Eagle Specialty Products Heavy Duty Assembly Ford 289 / 302 - 34051030

If you’re diving into the world of extreme engines, the Eagle Heavy Duty Rotating Assemblies are where it's at. I’ve been around the block with these, and let me tell you, they’re built to handle some serious competition. Whether you’re running exotic fuels, cranking up the nitrous, or pushing high boost, this assembly doesn’t flinch.

Let’s break it down a bit. You’ve got a 3.250” forged 4340 crank that’s tough enough to take the punishment you’re dishing out. Pair that with 5.400” H-beam rods, and you’ve got a setup that can handle the heat. The 7/16” ARP 2000 bolts? Yeah, they’re not messing around either—these babies are designed for serious strength.

Now, the pistons are where things get interesting. We’re talking about Forged 2618 JE -5CC heavy-duty flat-top pistons with a 4.030” bore. These aren’t your run-of-the-mill pistons; they’re crafted to withstand the intense conditions of high-performance racing. Plus, the plasma-moly file fit rings ensure a snug fit, keeping everything sealed tight under pressure. And let’s not forget the King XP rod and main bearings—these are a solid choice for ensuring your engine runs smoothly.

  • Assembly Type: Heavy Duty Assembly
  • Bore: 4.03 inches
  • Piston Brand: JE
  • Piston Type: Heavy Duty Flat Top Forged
  • Product Line: Heavy Duty
  • Prop 65: Yeah, there’s a warning—make sure you check it out.
  • Title: ESP Heavy Duty Assembly for Ford 289 / 302
  • Note: Assembly must be balanced by a qualified machine shop before use!

These assemblies are pretty universal, which is great, but I’d still recommend doing your homework to ensure they fit your setup. You don’t want to get halfway through a build only to find out something doesn’t line up. If you’re in the market for a robust assembly that’s ready to take on whatever you throw at it, the Eagle Heavy Duty Rotating Assembly for the Ford 289 / 302 is a solid bet.

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.
