Eagle Chevrolet 4.8/5.3 LS Pro Street Rotating Assembly 363 Cid 4.000in Stroke 6.125in Rod -5cc Dome

Eagle is a well-known name for building solid performance engine components, and this Pro Street rotating assembly is a prime example of their work for Chevrolet LS engines. If you're building a naturally-aspirated racing engine based on the popular 4.8L or 5.3L LS platform, this assembly is designed to handle the demands of the track. It's a complete package that brings together key rotating components to form the heart of your performance engine.

This assembly starts with a 4.000-inch forged 4140 crankshaft, providing a strong foundation for increased displacement. It's built for a 58-tooth reluctor wheel, common on many LS applications. Paired with the crank are 6.125-inch 4340 forged I-beam connecting rods, which are secured with 7/16-inch ARP 8740 bolts for reliable clamping force under high stress. The pistons are forged 4032 DSS flat-tops with a -5cc dome, designed to work with the 3.800-inch bore size and achieve a specific compression ratio when combined with the rest of your engine's components. The assembly also includes plasma-moly file-fit piston rings, which allow for precise gap setting to optimize sealing and performance. Finally, King XP rod and main bearings are included, offering robust lubrication and wear resistance for the critical journals.

This rotating assembly is intended for naturally-aspirated racing applications. Please note that this part is not CARB approved and cannot be shipped to California. It's crucial to consult your engine builder or refer to manufacturer specifications for proper installation and compatibility with other engine components to achieve your desired performance goals.
