Carrillo SC7115X-4 Sport Compact Connecting Rod

The Carrillo SC7115X-4 is a high-performance forged steel connecting rod set designed for sport compact engine applications.

Key Features:

• Manufactured from CP-Carrillo's proprietary Carrilloy (4330M) forged steel alloy for exceptional strength and durability
• Equipped with CARR (MP35N) bolt upgrade — denoted by the "X" suffix — featuring an ultimate tensile strength (UTS) of 285,000 PSI and rated for indefinite re-torque cycles when the stretch method is followed
• Each rod is magnaflux tested twice and Rockwell hardness tested to validate the heat treatment process
• Finished with a controlled 200% shot-peen operation to replace tensile surface stresses with beneficial compressive stresses, maximizing fatigue life
• Manufactured from oversized forgings to ensure proper grain flow and elimination of any surface inclusions
• All critical CNC machining is performed with in-process probing to validate dimensional integrity
• Each rod is laser-etched with a job number for full traceability
• Includes assembly lubricant and build sheet with torque/stretch specifications

CP-Carrillo connecting rods are trusted by professional and amateur racers worldwide across drag racing, road racing, endurance, and sport compact applications. The SC7115X-4 delivers the strength, precision, and reliability required for high-horsepower builds where stock rods are inadequate.
