Carrillo SC7543-1 Performance Connecting Rod Single

The Carrillo SC7543-1 is a high-performance connecting rod engineered and manufactured by CP-Carrillo, one of the most trusted names in precision engine components for motorsports and performance applications. Sold as a single connecting rod, it is designed to deliver exceptional strength, reliability, and consistency in demanding high-performance engine builds.

Key Features:

• Proprietary Carrilloy Steel: Manufactured from CP-Carrillo's proprietary 4330M chromoly steel alloy — a chrome, nickel, moly, vanadium blend meeting all VAR (vacuum arc re-melt) ASTM standards for maximum material integrity
• Forged from Oversized Blanks: Each rod is forged from an oversized billet to ensure proper grain flow and full removal of surface inclusions that can lead to premature fatigue failure
• 100% Magnaflux Inspected: After heat treatment, every rod is magnaflux inspected and Rockwell hardness tested before being machined to final dimensions
• Shot Peened Finish: A controlled shot peen operation relieves tensile surface stresses and replaces them with beneficial compressive stresses, significantly increasing fatigue life
• Precision CNC Machined: All critical dimensions are validated with probing on CNC machines to ensure dimensional accuracy and consistent fitment
• Laser Serialized: Each rod receives a laser-etched job number for full traceability and quality assurance
• Made in the USA: Designed and manufactured at CP-Carrillo's facility in Irvine, California

CP-Carrillo connecting rods are the choice of professional engine builders across drag racing, road racing, oval track, off-road, and powersports disciplines. The SC7543-1 is sold individually, making it a convenient option for targeted replacements or custom builds requiring precise per-cylinder specification matching.
