Wiseco 6396RX05 Chevy LS Forged Piston -32cc Dish 4.005 in. Bore Shelf Stock

The Wiseco 6396RX05 is a Professional Series shelf-stock forged piston designed for the Chevrolet LS engine family. Featuring a -32cc dish crown and a 4.005 in. bore size, this single piston is precision-engineered for high-performance street and race builds that demand reliable compression tuning and long-term durability.

Key Features:

• 2618 forged aluminum construction — engineered, forged, and machined in the USA at Wiseco's Mentor, Ohio facility for superior tensile strength over cast or hypereutectic alternatives
• -32cc dish crown — optimized for precise compression ratio tuning on LS platform builds
• 4.005 in. bore diameter — fits standard LS bore dimensions with shelf-stock availability for immediate use
• 0.927 in. wrist pin diameter — consistent with Wiseco's LS series pin specification
• ArmorGlide® skirt coating — reduces operating friction, minimizes skirt and cylinder wall wear, and quiets piston operation
• Precision ring grooves with anti-detonation groove and additional ring seal features for improved sealing integrity
• Forced pin oiling — horizontal slot oiling in pin bores maintains optimal wrist pin and small-end lubrication
• Fully machined crown features — radiused valve pockets improve detonation resistance and increase flow around valves
• Strutted skirt design engineered for minimal piston rock and excellent wear characteristics

Wiseco's Professional Series shelf-stock pistons are built for serious engine builders who need competition-grade components readily available. The 6396RX05 is sold as an individual piston, making it ideal for single-cylinder replacement or custom set builds on the Chevrolet LS platform.
