Carrillo SC7708-1 Pro-Series Forged Connecting Rod Small Block Chevy

The Carrillo SC7708-1 is a high-performance forged connecting rod engineered for demanding small block Chevy applications. CP-Carrillo has been manufacturing industry-leading connecting rods since 1963, trusted by professional engine builders and racers worldwide for maximum strength and reliability.

Each Carrillo connecting rod is machined from Carrilloy — a proprietary 4330M chromoly steel alloy composed of chrome, nickel, molybdenum, and vanadium that meets all VAR (vacuum arc re-melt) ASTM standards. This proprietary material is forged oversized to ensure proper grain flow and eliminate surface inclusions before final machining.

Key Features:

• Forged from proprietary Carrilloy 4330M chromoly steel for superior strength-to-weight ratio
• CNC-machined with probing to validate dimensional integrity throughout production
• Magnaflux inspected twice during manufacturing to identify any surface flaws
• Rockwell hardness tested to validate heat treat procedure on every rod
• Shot-peened finish to relieve tensile stresses and extend fatigue life
• Laser-etched job number for full production traceability
• Sold individually — sold as a matched set when ordering a complete engine quantity

CP-Carrillo rods are manufactured in Irvine, California in a state-of-the-art facility using cutting-edge CNC technology and multi-step quality inspections. Each fastener is torqued to a specified stretch value — 80% of yield load — ensuring consistent and reliable preload in high-RPM racing environments.
