Supertech Nissan RB25/RB26 Conn Rod 4340 H-Beam C-C Length 121.5mm (4.783in) - Set of 6

If you're rebuilding the engine in your Nissan RB25 or RB26, especially for performance applications, you'll want to consider these Supertech connecting rods. They are a critical component that connects the piston to the crankshaft, translating the up-and-down motion into rotational force. For engines that see higher RPMs or increased boost pressure, upgrading from stock rods is often a necessary step to ensure reliability and prevent catastrophic failure.

These rods are forged from 4340 steel, a well-known material for its strength and durability, making them a solid choice for demanding builds. The H-beam design is also favored for its strength-to-weight ratio, offering robust support without adding excessive mass to the rotating assembly. With a center-to-center length of 121.5mm (4.783 inches), they are designed to be a direct replacement for the factory rods in RB25 and RB26 engines. This set includes six rods, enough for a complete engine build.

When installing these connecting rods, it's important to ensure proper balancing of the rotating assembly, including the pistons, rings, wrist pins, and the rods themselves. This helps to minimize vibrations and ensures the engine runs smoothly at all RPMs. Always refer to the manufacturer's installation instructions and torque specifications for proper assembly. These rods are a significant upgrade for anyone looking to build a reliable, high-performance RB engine.
