Our pistons are manufactured from special materials like eutectic aluminum, ductile iron and steel alloy. Surface treatments such as anodizing and nitriding are typically used in the ring grooves and crown area for durability. Anti-friction coatings like tinning, phosphate and graphite provide scuff protection during initial engine break in. Our pistons are designed and manufactured to meet or exceed the most rigorous and stringent specifications.
