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.
