MSD - 8558
Distributor - Pro-Billet - Crank Trigger Pickup - Locked Advance - HEI Style Terminal - Red - Low Profile - GM W-Series - Each
Low-profile, tall block, racing distributor, must be used with an MSD 6, 7 or 8-series ignition and a crank trigger.
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.
