Carrillo SCR13679-1 Pro-H 3/8 WMC Bolt Connecting Rod Single - VW/Audi TTRS RS3 2.5L

The Carrillo SCR13679-1 is a single Pro-H (H-Beam) forged steel connecting rod designed for the Volkswagen and Audi 2.5L turbocharged five-cylinder engine platform. Featuring a 3/8 in. WMC (H11) rod bolt and a 144mm rod length with a 23mm wrist pin bore, this rod is engineered to withstand the extreme forces generated in high-output and race-built applications.

Key Features:

• Pro-H Straight H-Beam design — the strongest H-beam configuration in Carrillo's lineup, purpose-built for high-horsepower forced-induction builds
• 3/8 in. WMC (H11) rod bolts — rated to support demanding RPM levels in performance applications
• 144mm rod length with a 23mm small-end pin bore and 50.6mm big-end bore
• Proprietary "Carrilloy" steel forgings — a chrome, nickel, molybdenum, and vanadium alloy manufactured to meet VAR (Vacuum Arc Re-Melt) ASTM standards
• Oversized forging process — ensures correct grain flow and eliminates surface inclusions for maximum structural integrity
• USA manufactured — designed and produced at CP-Carrillo's facility in Irvine, California
• Single rod — sold individually; order quantity 5 for a complete set on the 5-cylinder engine

The SCR13679-1 is sold as a single connecting rod, making it ideal as a replacement or for building out a custom quantity set. As with all Carrillo rods, bolt installation using the manufacturer's recommended stretch method is preferred over torque-only tightening for optimal preload accuracy. Note: always verify connecting rod clearance within the engine block, as clearances in the 2.5 TFSI engine bay are tight.
