Description

The United Engine & Machine Co 9902HC.STD is a set of pistons designed for performance and street applications. These pistons are constructed from a hypereutectic 390 alloy with 16% silicone, offering durability and good thermal properties.

They feature flat tops with -5cc, two symmetrical valve reliefs, and a compression height of 1.565 inches. The pistons have CNC-machined pin bores for accuracy, an accumulator groove for improved ring seal, cast-in oil returns, and diamond-finished skirts with Molykote coating. Wrist pins and spiral locks are included, but rings are sold separately (5/64 x 5/64 x 3/16).
