Description

The JE Pistons piston set is a set of 8 asymmetrical FSR (Forged Side Relief) pistons. These pistons incorporate modern forging design with a larger skirt on the major thrust side and a smaller, friction-reducing skirt on the minor thrust side. Combined with precision CNC machining, the result is a high-strength, lightweight piston that is extremely durable. The bore size is 4.000 inches (101.6mm), and they are made from 2618 material.
