232-258 CI HEI Distributor DUI, 1971-1978, Commando, CJ5, CJ6, CJ7

Our DUI Distributor is one of the best selling ignition systems we offer. This is due to the simple one piece design, easy installation and performance enhancements over a stock ignition system. The all-in-one DUI replaces the weak three component system that came standard on the AMC engines and utilizes only one 12 volt hot wire for hookup. The DUI is equipped with an internal 50,000 volt coil, which will fire a spark plug gap as large as .055″! Our high dwell Dyna-Module, located inside the distributor, increases spark duration for improvements in throttle response and low end power. The DUI centrifugal advance system is a true Performance Distributors specialty. We use a high performance weight and spring assembly engineered for super smooth operation. The mechanical advance is then tuned using a Sun distributor machine to ensure a precise timing curve that will provide maximum power throughout the RPM range while eliminating engine damaging detonation.
