Carrillo SCR5360-4 Pro-H Straight H-Beam Connecting Rods

Manufactured in the USA from Carrillo's proprietary Carrilloy (4330M chromoly steel) — a chrome, nickel, moly, vanadium alloy meeting all VAR (Vacuum Arc Re-Melt) ASTM standards — these rods deliver the strength, durability, and fatigue resistance demanded by serious performance builds.

Key Features:

• Straight H-Beam design — the stoutest beam configuration available for maximum load handling under extreme engine conditions
• 5.360" center-to-center rod length — application-specific forging with no excess reciprocating mass
• Proprietary Carrilloy steel forging — heat validated by both the supplier and an independent metallurgist to confirm physical and chemical properties
• Full-floating wrist pin design with bronze bushed small end
• WMC or CARR rod bolt options — WMC bolts feature H11 tool steel with 220,000 psi UTS; CARR bolts use MP35N material with 285,000 psi UTS and asymmetrical thread design for superior clamp load
• Mar-aged heat treat process — results in UTS of 195,000 psi and yield of 182,000 psi while maintaining low notch-sensitivity and ductility
• Magnafluxed twice during production and Rockwell hardness tested to validate heat treat integrity
• 200% shot-peen operation — relieves tensile stresses and induces beneficial compressive surface stresses for increased fatigue life
• CNC-machined with in-process probing — validates dimensional integrity at every critical stage
• Laser-etched job number for full traceability
• Made in the USA

Carrillo Pro-H connecting rods are the benchmark choice for engine builders competing in drag racing, road racing, oval track, and high-horsepower street performance builds. Each set comes with a detailed specification printout including individual rod specs and proper torque/stretch values for rod bolt installation.
