Carrillo SCR8554-1 Pro-H 3/8 WMC Connecting Rod Single 144mm Audi TFSI

Carrillo SCR8554-1 is a single Pro-H beam forged connecting rod designed for high-performance and racing applications. Featuring a 144mm (5.669") center-to-center length, a 0.866" (22mm) pin size, and a 3/8" WMC rod bolt, this rod is engineered to withstand extreme cylinder pressures and elevated RPM demands. The "-1" suffix denotes this is sold as a single rod, ideal for replacing an individual unit or building custom configurations.

Key Features:

• CNC-machined on probing-equipped machines for precise dimensional integrity
• Sold as a single rod (1 piece)

Carrillo connecting rods are manufactured from an oversized forging to ensure proper grain flow and eliminate surface inclusions. Each rod undergoes a mar-aged heat treatment process resulting in a UTS of 195,000 psi with a yield of 182,000 psi, while maintaining low notch-sensitivity and ductility. These are special-order items and are not eligible for cancellation or return.
