Wiseco K0426X2 Chevy LS 3.900 Stroker Forged Piston Kit with .927 Pin

The Wiseco K0426X2 is a Professional Series forged piston kit designed for Chevrolet LS 3.900-inch stroker engine builds. Forged in-house from 2618 high-tensile-strength aluminum alloy at Wiseco's Mentor, Ohio manufacturing facility, these pistons deliver the strength and durability required for power-adder and high-performance race applications.

Key Features:

• ArmorGlide skirt coating — reduces friction, resists seizure, and enables tighter piston-to-wall clearances for quieter operation
• .927 in. (H13 tool steel) wrist pins — premium hardened pins included for maximum durability under high loads
• 1.165 in. compression height — optimized for 3.900 in. stroker crank combinations
• GFX ring pack included — 1.2mm / 1.2mm / 3.0mm ring set engineered for power-adder applications
• Precision ring grooves with anti-detonation groove and additional ring seal features
• Forced pin oiling for enhanced lubrication at high RPM
• Fully machined crown features for precise combustion chamber geometry

Built for serious racers and high-performance engine builders, the Wiseco K0426X2 Professional Series kit provides custom-level performance and durability in a shelf-stock package. Whether building a boosted street engine or an all-out race powerplant, these LS stroker pistons are engineered to handle the demands of severe-duty builds.
