Performance Distributors 52720 DUI Distributor in Black for 80-81 Jeep® CJ-5, CJ-7 & CJ-8 Scrambler with 2.5L I4 Engine

Catalog #: 55102.608
Performance Distributors Part #: 52720
The D.U.I. is a one-piece ignition system with the coil in the distributor cap and the module inside the distributor. The D.U.I. Coil produces 50,000 volts and allows spark plug gaps to be opened up to .050” -.055”. The Performance Distributors Dyna-Module has more electronic dwell time in it to give the coil more saturation time to produce a hotter spark. The D.U.I. distributor eliminates the ballast resistor that is used on the stock AMC ignition system to allow full alternator voltage through the ignition system, allowing better spark and more power. Each D.U.I. Distributor is curved on a distributor machine based on the specs of the engine. A supersmooth advance curve eliminates potential engine-damaging detonation and gives instant throttle response.

Our Street/Strip D.U.I. Distributors are custom-calibrated for your particular application. Every unit is curved on a distributor machine, blueprinted and precision built. All of the OEM and aftermarket manufacturers make distributors on a mass production basis, so at best, your vehicle has a middle-ground, compromise curve. At Performance Distributors we take all of your engine's specifications into consideration in order to provide you with the optimum advance curve. A super smooth curve will eliminate engine damaging detonation and give you the most efficient combustion possible. Light throttle ping is eliminated by the use of our special vacuum advances, factory calibrated just for your application. An adjustable vacuum advance will not be needed!

Our D.U.I.'s are superior to point type units because they are virtually maintenance free, can handle more voltage and last much longer. They are also better and more practical than magnetos. Our D.U.I. distributors send twice as much fire into the combustion chambers than a magneto because they allow twice as big a plug gap to be run. Spark plugs stay cleaner longer. This is a true "blueprinted" ignition system using only brand new parts. All of the moving parts in the advance system are hand-fitted to assure the smoothest advance curve possible. The distributor caps are offered in blue, red, yellow, clear or black and have solid brass terminals and contain the D.U.I. coil. The Dyna-Module, which has more electronic dwell in it over a stock module, is also included. Most roller cam applications require a bronze gear which is additional. This unit can be used with most street blowers with room to spare.
