Hemi Products Distributors

Our distributors are specially designed to ensure maximum accuracy and precision when controlling the high voltages and tight tolerances the ignition system in a high performance Hemi engine requires. Please call for a quote to add this or any other part to your order.

What You Should Know About Distributors

The distributor is a critical device in a high performance Hemi engine. Within the ignition system of these extreme performance, internal combustion engines, the distributor routes high voltage from the ignition coil to the spark plugs in the correct firing order.

The distributor shaft has a cam that operates the contact breaker. Opening the points produces a high induction voltage in the system's ignition coil.

The distributor also houses the centrifugal advance unit: a set of hinged weights attached to the distributor shaft, that cause the breaker points mounting plate to slightly rotate and advance the spark timing with higher engine rpm. In addition, the distributor has a vacuum advance unit that advances the timing even further as a function of the vacuum in the inlet manifold. Usually there is also a capacitor attached to the distributor. The capacitor is connected parallel to the breaker points to suppress sparking and prevent wear of the points.

Providing proper performance of these parts in a Real Hemi engine requires materials and manufacturing techniques more refined than those for a standard automobile engine. That is why the distributors we carry are only of the highest quality.
