Eagle Specialty Products 435338756000 4340 Forged Steel Crankshaft Chevy 350 3.875" Stroke

The Eagle Specialty Products 435338756000 is a high-performance forged 4340 steel crankshaft designed for small block Chevrolet 350 applications. Engineered with a 3.875-inch stroke, this one-piece rear main seal crankshaft is ideal for building stroker engines up to 383 cubic inches when paired with standard bore dimensions.

Key Features:

• Forged from premium 4340 steel for exceptional strength and durability
• 3.875-inch stroke for increased displacement and torque
• One-piece rear main seal design for compatibility with late-model blocks
• Precision-machined journals for optimal bearing fit and reduced friction
• Micropolished fillets to minimize stress concentrations and prevent cracking
• Nitrided surface treatment for enhanced wear resistance
• Fully counterweighted and balanced for smooth operation
• Compatible with standard 5.7-inch connecting rods

This crankshaft is manufactured to exacting tolerances using advanced forging techniques, making it suitable for high-performance street applications, drag racing, and other demanding motorsports use. The 4340 steel construction provides superior strength-to-weight ratio compared to cast cranks, while the extended stroke increases engine displacement and low-end torque output.
