• Specifically designed for the Chrysler 5.7L 3rd Gen HEMI for perfect compatibility and fitment

Construction & Design

These pistons are crafted using a no-expense-spared forging process that enhances grain structure and mechanical properties. The forged aluminum alloy construction offers excellent resistance to thermal expansion and mechanical stress, critical for race and high-performance engines. This ensures the pistons maintain integrity under the most demanding conditions.

The +4cc dome shape is optimized to increase compression without compromising piston-to-valve clearance, supporting improved combustion and power output. The shelf stock design maintains the factory piston deck height, simplifying installation and preserving engine geometry for consistent performance.

Installation & Fitment

This piston set is a direct replacement for the Chrysler 5.7L 3rd Gen HEMI engine, designed to fit a 3.937-inch bore and utilize a 0.927-inch wrist pin diameter. Installation requires no special machining or custom modifications beyond standard engine rebuild procedures. The pistons are compatible with existing connecting rods and piston pins designed for the 5.7L HEMI, ensuring a straightforward and reliable assembly process.
