Please note that this is the original piston style with a single nickel insert on the top ring land and has a 4 ring design. If you currently have the tri-tech piston 3095747, this piston is no longer available. In order to use this piston with your engine you would need to replace in complete sets.
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. HDP pistons are designed and manufactured to meet or exceed the most rigorous and stringent specifications.
