Carrillo SCR5142-1 Pro-H Connecting Rod

The Carrillo SCR5142-1 is a high-performance forged connecting rod engineered for demanding powersports and performance engine applications. Built by CP-Carrillo — an industry leader in precision connecting rod manufacturing since 1963 — this rod is crafted from the brand's proprietary Carrilloy steel, a chrome-nickel-moly-vanadium alloy produced to tightened VAR (Vacuum Arc Re-Melt) ASTM standards for superior strength and consistency.

Key Features:

• Forged from proprietary Carrilloy 4330m chromoly steel for exceptional tensile strength and fatigue resistance
• Fully CNC-machined from oversized forgings to ensure proper grain flow and eliminate surface inclusions
• 100% magnaflux inspected twice during production to detect any surface flaws before final machining
• Rockwell hardness tested to validate the heat treatment process on every individual rod
• Shot-peened finish to relieve tensile stress and maximize fatigue life under high-RPM, high-load conditions
• Each rod laser-etched with a job number for full traceability
• Manufactured in Irvine, California, USA

CP-Carrillo's rigorous multi-step quality control process — including probing on all critical CNC machines, dual magnaflux inspection, and a controlled shot peen operation — ensures every SCR5142-1 rod meets the uncompromising standards demanded by performance builders and racers worldwide.
