX Ring Pack Included — Comes with a 1.2mm nitride steel top ring, 1.2mm Napier 2nd ring, and 3.0mm nitride oil ring for optimal sealing, reduced friction, and superior oil control
• Chrome Moly Wrist Pins & Spirolox® — Included in the kit; tool steel pins available as an upgrade
• Multi-Fit Valve Pockets — Allow for interchangeability across a range of cylinder heads
• Race-Ready Dome Finish — Domes are finished and deburred at the factory, requiring no additional preparation by the engine builder
