If you're looking to breathe new life into your engine without diving into the deep end of a full rebuild, the Eagle Street & Strip Rotating Assembly is a solid option. Instead of messing around with old, worn-out parts, Eagle has put together a kit that combines quality with affordability. This assembly is particularly well-suited for naturally-aspirated, pump gas street engines. I've had my fair share of tinkering, and I can tell you that this setup really strikes a balance between performance and practicality.

Now, let’s get into the nitty-gritty. This rotating assembly features a 4.250" cast crank that’s built to handle the demands of street driving while still giving you that extra oomph when you hit the gas. The 6.385" I-Beam rods are made from forged 5140 steel, which means they’re tough enough to take a beating without bending. Plus, the ARP 8740 bolts (7/16" diameter) keep everything nice and secure. The pistons are forged 4032 aluminum from Mahle, with an 18cc dome that fits a 4.310" cylinder bore. And let’s not forget about the plasma-moly file-fit rings, which are a game changer for ensuring a snug fit and better performance.

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.
