ACCEL Street Billet performance electronic breakerless distributors are built with a new CNC billet 2-piece housing with a precision, centerless-ground steel shaft. The shaft runs on upper and lower oilite bushings to accurately locate the steel alloy drive gear for a lifetime of reliable performance. Their ACDelco-style, top mount, stainless steel mechanical advance is easy to adjust. The heart of these distributors is their performance 12 V breakerless 6.5 amp dwell-control module. They also feature an adjustable vacuum advance, an easy 3-wire hookup, and an ACCEL performance cap and rotor.
