Wiseco K0415X05 Chrysler 6.4L Gen3 Hemi Professional Series Forged Piston Set 4.095 In. Bore

The Wiseco K0415X05 is a Professional Series forged piston set engineered specifically for the Chrysler 6.4L (392 cubic inch) Gen 3 HEMI engine. With a 4.095 in. bore diameter, these pistons are precision-manufactured for high-performance street, strip, and forced induction builds that demand more than factory components can deliver.

Key Features:

• 2618 High-Strength Forged Aluminum — dense, uniform grain structure for maximum tensile strength and fatigue resistance under extreme cylinder pressures
• ArmorGlide® Skirt Coating — proprietary coating provides seizure resistance, reduces piston-to-wall friction, and promotes quieter operation
• Fully Machined Crown Features — precision-machined dome geometry optimized for the Gen 3 HEMI combustion chamber
• Precision Ring Grooves — anti-detonation ring grooves machined to tight tolerances for consistent ring seal and long service life
• 4.095 in. Bore — fits standard 6.4L Gen3 HEMI bore with light overbore; ideal for rebuilds and performance engine assemblies
• Professional Series — Wiseco's top-tier piston line, designed for heavy to severe duty race builds with no-compromise construction
• USA Manufactured — engineered, forged, and machined at Wiseco's Mentor, Ohio facility

Wiseco Professional Series pistons include premium rings, wrist pins, and clips for a complete piston assembly. These forged pistons are the choice of serious engine builders looking for proven strength, precision fitment, and long-term durability in high-output Gen 3 HEMI applications.
