Carrillo SC7114-4 Pro-H H-Beam Connecting Rod Set with CARR Bolts

Built by CP-Carrillo — one of the most trusted names in performance connecting rod manufacturing — these rods are machined from Carrillo's proprietary Carrilloy (4330M chromoly steel), a chrome, nickel, moly, vanadium alloy that meets all VAR (vacuum arc re-melt) ASTM standards for maximum strength and fatigue resistance.

The "SC" prefix in the part number designates these rods are equipped with CARR (MP35N Multiphase) rod bolts, the premium fastener option in the Carrillo lineup. CARR bolts feature an ultimate tensile strength (UTS) of 285,000 PSI and are rated for an unlimited number of torque cycles (provided the bolt-stretch method is followed and bolts are never over-yielded), making them the preferred choice for high-revving and frequently disassembled race engines.

Key Features:

• Machined from proprietary Carrilloy 4330M chromoly steel — a chrome, nickel, moly, vanadium VAR alloy
• CARR (MP35N Multiphase) rod bolts included — 285 KSI UTS, rated for unlimited torque cycles
• CARR bolt asymmetrical threads provide evenly distributed thread engagement for increased clamp load and improved fastener fatigue life
• Each rod ships with a specification card listing critical dimensions, weight, job number, and bolt installation data
• Includes Carrillo assembly lubricant — required for proper bolt installation and clamp load
• Manufactured in the USA using advanced forging and CNC machining processes
• Compatible with Carrillo's recon service for inspection, magnaflux, re-honing, and re-bushing

CP-Carrillo recommends installing rod bolts using the bolt-stretch method rather than torque alone to ensure accurate preload. Every rod leaves the facility with a spec card documenting critical dimensions and bolt installation specifications. These connecting rods are proudly made in the USA and backed by CP-Carrillo's decades of proven motorsports performance.
