Eagle Chevrolet LS 6.560in Length ARP L19 Bolts Forged 4340 Steel H-Beam Rods - Set of 8

This set includes eight Eagle H-beam connecting rods, forged from 4340 steel, along with ARP L19 bolts. These rods are specifically designed for Chevrolet LS engines and measure 6.560 inches in length. The H-beam design is a popular choice for performance applications because it offers a strong yet relatively lightweight profile, making it well-suited for handling increased cylinder pressures and RPMs found in modified or high-performance LS builds.

The 4340 forged steel construction is a significant upgrade over factory cast rods, providing enhanced durability and resistance to fatigue under demanding conditions. This material is known for its excellent strength-to-weight ratio. The inclusion of ARP L19 bolts is notable; L19 is a high-strength alloy steel specifically formulated for high-performance engine applications, offering superior clamping force and tensile strength compared to standard ARP bolts. These rods are built to handle the stresses of boosted engines, nitrous oxide, or aggressive naturally aspirated setups. The 6.560-inch length is a common specification for many LS engine configurations, ensuring proper piston-to-valve clearance and geometry when paired with appropriate crankshafts and pistons.

When installing these connecting rods, it's crucial to ensure proper balancing of the rotating assembly. While these rods are well-built, their performance is maximized when the entire assembly—crankshaft, pistons, rings, and rods—is balanced by a professional machine shop. Always refer to the manufacturer's installation instructions for specific torque specifications and any recommended assembly procedures to ensure optimal performance and longevity.
