Wiseco Professional Series forged piston set for Chevrolet LT1 engines, a set of eight pistons with a 4.065 in bore and 1.105 in compression height. Suited to heavy-to-severe duty racing, these pistons are forged from 2618 aluminum and feature fully machined crowns, precision ring grooves and an anti-detonation groove, with premium rings included. ArmorGlide skirt coating resists seizure and reduces friction; forced pin oiling and a 0.927 in pin diameter complete the spec.
