CP-Carrillo connecting rods are manufactured in the USA from proprietary Carrilloy 4330M steel — a chrome, nickel, moly, vanadium alloy that meets VAR (vacuum arc re-melt) ASTM standards — delivering exceptional tensile strength, fatigue resistance, and dimensional consistency.

Key Features:

• Proprietary Carrilloy 4330M steel forging for maximum strength-to-weight ratio
• H-beam cross-section design for superior rigidity under high loads
• Manufactured from oversized forgings to ensure proper grain flow and eliminate surface inclusions
• Compatible with WMC (H11 Tool Steel) or upgraded CARR (MP35N) rod bolt options
• Every rod ships with a detailed specification printout including per-rod specs and rod bolt torque/stretch values
• Made in the USA with full material and dimensional traceability

CP-Carrillo connecting rods are a benchmark choice for engine builders in drag racing, road racing, oval track, and high-performance street builds. The SC7617-4 set delivers the precision tolerances, weight balance, and material integrity required for demanding, high-RPM applications.
