Digital Diamond Profile (DDP) Technology is a digital actuated diamond turning process that produce precision skirt profiles. The barrel profile of the DDP piston promotes an oil wedge between the skirt and cylinder wall.
DDP pistons also feature Thermal Arching Compensation (TAC) ring groove geometry. Ring grooves machined with an uptilt to offset thermal "arching" distortion. Uptilt squares the ring face to the cylinder for increased power and decreased oil consumption.
Speed Pro's next generation Duroshield skirt coating is also added to reduce friction across entire RPM range. Increased wear resistance for long life and superior NVH (noise, vibration, and harshness) reduction.
Precision machined pin bores allow fixed or floating wrist pin installation. Piston/pin assemblies are weight matched to 4 gram (+/- 2 gram) maximum variation within every engine set.

WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
WARNING: The wires of these products contain chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Wash hands after handling.
