Carrillo SC7116-4 Pro-H Connecting Rod

CP-Carrillo has been recognized as a world leader in connecting rod manufacturing since 1963, supplying custom and prototype rods to virtually every major automotive and motorsports venue.

These rods are machined from Carrillo's proprietary Carrilloy steel — a chrome, nickel, moly, vanadium alloy that meets all VAR (vacuum arc re-melt) ASTM standards. The heat is validated by both the supplier and an independent metallurgist to confirm physical and chemical properties. All heat treat processes use a mar-aged operation resulting in a UTS of 195,000 psi with a yield of 182,000 psi, while maintaining low notch-sensitivity and ductility.

Key Features:

• Pro-H straight H-beam design for maximum rigidity and strength under extreme loads
• Manufactured from oversized proprietary Carrilloy steel forgings for proper grain flow and elimination of surface inclusions
• Each rod is magnafluxed at least twice and Rockwell tested to validate heat treat
• Final 200% shot-peen operation for superior fatigue resistance
• All critical CNC machines equipped with probing to validate dimensional integrity
• Compatible with Carrillo WMC (H11 tool steel, 220,000 UTS) or CARR (MP35N Multiphase, 285,000 UTS) rod bolts featuring a patented asymmetrical thread design

CP-Carrillo connecting rods are built to perform flawlessly in today's demanding racing and high-performance internal combustion engines. Each rod set ships with a detailed specification printout including proper torque and stretch values for the rod bolts.
