Description

JE Pistons' new GM LS Inverted dome Asymmetrical FSR (Forged Side Relief) forging design accommodates popular stroke and rod combinations while preventing reluctor wheel clearance issues. Its asymmetrical design maintains a larger skirt on the heavily stressed major thrust side and a smaller skirt on the minor thrust side to reduce friction. This results in a high-strength, lightweight piston that significantly reduces engine friction.
