The Carrillo SC7470-6 is a high-performance forged steel connecting rod set designed for demanding race and high-performance engine applications. Built to Carrillo's exacting standards, these rods deliver the strength, precision, and reliability that professional engine builders trust.

Key Features:

• Proprietary Carrilloy Steel: Manufactured from Carrillo's exclusive 4330M chrome-nickel-moly-vanadium alloy, meeting all VAR (Vacuum Arc Re-Melt) ASTM standards for maximum consistency and material integrity
• Oversized Forgings: Each rod is machined from an oversized forging to ensure proper grain flow and guaranteed removal of any surface inclusions or conversions generated during the forging process
• Precision CNC Machining: All critical CNC machines are equipped with probing to accurately validate dimensional integrity throughout production
• Multi-Step Inspection: Every rod is magnafluxed at least twice and Rockwell tested to validate the heat treat procedure, ensuring consistent hardness and durability
• Shot Peened Finish: A final controlled shot peen operation relieves tensile stresses and introduces beneficial compressive stresses to increase fatigue life
• CARR Bolt Fasteners: Equipped with Carrillo's CARR Multiphase (MP35N) rod bolts featuring a UTS of 285,000 psi and asymmetrical threads for optimized clamp load and fatigue life — ideal for extreme RPM applications
• Laser-Etched Job Number: Each rod is laser-marked for full traceability and quality documentation
