The Manley Platinum Series 37cc Dish Extreme Duty piston set for BMW N55/S55 engines provides a heavy-duty forged piston option for high-stress applications where added durability is required. It carries the same design intent as the Platinum line but targets more demanding duty cycles. Built from domestic 2618 alloy forgings with cam-and-barrel skirt profiles, tool steel wrist pins, and precision ring lands and grooves, these pistons balance power potential with careful skirt-to-ring machining for reliable sealing.
