Supercharger Hardware

This complete replacement kit includes one allen wrench, five screws and a re-usable plastic plug for the supercharger shaft M8 hole.

There is an enormous load placed on the M8 screw during a pulley swap. Brighton-Best fasteners are among the finest available and hold up to the punishment.

Pulley Boys recommend using anti-seize on all threads and fresh M8 hardware for every pulley swap. Sold in sets of six, one washer is supplied with every M8 screw.

This will repair the M8 screws used in the puller kit without having to buy another complete puller tool.

• (6) M8 set screws (class 45H, 619 DIN)
• (6) M8 washers

This is for our Nissan qwikchange kit, these screws are too long to fit any non-Nissan qwikchange kit.

Most of the four groove Jackson Racing pulleys had a 0.8" offset, however a few of them had a 1" offset.

Because the 4 groove Jackson Racing pulleys we offer are the more common 0.8" offset, this 0.2" spacer must be used with our pulley if your system has the 1" pulley offset or your belts will slip.

If you aren't sure which offset measurement your Jackson Racing kit has then you may want to purchase this just in case or you will throw belts due to the 0.2" offset difference.
