Carrillo Chevy Small Block Gen III/IV 6.125in Pro-H 3/8 CARR Bolt Connecting Rods (Set of 8)

If you're building a high-performance Chevy Small Block Gen III or IV engine, getting the connecting rods right is crucial for handling the power you want to make. These Carrillo Pro-H rods are built for serious performance, designed to handle the stresses of boosted or naturally aspirated builds that push beyond stock capabilities. They feature a robust Pro-H beam design, which is a strong, lightweight I-beam profile that Carrillo is well-known for, offering excellent strength-to-weight ratios.

Each rod in this set of eight is forged from high-grade alloy steel, then heat-treated for maximum durability. They come equipped with Carrillo's own 3/8" CARR bolts, which are specifically designed to handle the high clamping forces and dynamic loads found in performance engines. The 6.125-inch length is a common and effective length for many Chevy LS-based applications, and the 2.100-inch journal size is standard for these engines. These rods are a popular choice for builders looking for a well-made, reliable component that won't be a weak link in their engine build. They fit a wide range of GM vehicles, including models like the Chevrolet Corvette, Camaro, and Pontiac GTO.

When installing these rods, it's important to ensure your crankshaft journals are within the specified tolerances and that you follow proper assembly procedures, including correct torque values for the rod bolts. Using a quality lubricant during assembly is also key. These rods are a solid foundation for an engine that needs to perform reliably under demanding conditions.
