Wiseco 6393LX100 Chevy LS -25cc Dish Forged Piston 4.000 in. Bore Shelf Stock

The Wiseco 6393LX100 is a Professional Series shelf-stock forged piston engineered for the Chevrolet LS engine platform. Featuring a -25cc dish crown and a 4.000-inch bore, this individual left-side piston is purpose-built for serious performance and race engine builds requiring a lower compression, boost- or nitrous-friendly configuration.

Wiseco's Professional Series LS pistons are forged and machined in the USA from 2618 aluminum alloy, delivering the high tensile strength needed to survive heavy-duty and severe-duty race applications. The dish crown design helps reduce the compression ratio, making this piston an excellent choice for forced induction and power adder builds.

Key Features:

• Bore Size: 4.000 in. (standard bore)
• Crown Volume: -25cc dish for reduced compression ratio
• Pin Diameter: 0.927 in.
• Material: 2618 forged aluminum for superior tensile strength
• ArmorGlide? skirt coating reduces operating friction, minimizes noise, and extends skirt and cylinder wall life
• Precision-machined ring grooves with anti-detonation groove for improved ring seal
• Dedicated LS-specific forging with optimized valve pockets and crown design
• Forced pin oiling for reliable lubrication under high-stress conditions
• Shelf-stock availability for fast turnaround on engine builds
