Built to handle the extreme demands of high-horsepower and high-RPM forced induction applications, these rods are a direct upgrade over factory connecting rods for performance builds.

Each rod is manufactured in the USA from Carrillo's proprietary Carrilloy steel — a chrome, nickel, molybdenum, and vanadium alloy that meets all VAR (vacuum arc re-melt) ASTM standards. Oversized forgings ensure proper grain flow and the elimination of surface inclusions, resulting in exceptional strength and fatigue resistance.
