Carrillo SCR5142-4 Pro-Series Connecting Rods

Manufactured by CP-Carrillo in the USA, these rods are built to exacting standards using the company's proprietary Carrilloy steel — a chrome, nickel, moly, vanadium alloy that meets all VAR (vacuum arc re-melt) ASTM standards for superior strength and fatigue resistance.

Key Features:

• Manufactured from Carrillo's proprietary Carrilloy 4330m alloy steel for maximum tensile strength and durability
• Precision CNC-machined from oversized forgings to ensure proper grain flow and eliminate surface inclusions
• Each rod is magnafluxed twice and Rockwell hardness tested during production for quality validation
• Shot-peen finished to relieve surface tensile stresses and increase fatigue life
• Compatible with CP-Carrillo WMC (H11 tool steel) or CARR (MP35N multiphase) rod bolts
• Laser-etched job number on each rod for full traceability
• Made in the USA at CP-Carrillo's Southern California facility

CP-Carrillo connecting rods are trusted by professional racing teams across drag racing, road racing, and off-road motorsports. The SCR5142-4 set is built to withstand extreme cylinder pressures and high RPM operation, making it an ideal upgrade for performance street builds and forced induction applications alike.
