Carrillo Honda/Acura K20A Pro-H 3/8 CARR Bolt Connecting Rods

Forged from aircraft-grade 4340 steel, these Carrillo Pro-H connecting rods are built to handle the stresses of a high-performance K20A engine. The 3/8 inch CARR bolts are a key feature, offering a robust connection point designed for engines that see hard use. If you're rebuilding the bottom end of your 2002-2006 Acura RSX or 2002-2005 Honda Civic for more power, these rods are a solid choice.

Carrillo is well-known for making strong internal engine components, and these rods are no exception. They use a proprietary heat-treating process that makes the steel even stronger and more resistant to fatigue, which is crucial when you're pushing an engine beyond its stock limits. The I-beam design is a classic for a reason – it balances strength with weight, helping to keep reciprocating mass down while maintaining structural integrity. This means the engine can rev more freely and reliably under load.

When you're building an engine that needs to perform, the connecting rods are one of the most critical parts. These Carrillo rods are designed to be a direct replacement for your stock rods, but with a significant upgrade in strength and durability. They come with the necessary 3/8 inch CARR bolts, so you'll have the essential hardware to get them installed. Make sure to follow the manufacturer's installation instructions carefully, especially regarding bearing clearances and torque specifications, to ensure optimal performance and longevity.
