Carrillo Nissan/Infiniti/Datsun TB48 Pro-H 3/8 WMC Bolt Connecting Rods

If you're building a high-performance Nissan, Infiniti, or Datsun with the TB48 engine, these Carrillo Pro-H connecting rods are a solid choice for the core of your engine. Carrillo has a long-standing reputation for making well-built internal engine components, and these rods are designed to handle the stresses of boosted or high-RPM applications where stock components might not hold up.

These rods are forged from high-strength steel, a common practice for performance connecting rods because it creates a strong, reliable part that can withstand significant cylinder pressures and reciprocating forces. They feature Carrillo's Pro-H beam design, which is a popular choice for its balance of strength and weight. This design helps keep rotating mass down, which is important for engine responsiveness and durability under load. The rods come equipped with 3/8" WMC bolts, which are a robust fastener choice for connecting rod applications, ensuring a secure and strong assembly at the big end. This specific part number, SCR5444-6, is for a set of six connecting rods, as required for a 6-cylinder TB48 engine.

When installing these, it's crucial to follow the manufacturer's recommended torque specifications for the rod bolts and to ensure proper bearing clearance. Using a quality engine assembly lubricant is also highly recommended during the build process. These rods are a significant upgrade for anyone looking to push their TB48 engine beyond its original specifications.
