Carrillo SC7474-6 Pro-H Steel Connecting Rod

The Carrillo SC7474-6 is a Pro-H beam connecting rod built from Carrillo's proprietary Carrilloy steel — a chrome, nickel, moly, vanadium alloy manufactured to VAR (Vacuum Arc Re-Melt) ASTM standards. Carrillo has been the benchmark for high-performance connecting rod manufacturing since 1963, supplying rods to professional racing programs across automotive, motorcycle, and powersports disciplines worldwide.

The Pro-H beam configuration is Carrillo's strongest beam design, engineered to handle the most extreme cylinder pressures, high-RPM loads, and forced induction applications where OEM rods simply cannot survive.

Key Features:

• Carrilloy proprietary steel — chrome, nickel, moly, vanadium alloy meeting all VAR (vacuum arc re-melt) ASTM standards for superior grain structure and material consistency
• Mar-aged heat treatment — results in an ultimate tensile strength (UTS) of 195,000 psi and a yield of 182,000 psi, while preserving low notch-sensitivity and ductility
• Pro-H beam architecture — Carrillo's stoutest beam design, optimized for maximum strength under extreme cylinder pressure and high cyclic loads
• Oversized forging process — ensures proper grain flow and removes potential surface inclusions before precision CNC machining begins
• CNC dimensional probing — all critical machining operations are validated with in-process probing for dimensional integrity
• Dual magnaflux inspection — each rod is magnaflux inspected a minimum of twice during production to detect any subsurface defects
• Rockwell hardness tested — every rod is Rockwell tested to verify heat treatment conformance
• Shot-peen finish — final shot-peen operation enhances fatigue life and surface durability
• Sold individually — verify the quantity required for your specific build

Carrillo connecting rods are a trusted foundation in high-horsepower, boosted, and competition builds. Each rod ships with a detailed specification printout including proper bolt torque and stretch values for professional installation.
