FORD 351WC ROD 5.956 FLAT TOP +2CC 1V KB HYPER PISTON SET

The United Engine & Machine Co KB110.060 is a set of eight hypereutectic pistons designed for high-performance applications. These pistons feature a flat-top design with a 4.060-inch bore and a 3.500-inch stroke, fitting SB Ford 351W engines and compatible with Cleveland cylinder heads.

Key features include CNC-machined pin bores for accuracy, an accumulator groove for improved ring seal, and diamond-finished skirts. The pistons are constructed from a 390 aluminum alloy with 16 percent silicon, allowing for tighter piston-to-wall clearance. Wrist pins and spiral lock rings are included, but piston rings are sold separately.
