Description

The JE Pistons 371964R is a set of flat-top pistons designed for Chevrolet LS engines with a 4.075-inch bore. These pistons are forged from a strong 4032 aluminum alloy, offering a blend of strength and affordability suitable for performance rebuilds and street/strip applications.

Featuring JE Pistons' proprietary Forged Side Relief (FSR) design, these pistons minimize friction and power loss. They also include a low-friction skirt coating to reduce wear and operating noise, while an accumulator groove helps improve ring seal for consistent power output.
