Description

The KB Performance Pistons SKB143L.STD is a hypereutectic aluminum piston designed for a 3.736 in. bore. It features a flat top with two valve reliefs and a stock stroke type. This piston is sold individually and is for the left side only.

The piston utilizes a lightweight, rigid-rib skirt design for stability in the bore. It offers improved oil control, reduced blow-by, increased ring life, and eliminates cold start-up knocking. The KB Performance pistons are made from 390 aluminum alloy and heat-treated to T6 standards, making them 30 percent stronger than ordinary untreated hypereutectics.
