Hot Rods Crank Pin - 10 x 24.3 x 48

This crank pin is made from hot-rolled ASTM 4115 steel, a strong material chosen for its ability to withstand the stresses of engine operation. It's then case-hardened to a hardness of 58-62 Rc, which means the outer surface is made much tougher and more resistant to wear than the core. This process is important for components like crank pins that experience constant rotational forces and potential impacts within the engine.

The specific dimensions of 10mm x 24.3mm x 48mm are critical for ensuring it fits precisely where it needs to go in your crankshaft assembly. A well-made crank pin is essential for the smooth and reliable operation of your engine, as it connects the connecting rod to the crankshaft, transferring power through the drivetrain.
