Carrillo Nissan/Infiniti/Datsun VQ37HR Pro-SA 3/8 WMC Bolt Connecting Rods

These Carrillo Pro-SA connecting rods are specifically made for the 2008-2013 Infiniti G37 and the 2009-2014 Nissan 370Z, featuring the VQ37HR engine. If you're building a high-performance VQ37HR, strong connecting rods are essential for handling the increased stress and power. Carrillo has a solid reputation for making well-built internal engine components, and these rods are designed to be a significant upgrade over stock for demanding builds.

The Pro-SA series rods are forged from a proprietary steel alloy, which gives them a strong and durable structure capable of withstanding higher cylinder pressures and RPMs. They come equipped with Carrillo's 3/8 inch WMC bolts, known for their reliability and strength in performance applications. This combination of forged alloy and robust hardware means these rods can handle the rigors of boosted engines or aggressive naturally aspirated builds. The design ensures they fit right into the VQ37HR engine, making them a direct replacement for the factory rods when you're ready to step up the performance level.

When installing these rods, it's important to ensure proper balancing of the rotating assembly. This is a critical step for any engine rebuild, especially when using performance components like these. Always refer to the manufacturer's detailed installation instructions and torque specifications to ensure a successful build. These rods are a key component for anyone serious about extracting more power and reliability from their VQ37HR engine.
