Description

JE Pistons 312112 GM LS3 Asymmetrical FSR Dome 4.080 Bore pistons feature a forged side relief design, accommodating popular stroke and rod combinations while eliminating reluctor wheel clearance issues. The asymmetrical forging maintains a larger skirt on the major thrust side for strength and reduces friction with a smaller skirt on the minor thrust side. These lightweight and durable pistons are machined for 1.2mm, 1.5mm, 3.0mm rings and include accumulator grooves, double pin oilers, and offset wrist pin.
