Eagle Specialty Prod 4340 H-BEAM Rod 5.700" 2.100 Rod - CRS5700B3D-1

If you're diving into the world of performance engines, you know that the right connecting rods can make or break your build. Let me tell you about the Forged 4340 Steel H-Beam Connecting Rods—these bad boys are designed for serious competition use and can handle the heat when you're pushing your engine to its limits.

Crafted from forged 4340 steel, these rods are built tough. The two-piece forging process gives them a solid structure, and the fully machined and shot-peened surface ensures they’re not just tough but also precise. We're talking about tight tolerances here, so you can count on them to fit just right in your setup. When you order, make sure to specify the weight you need; it’s all about getting that balance just right.

Now, let's get into the nitty-gritty. These rods are specifically made for Chevrolet Small Block engines with a length of 5.700 inches. The big end width is a solid 0.94 inches, which means they can handle some serious power without flexing. And those 7/16" ARP 8740 bolts? They’re the real deal—strong and reliable, just what you want when you’re cranking up the torque.

One of the standout features is that they’re bushed for full-floating piston pins. This allows for smoother operation and less wear on your components, which is crucial when you’re chasing performance. The pin end width is 1.06 inches, and the pin size comes in at 0.927 inches. Plus, with a rod journal size of 2.1 inches, you’re looking at a setup that can handle some serious RPMs.

Don't forget to torque these rods to 63 ft-lbs using ARP moly lube—trust me, it makes a difference. And while these rods are pretty universal in fitment, it’s always a good idea to do your homework and make sure they’ll work for your specific vehicle. A little research goes a long way in ensuring you get the right gear for your engine.

In short, if you're looking to boost your engine's performance, these ESP 4340 H-Beam Rods are a solid choice. They’re tough, reliable, and designed for the kind of power you want to unleash. Just make sure you’re ready to put them to the test!

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.
