Forged Piston Set, 86.00mm Bore

The Wiseco K573M86AP piston set is engineered for high-performance automotive builds, drawing on over 80 years of Wiseco's racing passion. These pistons are crafted in the U.S. from a 2618 aerospace alloy, ensuring superior tensile strength and a favorable strength-to-weight ratio crucial for demanding engine applications. Key features include a standard oversize, an 86.00 mm bore size, and a 30.00 mm compression height. The pistons incorporate an ArmorGlide skirt coating, which provides seizure resistance, reduces friction, and contributes to quieter operation. The fully machined crown and precision ring grooves further enhance performance and reliability. Additionally, these pistons feature a strutted forging for improved overall strength, making them suitable for heavy horsepower applications. The set includes the S734/22mm pin and the 8600XX ringset. With a dome volume of +8cc and a calculated compression ratio of 11.62:1, these pistons are designed to optimize performance. The specified dimensions include a connecting rod length of 5.472"/139 mm, a block height of 8.347"/212 mm, and a deck clearance of 0.001"-0.025". The gasket thickness is noted at 0.025"/0.63 mm, with a head volume of 50.5 cc.
