Product Overview

 JE Pistons - 311957 - JE Automotive - Chevrolet - Piston and Ring Kits


The JE Pistons new Asymmetrical FSR (Forged Side Relief) GM LS Flat Top forging piston design allows for the use of the most popular stroke and rod combinations while eliminating reluctor wheel clearance problems. The JE Pistons Asymmetrical forging design maintains a larger skirt on the heavily stressed major trust side, while reducing friction with a smaller skirt on the minor trust side. The result is a high strength, lightweight piston that significantly reduces friction in your engine. Lightweight and extremely durable, these JE pistons are machined for 1.2mm, 1.5mm, and 3.0mm rings.
