If you're looking to breathe new life into your engine without going down the rabbit hole of reworking your stock parts, the Eagle Street & Strip Rotating Assembly is a solid choice. I’ve had my hands on these assemblies, and I can tell you, they strike a great balance between cost and quality. Designed for naturally-aspirated, pump gas street engines, they really do the job without breaking the bank.
This assembly features a 3.750" cast crank that’s tough enough to handle the daily grind, paired with 5.700" I-Beam rods that are built from forged 5140 steel. You’ll also find 3/8" ARP 8740 bolts holding everything together, which is a nice touch for added durability. The hypereutectic KB -7cc flat top pistons come in at a bore diameter of 4.030", and they’re designed to give you that extra punch while keeping things reliable. Plus, the plasma-moly standard gap rings and King SI rod/main bearings round out the package nicely.
Universal Fitment: This assembly is designed to fit a variety of vehicles, but it’s always a good idea to double-check your application to make sure it’s the right fit for your ride.

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 DuplicatedDue 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 ShortcutsThe 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 QualityAll 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.
