Carrillo SC7601-4 Pro-H Straight H-Beam Connecting Rods

Built by CP-Carrillo — the industry benchmark for performance connecting rod technology — these rods are manufactured in the USA from Carrillo's proprietary Carrilloy 4330M chromoly steel alloy, a chrome/nickel/molybdenum/vanadium blend that meets all VAR (Vacuum Arc Re-Melt) ASTM standards and delivers a tensile strength of 195,000 PSI with a yield of 182,000 PSI.

Key Features:

• Straight H-beam design — the stoutest configuration available for handling extreme cylinder pressures and inertia loads
• Forged from oversized proprietary Carrilloy 4330M steel billets for correct grain flow and surface inclusion removal
• Fully CNC-machined with in-process probing to ensure dimensional integrity
• Magnaflux inspected twice during production to detect any surface flaws
• Rockwell hardness tested to validate heat treatment
• Final 200% shot-peen operation to relieve tensile stress and maximize fatigue life
• Laser-etched job number for full traceability
• Set-balanced to ±1 gram for smooth, precise reciprocating assembly
• Includes premium SPS/Carrillo rod bolts — available in WMC (H11 tool steel, 220,000 UTS) or CARR (MP35N, 285,000 UTS) configurations
• Rod bolts feature a patented asymmetrical thread design for improved clamp load and fastener fatigue life
• Made in the USA

CP-Carrillo Pro-H connecting rods are trusted by professional engine builders across drag racing, road racing, oval track, off-road, and powersports applications. The SC7601-4 delivers the reliability, strength, and precision quality control that serious performance builds demand.
