What is the purpose of shot-peening these connecting rods?

Shot-peening is a process that bombards the surface of the metal with small beads. This creates compressive residual stresses on the surface, which helps to increase the rod's fatigue strength and resistance to cracking, especially under high-stress conditions.

Are these rods suitable for a stock LS engine rebuild?

While these rods are recommended for competition use due to their robust construction, they can be used in high-performance street builds. For a stock rebuild, ensure your build plan accounts for the increased strength and potential modifications needed for such components.

What does it mean that the rods are 'weight-matched'?

Weight-matched means that each connecting rod in the set has been precisely weighed and balanced to be within a very small tolerance of each other. This is critical for engine balance, reducing vibration, and ensuring smooth operation, especially at high RPMs.

About this part

Product Details

Eagle is well-known for making strong internal engine components, and these forged 4340 steel H-beam connecting rods are a prime example. Designed for Chevrolet LS engines, these rods are built to handle the demands of performance builds. They measure 6.460 inches in length and feature a 1.889-inch rod journal size, making them a direct fit for a wide range of LS applications, including popular models like the Chevrolet Camaro, Corvette, and Pontiac GTO.

These rods start as a two-piece forging made from 4340 steel, a material chosen for its excellent strength and durability under high stress. After forging, they undergo a complete machining process and are shot-peened. This shot-peening process helps to relieve internal stresses in the metal, which significantly improves the rod's fatigue life, especially important for competition use. Eagle holds the sizing to exact tolerances, ensuring that each rod in the set is weight-matched. This attention to detail is crucial for engine balance and smooth operation at higher RPMs. They come equipped with ARP 2000 bolts, known for their reliability and clamping force.

This set includes eight weight-matched rods, ready for installation in your LS engine. While recommended for competition use, their robust construction also makes them a solid choice for high-performance street engines where reliability and strength are paramount. Ensure you consult your engine builder or service manual for specific installation procedures and torque specifications.
