Carrillo Porsche 996 3.4L Pro-H 3/8 CARR Bolt Connecting Rods

If you're rebuilding the engine in your 1997-2012 Porsche Boxster, especially for a high-performance build targeting the 3.4L displacement, you need connecting rods that can handle the increased stress. These Carrillo Pro-H connecting rods are designed specifically for that purpose, offering a strong and reliable foundation for your engine's rotating assembly.

Carrillo has a long-standing reputation for making well-built connecting rods, and the Pro-H series is a popular choice for serious engine builds. They are forged from high-strength steel, which gives them the durability needed to withstand the higher cylinder pressures and RPMs often found in modified Porsche engines. The Pro-H beam design is a proven configuration that balances strength with a reasonable weight, crucial for maintaining engine balance and responsiveness. These rods use 3/8 inch CARR bolts, a robust fastener system that ensures a secure connection between the rod and cap under extreme loads. This attention to detail in materials and design means you can trust these rods to perform when you need them most.

When installing these rods, it's important to ensure your crankshaft journals are within the specified tolerances and that you use the correct torque sequence for the rod bolts. Proper assembly is key to unlocking the full potential and longevity of these components. These rods are designed as a direct replacement for the factory connecting rods in the specified Porsche models, making them a solid option for your engine project.
