Carrillo SC7011-4 Pro-H Straight H-Beam Connecting Rods

Manufactured in the USA, these rods represent Carrillo's commitment to uncompromising quality, making them a trusted choice among professional engine builders worldwide.

Key Features:

• Proprietary Carrilloy Steel: Forged from Carrillo's exclusive 4330M chromium/nickel/molybdenum/vanadium alloy, meeting all VAR (vacuum arc re-melt) ASTM standards for maximum strength and fatigue resistance
• Straight H-Beam Design: The Pro-H configuration delivers the stoutest, most rigid beam geometry available, built to withstand the most abusive forces in race engine applications
• Oversized Forging Process: Each rod is machined from an oversized forging to ensure proper grain flow and eliminate surface inclusions generated during the forging process
• Advanced Heat Treatment: Mar-aged heat treat operation results in an ultimate tensile strength (UTS) of 195,000 psi and yield of 182,000 psi while maintaining low notch-sensitivity and ductility
• Shot Peened Finish: A final controlled shot peen operation relieves tensile stresses and introduces beneficial compressive stresses to maximize fatigue life
• Rigorous Quality Control: Each rod is magnafluxed at least twice and Rockwell hardness tested to validate the heat treat procedure; all critical CNC machines are equipped with dimensional probing
• High-Strength Rod Bolts: Equipped with Carrillo's proprietary fasteners featuring a patented asymmetrical thread design for evenly distributed thread engagement, improved clamp load, and superior fatigue life
• Full Traceability: Each rod receives a laser-etched job number for complete manufacturing traceability

Carrillo Pro-H connecting rods are produced in small batches with obsessive attention to detail, combining quality materials, precision forging, and high-tech design to deliver flawless performance. Each rod in the set is weight-matched for optimal balance in your build.
