Speedmaster Oil Pans are designed from high-quality cast aluminum or steel to hold and cool oil. These oil pans have a hand polished, black painted or zinc plated finish for a dressed-up look and are designed to hold the amount of oil needed for engine lubrication while running, including a reserve. Speedmaster Oil Pan Gaskets are designed to meet the demands of today's performance engines that create extreme amounts of vacuum and pressure in the oil pan. These gaskets are made from a cellulose/nitrile material that provides excellent tensile strength and superior blowout resistance, with a latex coating that conforms to surface irregularities for a superior seal.
