Carrillo CR5373-1 High-Performance Forged Connecting Rod

The Carrillo CR5373-1 is a high-performance forged connecting rod engineered for demanding motorsports and performance engine applications. CP-Carrillo has been the benchmark in connecting rod technology since 1963, and this rod upholds that legacy with precision manufacturing and race-proven durability.

Each CR5373-1 connecting rod is machined from CP-Carrillo's proprietary Carrilloy steel — a chrome, nickel, moly, vanadium alloy that meets all VAR (Vacuum Arc Re-Melt) ASTM standards. Rods are produced from oversized forgings to ensure proper grain flow and to eliminate any surface inclusions generated during the forging process.

Key Features:

• Manufactured from proprietary Carrilloy forged steel alloy for superior strength and fatigue resistance
• Produced in the USA at CP-Carrillo's state-of-the-art manufacturing facility in Irvine, California
• Each rod is magnafluxed at least twice during production to detect surface flaws
• Rockwell hardness tested to validate heat treatment on every individual rod
• Shot-peened finish replaces tensile surface stresses with beneficial compressive stresses, extending fatigue life
• Laser-etched job number on each rod for full manufacturing traceability
• CNC-machined with in-process probing to ensure precise dimensional integrity

CP-Carrillo connecting rods are trusted by professional engine builders across drag racing, oval track, road racing, off-road, and powersports applications. The CR5373-1 is sold individually and is compatible with CP-Carrillo's recommended fastener installation procedure using the stretch method for optimal preload accuracy.
