• Wiseco forged pistons are superior in strength and design
• Engineered to provide the best possible path for combustion chamber heat transfer to cylinder walls
• Elliptically designed to provide a more uniform bearing surface under piston heat expansion, eliminating localized pressure and distribution thrust loads more evenly, thereby preventing piston collapse 
• Precision matched and balanced kits available for most machines; kits include forged pistons, rings, wrist pins, circlips and a top end gasket set

Our pistons, rings and kits are sold by application and bore size. Please note that STANDARD and OVERSIZES are not indicated. To get the correct part, you must know the standard bore size to make sure you are ordering either the standard or correct amount of oversize that you need. If you have any questions, please call Technical Service.
