Eagle Chevrolet 400 ARP L19 Bolts Forged 4340 Steel H-Beam Rods - Set of 8

Forged from 4340 steel, these H-beam connecting rods from Eagle are built for serious performance applications, specifically for Chevrolet 400 engines. The H-beam design offers a strong yet lightweight profile, crucial for handling the stresses of high-RPM operation and increased power output. Each rod is machined from a two-piece forging, ensuring consistent dimensions and a fully machined and shot-peened surface for improved fatigue life. This attention to detail means the sizing is held to exact tolerances, which is vital for proper engine assembly and long-term reliability.

What really sets these rods apart is the inclusion of ARP L19 bolts. These are high-strength fasteners designed to handle extreme cylinder pressures and detonation, making them ideal for competition use where reliability under immense stress is paramount. The rods are sold as a weight-matched set of eight, meaning each rod in the set is within a very close weight tolerance. This is critical for engine balance, reducing vibration and ensuring smoother operation, especially in high-performance builds. If you're building a powerful Chevrolet 400 for racing or extreme street use, these rods are a solid choice for handling the power.
