If you're serious about performance, you probably already know that the heart of your engine is the connecting rods. Enter the Eagle Specialty Products Forged 4340 Steel H-Beam Connecting Rods. These beauties are forged from 4340 steel, which is known for its strength and durability. Trust me, when you’re pushing your engine to the limits, you want rods that can handle the heat and the stress without flinching.

These rods are not just any ordinary rods. They come as a weight-matched set, which is crucial for maintaining balance in your engine. The last thing you want is for one rod to be heavier than the others, causing vibrations and potential damage. Each rod is precisely machined and shot-peened, which not only enhances their strength but also helps with fatigue resistance. So, whether you're hitting the track or just want to ensure your daily driver can handle a bit more power, these rods are up for the task.

Let’s talk numbers. The center bore to center bore length is 140.5 mm, and they feature a pin size of 21 mm. If you’re running custom pistons, these rods are a solid choice since they’re longer than your stock ones. Just keep in mind that they’re recommended for competition use, so you know they’re built to perform.

Who is EAGLE?

EAGLE SPECIALTY PRODUCTS, aka EAGLE, has been at the forefront of developing top-quality engine components. The company officially started back in 1992 but has been developing their product for ten years prior.  Since the company started, it has continuously produced some of the market's best engine components and is widely used by engine builders worldwide.

Imitated But Not Duplicated

Due to the company's success, its products have been imitated by other companies even up to the part numbers. But the similarity ends only up to how they look. EAGLE uses the finest materials and has invested in the most state-of-the-art manufacturing machinery for them to create a product that would be able to take any punishment it is subjected to. It is tested to be superior to other brands and considered the best upgrade for OEM counterparts.

No To Shortcuts

The company sets the benchmark on how valves should be properly made. Using their years of experience creating rods, they have already designed over 200 different rods and 180 crankshafts. The company does not allow cost to compromise its material used, manufacturing process, and quality test. 

High-End Quality

All of Eagle's products are made up of high-quality materials. They use certified 4340 Chromoly steel. Using their own special heat treatment process, they are able to create a product that is much stronger compared to other competitors using the same raw material. 

They manufacture their rods using a 2-piece forging process that allows the rod to be stronger. This process orients the "grain" of the metal to the direction of the stress. Eagle uses a state-of-the-art Sunnen Krossgrinding system that allows them to create perfect cuts and bore consistently.
