The Eagle Specialty Products 4350348057CM is a high-strength crankshaft forged from 4340 steel, engineered for Chevrolet 305/350 engines and specifically designed for IMCA RaceSaver racing. It boasts a non-twist forging and .125-inch fillet radii, enhancing its overall durability and performance under demanding conditions. This crankshaft requires chamfered or narrowed bearings due to its robust construction. Key features include a nitrided surface treatment and a micropolished finish for optimal smoothness and longevity. Unlike some other designs, this crankshaft deliberately omits lightening holes in the second and third rod throws to maximize structural integrity. It is crucial to note that this crankshaft must be professionally balanced to precisely match your specific connecting rods and pistons to ensure optimal engine operation and prevent potential damage. Installation services are available from JB's Power Centre in Calgary and Edmonton, AB, with licensed Mechanical Technicians on staff. Additionally, Eagle Specialty Products offers fast shipping, with potential for next-day delivery depending on your location, and provides tracking information for all purchases.
