FACT: The two skirts of a piston do not experience the same amount of mechanical loading. During the firing cycle, the load exerted on one piston skirt, referred to as the "major thrust side," can be up to 10 times higher than the load experienced by the opposing skirt, referred to as the "minor thrust side." The disparity in skirt loading can vary in magnitude depending on key variables including the engine's stroke, rod length, and peak cylinder pressure.

JE's asymmetrical pistons are the only aftermarket pistons designed to specifically handle the dissimilar mechanical loads experienced by both piston skirts. The resulting piston design features a large skirt area on the heavily loaded "major thrust side" and a small skirt area on the less loaded "minor thrust side". Overall, the piston design is stronger, yet lighter than previous designs.

All JE asymmetrical pistons utilize an offset wrist pin toward the major thrust side. By moving the pin toward the larger skirt, the balance of the piston on the wrist pin axis is nearly perfect. The offset, balanced piston reduces noise, increases piston stability, and helps ring seal.
