SDPC Raceshop Mandrel Drive Kit

These kits are made for BBC to use almost any vacuum pump, fuel pump, alternator, dry sump, or other combination of race components. Simply drill your balancer to accept the included pins which prevent slippage at high load and bolt the assembly to your crank for dead center accuracy. Kit comes with 2 short spacers, 2 long spacers, a V-Drive pulley, keyed billet mandrel base, new balancer bolt, and pins.
