BPS supercharger pulleys are stock look and made of high grade steel. Precision machined bore. Press fit just like OEM. Machined to OEM specs. All pulleys are powdercoated for a nice and long lasting finish.
Engineering and Manufacturing Note: The final manufacturing step is honing the bore to achieve the best fit which is .0002 tolerance. This ensures that the bore is perfectly straight.
It is strongly recommended to pair this up with a BPS Auxiliary Idler Bracket to provide superior belt wrap.
