Carrillo FE-328>-65394H-1 Pro-H Straight H-Beam Connecting Rod Single

The Carrillo FE-328>-65394H-1 is a single Pro-H straight H-beam connecting rod from CP-Carrillo, engineered for high-performance and motorsport applications. Built to withstand extreme engine loads, this rod is part of Carrillo's renowned Pro-H line — widely recognized as among the strongest H-beam connecting rod designs available for performance and racing engines.

Each rod is precision-forged in the USA from CP-Carrillo's proprietary Carrilloy steel — a chrome, nickel, moly, vanadium alloy (4330m) that meets all VAR (vacuum arc re-melt) ASTM standards. The oversized forging process ensures correct grain flow throughout the rod and eliminates surface inclusions for maximum fatigue resistance and consistent strength.
