The WISECO Piston Kit features a 95.00 mm piston with a 100% billet-machined construction designed for strength, optimized fit, and dyno-proven power gains. Its asymmetric skirt design promotes improved wear and even loading on the major thrust skirt, while the high-compression design supports increased torque and throttle response.
The kit includes rings, a piston pin, and circlips. The precision-fit ring package includes a custom-lapped compression ring for improved power, and the pressure seal groove helps reduce ring lifting and power loss. A DLC-coated piston pin reduces friction and improves scuff resistance, while enhanced pin oiling supports lubrication and reduced friction. The dome design promotes improved flame travel for more efficient air and fuel burn, and the ArmorGlide® skirt coating supports quieter operation and improved scuff resistance. This piston kit is made in the USA.
