Carrillo SCR5314-4 Pro-A Beam Forged Steel Connecting Rods

Part of Carrillo's proven SCR (Super-A beam) series, these rods are precision-manufactured in the USA to deliver exceptional strength, durability, and consistency under extreme engine loads.

Key Features:

• Proprietary Carrilloy Steel: Manufactured from CP-Carrillo's exclusive 4330M chrome, nickel, moly, vanadium alloy (Carrilloy), meeting all VAR (vacuum arc re-melt) ASTM standards for maximum material integrity
• Oversized Forging Process: Each rod is forged from oversized blanks to ensure proper grain flow and eliminate surface inclusions for consistent strength
• Rigorous Quality Control: Every rod is magnafluxed at least twice and Rockwell hardness tested to validate the heat treatment process
• Shot Peened Finish: A final controlled shot peen operation relieves surface tensile stresses and increases fatigue life
• CNC-Precision Machined: All critical CNC machines are equipped with probing to validate dimensional integrity throughout production
• High-Strength Fastener System: Compatible with CP-Carrillo's WMC (H11 tool steel, 220,000 UTS) or CARR (Multiphase MP35N, 285,000 UTS) rod bolt systems
• Laser-Etched Traceability: Each rod receives a laser-etched job number for full manufacturing traceability

CP-Carrillo connecting rods are trusted by professional engine builders across drag racing, road racing, and high-performance street applications. The SCR5314-4 delivers the precision fitment and proven reliability that Carrillo has built its reputation on for nearly 50 years.
