Description

The JE Pistons K452X165 is a set of 8 flat-top pistons designed for Chevrolet Small Block engines. These high-performance pistons feature a 4.165-inch bore, a 1.125-inch compression distance, and a 0.927-inch pin diameter. Crafted from durable 2618 forged aluminum, they are engineered to withstand extreme conditions in racing and high-performance applications. The set includes piston pins (part number 927-2750-15-51S), retainer locks (part number 927-042-CS), and oil rail supports (part number 4155-183), though the corresponding ring set (J10008-4165-5) is sold separately. These pistons are ideal for builders looking for robust and reliable components for their small block Chevrolet engine builds.
