Wiseco Professional Series forged piston set for Chevrolet LS engines, a set of eight pistons with a 4.165 in bore and 1.165 in compression height. Engineered for heavy-to-severe duty race use, these pistons are forged from 2618 aluminum with fully machined crowns, precision ring grooves and an anti-detonation groove, supplied with premium rings. ArmorGlide skirt coating lowers friction and resists seizure; forced pin oiling and a 0.927 in pin diameter complete the package.
