Carrillo Nissan/Infinity/Datsun RB25/RB26 Pro-H 3/8 CARR Bolt Connecting Rods

If you're building a high-performance Nissan RB25 or RB26 engine, these Carrillo Pro-H connecting rods are a solid choice. Carrillo has a long-standing reputation for making some of the strongest connecting rods available, and this set is designed to handle the demands of serious engine builds. They are specifically made for RB25 and RB26 engines, ensuring a proper fit for your project.

These rods feature Carrillo's Pro-H beam design, which is a strong, lightweight I-beam profile that offers excellent strength-to-weight ratio. This means they can withstand higher cylinder pressures and RPMs without adding unnecessary mass to your rotating assembly. They use 3/8 inch CARR bolts, which are a robust fastener choice for securing the rod cap. The material is a high-grade steel alloy, heat-treated for maximum durability and fatigue resistance. This level of construction is crucial when you're pushing an engine beyond its stock limits, whether for track use or a powerful street machine.

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. These are not a simple bolt-on replacement for stock rods; they are part of a performance engine build. You'll want to pair them with appropriate pistons and ensure your block and crank are prepped correctly. This set includes six connecting rods, ready for your custom engine build.
