Eagle Chevrolet 383 2 Pc 3.750in Stroke External Balance Cast Crankshaft

Performance crankshafts in forged steel or billet chromoly replace OEM cast iron crankshafts in high-output engine builds where the increased torque and RPM demand exceeds the fatigue strength of the factory part. A forged or billet crankshaft is the foundation of any serious engine build, setting the stroke, connecting rod journal size, and ultimately the displacement and power potential of the entire rotating assembly.Popular UpgradesStroker crankshafts for LS, small-block Chevy, small-block Ford, and Mopar applications are the most popular performance cranks, increasing engine displacement by extending the stroke beyond the factory specification. A 383 stroker crank for the 350 small-block Chevy and a 408 stroker crank for the 5.0 Ford are classic examples of displacement upgrades that provide significant torque increases without changing the engine block. Forged 4340 chromoly cranks rated for 1,000-plus horsepower are available for LS, LT, Coyote, and Hemi platforms for maximum-...

The crankshaft and its supporting components form the structural and mechanical core of every reciprocating internal combustion engine. Upgrading the crankshaft assembly with forged steel cranks, precision bearings, dampers, and timing components builds an engine bottom end capable of handling the power and RPM demands of a serious performance build.Popular UpgradesForged 4340 crankshaft sets paired with matching connecting rods, ARP main studs, and performance main bearings are the standard specification for any V8 performance build targeting 500 or more horsepower. Billet crankshafts for maximum-effort race applications provide the highest strength-to-weight ratio available when a forged crank's fatigue limit is a concern. Timing components including double-roller timing chains, billet steel gears, and cam phasers should be upgraded alongside any crankshaft swap to maintain proper valve timing under the increased loads of a performance build.What crankshaft components should be re...

Eagle Specialty Products has been a trusted manufacturer of high-performance forged and billet engine components for over 35 years, producing connecting rods, crankshafts, piston rings, and rotating assembly kits that engine builders rely on when stock parts are no longer adequate for the power level being chased. The brand's 4th generation H-beam connecting rods, known as the 4D design, address the most common failure points in previous-generation rods by increasing big-end rigidity through thicker webbing and an improved beam profile that resists bending under high cylinder pressure. Eagle rods are 100 percent CNC machined from 4340 chromoly steel, include ARP 2000 rod bolts as standard, and are popular for both street-strip builds and dedicated track-day engines on a range of domestic V8, LS, and sport compact platforms. Builders who want proven rotating assembly reliability without custom billet pricing consistently choose Eagle as their go-to rod supplier.Popular UpgradesEagle'...

This engine parts collection covers oil catch cans, thermostats, thermostat housings, radiator components, coolant accessories, engine covers, fuse box covers, cap covers, throttle bodies, supercharger pulleys, idler pulleys, tensioner pulleys, and engine bay dress-up parts for trucks, SUVs, muscle cars, boosted builds, high-horsepower street cars, and performance vehicles that need better reliability, cooling, airflow, oil control, and under-hood styling. The collection is particularly strong for Dodge Challenger, Charger, Durango, Jeep Grand Cherokee Trackhawk, and Ram TRX platforms running 6.2L Hellcat, 6.4L HEMI, and 5.7L HEMI engines, where oil catch can and cooling upgrades address known OEM weaknesses in the PCV and thermal management systems. Import performance platforms including GM LS-based builds, Chevrolet Camaro, and Corvette applications are also represented through Mishimoto, CSF, and ZPE GripTec product lines. Builders who invest in engine bay organization and reliab...
