Wiseco is unique because we forge all of our own pistons in house, and produce all of our own forge tooling right here in the USA. This allows us to con- trol all aspects of our manufacturing process from raw bar to skirt coating finished parts. In addition, in-house dyno testing gives Wiseco the ability to develop state-of-the-art tech- nology such as new shapes, coatings, and components, and lead the industry through rig- orous R&D. Linking all segments of Wiseco’s organization through design, testing, man- ufacturing, and distribution allows us to fulfill market needs with minimum lead-times. Extreme racing conditions demand the strength and toughness that only forged pistons can of- fer. Compared to cast pistons, forgings are tougher and more durable, and will stand up to the abuse that high performance motorsport applications require. Most castings are brittle, have no grain structure and tend to fail catastrophically when the material yield strength is exceeded. Forgings have condensed grain that is aligned to the features of the part, which produces higher mechanical properties, and resistance to impact and fatigue. Each forging is designed to optimize the strength-to-weight ratio, and maximize performance. Piston Engineering / ArmorGlide Coating Wiseco’s detailed skirt shapes and profiles are very specific to each application. Variable cam programming 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. Top End Piston Kits Wiseco’s complete top end Piston Kits are offered for nearly every popular application in the powersports market. These kits contain everything you need to complete your rebuild the right way, the first time. High quality parts specifically chosen by us to match our forged pistons are included in this kit for easy one stop shopping. • 2-stroke kits feature our Pro-Lite™ pistons that are CNC machined for optimal cam shape and profile for peak HP and service life. • 4-stroke kits feature a ‘race-ready’ dome finish with smooth edges for improved combustion flow. Horizontal slot-pin oiling reduces friction and provides scuff resistance, along with a pressure seal groove for maximum ring seal. • Most PK/SK/WK/VT kits from Wiseco feature a complete top end gasket kit that gives you everything you need to complete your rebuild from premium materials. • 4-stroke race applications feature Wiseco’s ArmorGlide™ skirt coating to provide reduced friction and noise to contribute to increased horsepower. • Dedicated forgings used for superior strength to weight ratio utilizing aerospace alloy. • High Performance ring kit and alloy pin included with each piston kit for extended life and sustained power.
