If you're diving into the world of racing and need a solid foundation for your engine, the Eagle Competition Rotating Assembly is where it’s at. Eagle really knows how to put together a package that balances performance, reliability, and durability without emptying your wallet. This assembly is built for those who want to push their engines to the limit, whether you’re running exotic fuels, nitrous, or forced induction setups. It's like having a secret weapon in your corner.

Now, let’s break down what you’re getting here. The assembly features a 3.400" forged 4340 crankshaft, which is tough enough to handle the heat of competition. Pair that with 5.400" H-Beam rods made from forged 4340 steel, and you’ve got a setup that’s built to last. Each rod is secured with 7/16" ARP 8740 bolts, so you know they’re not going anywhere. The pistons are forged 4032 Mahle flat tops with a -6cc dome volume, giving you a solid compression ratio for those high-octane runs. Plus, the plasma-moly file fit rings ensure a tight seal, which is crucial for keeping everything running smoothly under pressure.

Features

  • Assembly Balanced: Yes, because nobody likes a shaky engine.
  • Balance Type: Internal, for that smooth operation.
  • Connecting Rod Bolt Diameter: 7/16", sturdy enough for serious power.
  • Connecting Rod Design: H-Beam, which means strength without the extra weight.
  • Connecting Rod Length: 5.400", perfect for a variety of builds.
  • Crankshaft Material: Forged 4340 steel, built to take a beating.
  • Crankshaft Stroke: 3.400", giving you the right kick for those high RPMs.
  • Cylinder Bore Diameter: 4.125", fits nicely with a lot of aftermarket setups.
  • Main Bearings Included: Yes, so you’re ready to roll right out of the box.
  • Piston Brand: Mahle, because quality matters.
  • Piston Pin Type: Full floating, which helps with the smooth operation of the engine.
  • Piston Ring Gap: File fit, ensuring you get a tight seal.
  • Oil Rail Support Included: Yes, keeping everything lubricated is key.

Notes:

Clearance: You might need to do a little trimming on your block for a perfect fit, and an aftermarket block is recommended for best results.

Universal Fitment: While this assembly is designed to fit a range of applications, it's always a good idea to do your homework to ensure compatibility with your specific setup.

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.
