Intended for the most demanding applications. Billet 4340 Steel Crank - NISSAN SR20, 3.583" Stroke, KNIFE-EDGED COUNTERWEIGHTS. Crankshaft must be balanced to match your specific Rods and pistons. NISSAN SR20

The Eagle Nissan SR20 4340 Billet Crankshaft is engineered for demanding high-performance and competition applications. Manufactured from premium 4340 billet steel, this crankshaft uses knife-edged counterweights to reduce rotating weight and improve engine response. Its 3.583-inch stroke is designed for Nissan SR20 engine builds requiring increased displacement and durable bottom-end performance.

Strength and surface durability are enhanced with .125-inch fillet radiuses, a nitrided surface, and a micropolished finish. Because the larger fillet radiuses require additional clearance, chamfered or narrowed main and rod bearings are required during installation. The crankshaft must be professionally balanced to match the exact connecting rods and pistons used in the engine assembly.

This Eagle crankshaft is intended for automotive use and is not intended for street emissions certification. Professional engine machining and assembly are recommended to verify bearing clearance, crankshaft alignment, balance, and compatibility with the complete rotating assembly. Fitment is intended for Nissan SR20 applications; confirm engine configuration and required supporting components before purchase.
