Carrillo SC7706-1 Pro-H Series Forged Steel Connecting Rod

The Carrillo SC7706-1 is a high-performance forged steel connecting rod engineered for demanding racing and high-horsepower engine builds. Manufactured by CP-Carrillo in Irvine, California, this rod is built to exacting standards using proprietary materials and precision CNC machining processes trusted by professional engine builders worldwide.

Key Features:

• Carrilloy Proprietary Steel: Manufactured from CP-Carrillo's exclusive 4330M chrome-nickel-moly-vanadium alloy, validated by both supplier and an independent metallurgist to confirm desired physical and chemical properties
• Oversized Forging Process: Each rod is produced from oversized forgings to ensure proper grain flow and elimination of surface inclusions for consistent strength and durability
• Shot Peening: A controlled shot peen operation relieves tensile stresses from grinding and introduces beneficial compressive stresses to maximize fatigue life
• Multi-Step Quality Inspection: Every rod is magnafluxed a minimum of twice and Rockwell hardness tested to validate heat treatment — then laser-serialized for full traceability
• Precision CNC Machined: All critical CNC operations are performed with in-process probing to validate dimensional integrity at every stage
• High-Performance Fasteners: Compatible with CP-Carrillo's WMC (H11 Tool Steel, 220 KSI UTS) or CARR (MP35N Multiphase, 285 KSI UTS) rod bolt systems
• Made in the USA: Designed and manufactured at CP-Carrillo's state-of-the-art facility in Irvine, California

The Carrillo SC7706-1 connecting rod is an ideal choice for performance engine rebuilds requiring superior strength, precise tolerances, and proven reliability under extreme RPM and cylinder pressure loads.
