Bracket swings off the driver (1, 3, 5, 7) or passenger (2, 4, 6, 8) side and uses a heat-treated steel driveshaft that uses a .625" shaft on one side with a .187" keyway and two flats machined so a racer can tighten the pulley set screws to insure the pulley doesn't move on the shaft after installation. The other side of the shaft uses a female .375" hex to drive the fuel pump or the cable cam speed off the crankshaft. Shaft rides in a sealed hi-speed ball bearing.
Mount bracket hangs off a .375" stud or bolt from the top and racer can swing the bracket and use one of the lightening slots to lock the bracket down to keep drive belt tight. From center of top mount hole to center of fuel pump drive shaft is 4.50" and adjustment slot is 2.00" to give the racer plenty of belt adjustment. Bracket is made from billet .500" alum. that has been anodized for corrosion protection.
Racer can choose driver (1,3 5, 7) or passenger (2, 4, 6, 8) side bracket from drop down menu.
