Hot Rods Crank Pin - 16 x 30

This is a Hot Rods crank pin, measuring 16 x 30 millimeters. It's a key component for rebuilding or working on the crankshaft assembly in many engines. When you're putting an engine back together, especially for performance applications or a full rebuild, the crank pin is what connects the connecting rod to the crankshaft. It needs to be strong and precisely sized to handle the forces involved.

Hot Rods makes these pins from hot-rolled ASTM 4115 steel, which is a solid choice for this kind of part. After forming, they're case-hardened to a hardness of 58-62 Rc. This process makes the outer surface very hard to resist wear and deformation from the constant motion and pressure, while the inner core remains a bit tougher to absorb shock. This combination is important for ensuring the longevity and reliable operation of your engine's bottom end.
