The Racer's Choice Piston Series.

*Now Featuring ArmorPlating®*

Mentor, Ohio (March 11, 2013) - The best kept secret  for years, until now! In the past, Racer's Choice  parts were reserved for top race teams & top mechanics only. Now you can own the same race technology used by the pros. These high-tech, feature-rich piston designs offer maximum compression ratios, ArmorGlide® skirt coating, ultra stiff strutted & boxed forging designs, titanum nitride-coated rings and Wiseco's new ArmorPlating® coating. This all adds up to more power that can be sustained longer.

Racer's Choice Pistons are the ultimate piston choice and are packed with performance enhancements. These cutting edge designs produce the maximum power possible in each application and are designed to keep you at the front of the pack. Most Racer's Choice pistons are a two ring 4-stroke application. With one less ring, piston weight and friction are reduced, power is increased and throttle response is instantaneous! Our proprietary ArmorPlating® coating improves ring seal, eliminates micro-welding of the rings in the ring grooves and improves the pistons ability to defend against deteonation. Racer's Choice pistons offer additional performace to those racers and engine builders who want the most out of every race engine they build.

World renowned for our work building race winning pistons, Wiseco utilizes experience from a diverse background of the most sophisticated engines in such venues as Formula 1, Indy Racing League (IRL), NHRA Pro Stock, Moto GP, AMA Superbike, AMA Motocross and Supercross to design and manufacture the highest technology pistons available. Extensive engineering goes into each Wiseco Automotive part to provide the maximum torque and horsepower ever driver wants. We offer Custom Pistons and Rotating Assemblies for a broad range of applications from the most popular Domestic models to Sport Compact, and Drag only use applications.

Piston Engineering / ArmorGlide™ Coating

Wiseco’s detailed skirt shapes and profiles are very specific to each application. Variable cam programm ing software developed in house allows Wiseco to produce high-performance shapes unique to only Wiseco. The skirt shape (barrel/cam) is one of the most functional areas on the piston, and provides stability and smooth operation in the cylinder bore. Stability is important for proper ring seal, reduced friction, and quiet operation. Each skirt shape is designed for a specific running clearance, based on coefficient of thermal expansion of the piston alloy. Some forging alloys expand more than casting alloys, but each Wiseco piston is designed with the proper installed clearance to produce the most power, least wear, and best seal at running temperature, for each application. Comparing installed clearances on cast vs forged parts is not indicative of the running clearance at temperature. Wiseco engineers have a strong background in all forms of racing applications, and produce the best shapes and designs in the industry. 

Some of our forged pistons offer our new ArmorGlide™ skirt coating, which is the result of testing, development, and benchmarking through Wiseco’s rigorous in-house dyno program. The outcome is the ultimate in skirt coating toughness, lubrication, and bond technology working together to minimize friction, maximize horsepower, and provide improved wear resistance. Not only is ArmorGlide™ a high-tech lubricant that reduces friction, but it also allows the piston to be fitted tighter within the bore allowing a better ring seal and reduced noise from piston rock.

In 1940 Clyde Wiseman ventured into his garage on the East Side of Cleveland, Ohio and began producing pistons for himself and a few friends. Word of his high quality work spread quickly, and in 1941 Wiseco Piston was established to service the needs of motorsports enthusiasts.

Today, Wiseco’s corporate headquarters in Mentor, Ohio, boasts of over 150,000 square feet of state-of-the art forging and CNC machining equipment. Wiseco also has fully stocked, strategically located distribution centers within Canada and Europe to serve markets all over the world. 

With our coast to coast domestic distribution system and international customers in Europe, South America, Africa, Australia, and Asia, Wiseco is the world leader in the manufacturing of hi-performance, forged pistons for the snowmobile, motorcycle, ATV, personal watercraft, outboard marine and automotive markets.

Wiseco engineers utilize the latest in 3D design and finite element modeling software to ensure every Wiseco design is developed to provide the greatest strength and lightest weight for each application. Our in-house Dyno facility, equipped with the latest technology, along with our field-testing network, insure that our products meet the expectations of the demanding motorsports industry.
