Powerdyne Supercharger full rebuild kit. This parts kit includes the following parts and upgraded components to fit BD11a and BD11r.
- Quantity 2 SKF input bearings.
- Quantity 2 SKF ceramic output bearings.
- Quantity 1 Gates HTD kevlar replacement belt.

The bearings are an upgrade over stock. These parts are the correct RPM, load, and temperature rating for this supercharger. Do NOT install just any bearing in this area. Permanent failure will result in the use of a cheap, low RPM bearing that are sold by others. The output shaft bearings are rated for over 60,000 RPM. Maximum recommended supercharger RPM is 42,500 rpm due to other engineering factors involved. Replacement belt is 3mm wider than stock for more strength. Belt does not require modification.
