About this part

Product Details

This set includes eight forged pistons, designed for Chevrolet small block engines. Each piston is crafted from domestic 2618 alloy, a material chosen for its exceptional strength and ability to handle high performance demands. They feature a bore size of 4.065 inches, a compression height of 1.550 inches, and a -4.00cc valve relief, which is crucial for proper valve clearance in performance builds.

Manley has incorporated proven cam and barrel skirt profiles into these pistons. This design helps generate significant power while also being gentle on your cylinder walls, contributing to longer engine life. The ring lands and grooves are machined to exacting standards, which is key for achieving a better ring seal. This improved seal means more efficient combustion and ultimately, more power from your engine. The pistons also come standard with premium chrome moly wrist pins, and Manley's unique fixturing process ensures ultimate squareness between the ring groove and the skirt, a detail that matters for consistent performance.

These pistons are a popular choice among professional engine builders and tuners who need reliable components for high-output engines. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to manufacturer installation instructions for proper fitment and assembly procedures.
