If you have a cold shock camshaft that needs to be replaced, you can get one of the cold shock camshaft blanks from Zhejiang Junrong Auto Parts. These camshafts are manufactured using tool steel that has been heat treated. The type of heat treatment used will determine the range of spec that the blank should be.
Camshaft blanks are pre-heated and custom-ground for an optimal cam lobe profile. They come as either intake or exhaust cams and are designed to work in natural and forced induction systems. Listed on the back are the intake lift and exhaust lift for each cam.
Cold shock camshaft blanks can be ground or machined. However, they cannot be used to make camshafts with complex shapes. The cold depth of a chill cast camshaft blank depends on two key factors: the width and the top height of the cam. A broad width facilitates the formation of a thicker cold shock layer.
