Construction & Design

Wiseco’s Professional Series pistons are forged using state-of-the-art processes that create a dense, uniform grain structure, maximizing strength and durability. The +4cc dome shape increases combustion chamber volume, allowing for higher compression ratios without compromising reliability. This design improves combustion efficiency and power potential, making it ideal for performance builds.

The 1.205-inch compression height is optimized to maintain factory piston-to-deck clearance, ensuring compatibility with stock cylinder heads and minimizing the need for additional machining. The pistons also feature a robust 0.927-inch pin bore to accommodate heavy-duty wrist pins, reducing wear and enhancing stability under high RPM and load conditions.

Installation & Fitment

This piston kit is a direct replacement for the Chrysler 5.7L 3rd Gen HEMI engine, matching the factory bore size of 3.917 inches. The pistons fit standard piston shelves and maintain OEM compression height specifications, allowing for straightforward installation by experienced engine builders. Typically, no modifications to the block or cylinder head are required when the engine is prepared to factory specifications.

The included premium piston rings simplify assembly and help ensure proper sealing from the start, reducing break-in time and enhancing engine longevity.
