Description

The JE Pistons 324018 features a new GM LS Inverted dome Asymmetrical FSR forging design that allows for popular stroke and rod combinations while eliminating reluctor wheel clearance problems. This design maintains a larger skirt on the heavily stressed major thrust side, while reducing friction with a smaller skirt on the minor thrust side. The result is a high strength, lightweight piston that significantly reduces friction in your engine. These pistons are machined for 1.2mm, 1.5mm, 3.0mm rings.
