Carrillo Nissan/Infiniti/Datsun VQ35HR Pro-H 3/8 WMC Bolt Connecting Rods

These Carrillo Pro-H connecting rods are built with 3/8" WMC bolts, a strong choice for the VQ35HR engine found in your 2007-2009 Nissan 350Z or 2007-2008 Infiniti G35. When you're pushing your engine hard, especially if you're looking at significant power upgrades, the stock connecting rods can become a weak point. Carrillo rods are a popular upgrade because they offer a solid foundation for a high-performance engine build, handling increased cylinder pressures and rotational forces much better than factory parts.

Carrillo uses a proprietary heat-treating process on their high-strength steel forgings, which helps create a rod that's both incredibly strong and durable. The Pro-H design is a well-known configuration in performance circles, offering a good balance of strength and weight. The 3/8" WMC bolts are a key component here, providing a secure and robust connection that's essential for keeping your engine running smoothly under stress. These rods are designed to fit right into your VQ35HR engine, making them a direct replacement for the stock rods, though professional installation is always recommended for critical engine components like these.

When building or rebuilding a performance VQ35HR engine, choosing reliable internal components is crucial. These Carrillo connecting rods are a well-built option that many builders trust for their strength and consistency. Make sure to consult your engine builder or a qualified mechanic about the specific requirements for your build, as other supporting modifications might be necessary to take full advantage of these upgraded rods.
