Wiseco 6445RXS Chevy LS Series Forged Shelf Stock Piston -15cc Reverse Dome

The Wiseco 6445RXS is a shelf-stock, single forged piston engineered specifically for the Chevrolet LS Series engine platform. Featuring a -15cc reverse dome (R/Dome) crown design, this piston is precision-machined to deliver the compression characteristics demanded by high-performance and racing LS builds. As a shelf-stock unit, it ships individually — ideal for replacement or custom odd-cylinder builds.

Key Features:

• -15cc Reverse Dome Crown: Optimized dome volume for tunable compression ratios in LS performance applications
• Forged 2618 Aluminum Construction: Engineered and forged in the USA from high-strength 2618 alloy for superior tensile strength and fatigue resistance under heavy and severe-duty race conditions
• ArmorGlide® Skirt Coating: Factory-applied skirt coating reduces operating friction, minimizes skirt and cylinder wall wear, and promotes quieter operation
• 1.110 in. Compression Height: Designed for proper deck clearance in standard and stroked LS builds
• 0.927 in. Pin Diameter: Compatible with standard LS wrist pin dimensions
• Shelf Stock (Single Piston): Ready to ship individually — no special order required
• Professional Series Quality: No-expense-spared design built for serious racers and engine builders

Wiseco's LS series pistons are engineered, forged, and machined entirely in the USA, making them a trusted choice for drag racing, circle track, and power adder applications. The 6445RXS delivers the strength, precision, and durability required for demanding Chevy LS performance builds.
