Eagle Specialty Products Competition Assembly Chevrolet LS3 - 129524125

If you're diving into the world of racing, you know that every little detail counts, and that's where the Eagle Competition Rotating Assemblies come into play. These assemblies are built for serious performance, whether you’re running nitrous or cranking up the boost with forced induction. Trust me, they’ve got the chops to handle whatever you throw at them.

Let’s talk specs. You’re looking at a 4.125” forged 4340 crank that’s not just tough but built to last. It comes with a 58-tooth reluctor for precise timing, and those 6.125” H-beam rods are no joke—strong enough to handle high revs without breaking a sweat. Plus, they’re secured with 7/16” ARP 8740 bolts, so you know everything is held together tight.

Now, let’s get to the heart of the assembly: the forged 4032 Mahle -8CC flat top pistons. These bad boys are designed for performance, giving you the right compression while keeping weight down. And with plasma-moly file fit rings, you’re ensuring a tight seal that helps with efficiency and power. Don’t forget about the King XP rod and main bearings—they’re built for durability and can handle the heat of racing without flinching.

  • Assembly Type: Competition Assembly
  • Bore: 4.125
  • Piston Brand: Mahle
  • Piston Type: Flat Top Forged
  • Product Line: Competition
  • Prop 65: Yes (check the label)

Just a heads up: you’ll need to have this assembly balanced by a qualified machine shop before you hit the track. It’s a crucial step that can’t be overlooked if you want everything running smoothly.

As for fitment, these assemblies are designed with a universal fit in mind, but it’s always a good idea to do your homework to ensure they’ll work with your ride. A little research goes a long way in confirming compatibility with your vehicle—especially if you’re working with a Chevrolet LS3.

In short, if you’re serious about performance and want to push your ride to the limit, the Eagle Competition Rotating Assemblies are definitely worth considering. They’re built for the track and ready to deliver when it counts.

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.
