Here’s Wiseco’s 2618-alloy forged LS piston. The 2618 alloy is stronger than 4032, but typically wears quicker. To remedy this, Wiseco uses a permanent skirt coating that lasts the life of the piston. Forged pistons have a reputation for being noisy, so Wiseco offsets the pins like the OE to reduce noise on startup. The low-friction ring package is designed to maximize ring land thickness and utilizes a special oil ring design to reduce consumption.
