Wiseco 6466LX2 Forged Piston Chrysler 5.7L Hemi +4cc Dome 3.937in Bore Professional Series — image 1

Product Details

The Wiseco 6466LX2 is a Professional Series forged replacement piston engineered for the Chrysler 5.7L Gen III Hemi engine. Forged from 2618 aluminum alloy and manufactured at Wiseco's Mentor, Ohio facility, this shelf-stock piston is built to handle heavy-duty and severe-duty race applications where off-the-shelf OEM parts simply won't cut it.

This single piston features a +4cc dome profile designed to raise compression and optimize quench during the combustion cycle, helping resist detonation and pre-ignition. Precision-machined valve pockets allow maximum airflow around the valves, making this piston compatible with oversized valves and high-lift camshafts.

Key Specifications:

Bore: 3.937 in.
Compression Height: 1.205 in.
Stroke: 3.580 in.
Rod Length: 6.243 in.
Pin Diameter: 0.927 in.
Dome Volume: +4cc
Piston Material: 2618 Aluminum Alloy
Sold as: Single piston

Key Features:

ArmorGlide® Skirt Coating — Proprietary moly-based skirt coating reduces operating friction, minimizes cylinder wall wear, and allows the piston to be fitted tighter in the bore for improved ring seal and reduced piston rock
2618 Forged Aluminum Construction — Superior tensile strength and heat resistance compared to cast or hypereutectic pistons, engineered to handle extreme cylinder pressures and sustained high-RPM use
Precision Ring Grooves — Machined to exacting tolerances with proper orifice and accumulator volume, delivering excellent ring seal and minimized blow-by
Optimized Dome & Crown Shapes — Promotes efficient intake charge scavenging during valve overlap and resists detonation and pre-ignition under high-compression conditions
Valve Pocket Design — Allows maximum airflow around the valves and accommodates oversized valves and aggressive high-lift camshaft profiles
USA Manufactured — Engineered, forged, and CNC-machined at Wiseco's state-of-the-art Mentor, Ohio facility

The Wiseco 6466LX2 is a Professional Series shelf-stock piston, delivering custom-level performance and durability in a ready-to-ship format. Paired with a premium ring set and wrist pins, it is the ideal choice for serious engine builders pushing the Chrysler 5.7L Hemi platform to its limits.

I ordered an Optima battery for my truck after I did a Google search for the battery. Autoplicity was the cheapest on the Web. Even cheaper then eBay. They got me hooked. Thanks Autoplicity
