Wiseco 6454RX05 Professional Series Chevy LS Forged Piston -14cc Reverse Dome 4.005 in. Bore

The Wiseco 6454RX05 is a Professional Series shelf-stock forged piston engineered for Chevrolet LS series engines. Featuring a -14cc reverse dome (R/Dome) crown and a 4.005 in. bore diameter, this single piston is purpose-built for high-compression, high-performance LS builds where precise combustion chamber volume control is critical.

Wiseco's Professional Series represents a no-compromise approach to piston design — engineered, forged, and machined in the USA at Wiseco's Mentor, Ohio facility from 2618 high-strength aluminum alloy, delivering the tensile strength and fatigue resistance demanded by serious racing and power-adder applications.

Key Features:

• -14cc Reverse Dome Crown: Precision-machined R/Dome profile for elevated compression ratios in LS applications
• 4.005 in. Bore Diameter: Shelf-stock sizing for standard and mildly oversized LS bores
• 2618 Aluminum Alloy: High-strength forging material optimized for performance and power-adder use
• ArmorGlide® Skirt Coating: Reduces operating friction, minimizes skirt and cylinder wall wear, and quiets piston operation
• Fully Machined Crown Features: Precision-machined valve pockets and combustion surfaces for consistent performance
• Precision Ring Grooves: Anti-detonation groove and ring seal features for maximum cylinder pressure retention
• Forced Pin Oiling: Maintains optimal wrist pin and small-end lubrication for long service life
• Shelf Stock Availability: Ready-to-ship single piston for engine builders sourcing individual replacements or building custom combinations

Sold as a single piston. Compatible with Wiseco's X-series GFX 1.2/1.2/3.0mm steel top/Napier 2nd ring sets. Ideal for LS engine builds targeting increased compression, forced induction, or nitrous applications.
