Carrillo SC7612-4 Sport Compact Connecting Rod Set

The Carrillo SC7612-4 is a high-performance steel connecting rod set engineered for demanding racing and performance engine applications. Built to CP-Carrillo's exacting standards, these rods are manufactured in the USA from proprietary oversized steel forgings to ensure proper grain flow and eliminate surface inclusions before any machining begins.

Key Features:

• Proprietary Carrilloy Steel: Manufactured from CP-Carrillo's 4330M chrome-nickel-moly-vanadium alloy steel, vacuum arc re-melted (VAR) to ASTM standards for maximum consistency and strength
• Forged H-Beam Design: Lightweight H-beam profile reduces reciprocating mass for improved engine response while delivering superior tensile and compressive strength
• Shot Peened Finish: Controlled shot peen operation relieves tensile stresses and introduces beneficial compressive stresses to significantly increase fatigue life
• Dual Quality Inspections: Each rod is magnafluxed twice during production and Rockwell hardness tested to verify heat treatment integrity
• Laser-Etched Job Number: Full traceability from raw material to finished part
• High-Strength Fastener System: Compatible with CP-Carrillo WMC (H11 tool steel, 220 ksi UTS) or CARR (MP35N, 285 ksi UTS) rod bolts featuring asymmetrical threads for optimized clamp load and fatigue life
• Made in the USA: Manufactured at CP-Carrillo's facility using advanced CNC machining centers with integrated probing for dimensional validation

CP-Carrillo connecting rods have earned a benchmark reputation across virtually every form of motorsport, from drag racing and oval track to road racing and off-road competition. The SC7612-4 set delivers the precision weight-matching, dimensional accuracy, and material integrity that professional engine builders demand.
