Eagle Cavalier 2.2 ECO Extreme Duty Connecting Rods (Set of 4)

Eagle is well-known for building strong engine components, and these Cavalier 2.2 ECO Extreme Duty Connecting Rods are a prime example of their commitment to performance. If you're building a high-output 2.2L Ecotec engine for serious competition, these rods are designed to handle the extra stress.

These rods are forged from 4340 steel, a material chosen for its excellent strength and durability under high loads. They feature an H-beam design, which offers a good balance of strength and weight, making them suitable for demanding applications. The manufacturing process includes a two-piece forging, followed by full machining, shot-peening, and polishing. Shot-peening is a critical step that adds a layer of internal stress to the metal, significantly increasing its fatigue life and resistance to cracking under extreme pressure. The polished surface further reduces stress risers.

For fastener strength, Eagle uses ARP Custom Age 625+ bolts. These are among the strongest bolts available, ensuring the rod caps stay securely in place even under immense cylinder pressures. The set is weight-matched, meaning each rod in the set is precisely balanced to within exact tolerances. This is crucial for engine balance and longevity, especially in high-RPM applications. These rods are intended for extreme competition use, so they represent a significant upgrade over stock components for those pushing their 2.2L Ecotec engines to the limit.
