Hot Rods Crank Pin - 8 x 22 x 53

This is a Hot Rods crank pin, measuring 8 x 22 x 53 millimeters. It's crafted from hot-rolled ASTM 4115 steel, a strong material chosen for its reliability in engine components. The pin is then case-hardened to a hardness level of 58-62 Rc, which significantly increases the surface durability and resistance to wear.

This hardening process is crucial for parts like crank pins that experience constant stress and friction within the engine. By making the outer surface harder, it can better withstand the forces involved in rotating the crankshaft, helping to ensure a longer service life for your engine's internal components. The specific dimensions, 8mm inner diameter, 22mm outer diameter, and 53mm length, are designed for precise fitment in compatible engine assemblies.
