    Features & Benefits

    The unique design of these distributors fit tight intake systems while still transferring the high voltage of the MSD racing ignition to the spark plugs. The high voltage carrying capabilities are the result of several features which have been designed into these low-profile distributors. This includes a large diameter cap with wide spaced terminals and an injection molded Rynite rotor with thick vanes to stir up the air inside the cap. The high dielectric Rynite base also prevents arcing to the billet housing. Since these distributors are used primarily in racing applications, an oversized steel shaft is responsible for delivering the sparks. This shaft is QPQ coated for friction reduction and receives guidance from a sealed ball-bearing assembly and an extra long, precision sintered bushing for smooth operation. Note: must be used with an MSD crank trigger and ignition control.

    • Designed to fit low in the block to clear firewall and intake combinations
    • CNC machined billet aluminum housing and Dupont Rynite base
    • Adjustable slip collar mounting flange for engines with modified deck heights
    • Oversized polished steel shaft with a QPQ coating for friction reduction
    • Shaft is guided by a sealed ball bearing and an extra long sintered bushing
    • Special oil tract improves lubrication to the distributor and cam gear
