Carrillo Honda/Acura B18A/B18B/B20B Pro-A 5/16 WMC Bolt Connecting Rods (Special Order No Cancel)

The 5/16" WMC bolts used in these Carrillo Pro-A connecting rods are a key detail for anyone building a high-performance B-series engine for their 1990-2001 Acura Integra or 1997-2001 Honda CR-V. These rods are built to handle significantly more stress than stock components, making them a solid choice for boosted applications or aggressive naturally aspirated builds. Carrillo has a long-standing reputation for making well-built internal engine components, and these rods are no exception.

Crafted from high-strength steel, these connecting rods are designed to be a robust upgrade over the factory parts. The Pro-A series features a specific beam design that balances strength with weight, which is crucial for engine balance and responsiveness. The 5/16" WMC bolts are a step up from standard hardware, offering improved clamping force and durability under high RPM and cylinder pressure conditions. This attention to detail in materials and design means these rods can reliably transmit power from the pistons to the crankshaft, even when pushed hard.

When you're investing in internal engine components like connecting rods, it's important to consider the entire build. These rods are intended for serious engine work, so ensure your crankshaft, pistons, and bearings are also up to the task. Because these are a special order item, please confirm your order carefully before submitting, as cancellations are not possible. This is a critical component for anyone serious about extracting reliable power from their B18A, B18B, or B20B engine.
