1. New Low profile button
2. New Auxiliary tachometer lead (Please read for additional information)
3. New flat braided ground 
4. New lower voltage starting capabilities
5. New matched high-performance, stock-appearing REV-N-NATOR coil. A must for optimal performance! 

* With this new generation REV-N-NATOR, we highly recommend using our matched coil!

* Our matched coil will get the absolute best performance, power and run ability out of your REV-N-NATOR I.C.U.

* Our coil is a performance-matched coil for the REV-N-NATOR. It outperforms all other leading performance ignition coils.

*And now, to add to your REV-N-NATOR complete package, for the best performance and run ability, The R/T Garage carries the highly recommended distributor made by FireCore. A perfect match to your REV-N-NATOR ICU and REV-N-NATOR coil! The REV-N-NATOR distributor by FireCore has 3 sets of advance springs and is very easy to adjust the mechanical curve. The REV-N-NATOR ICU, because it is a very high tech piece and is performing many different functions, needs a distributor with a strong signal (unlike the stock Mopar distributor, which has a weak signal), and the FireCore provides exactly what the REV-N-NATOR needs!

The REV-N-NATOR ignition system was manufactured for PURE STOCK as well as performance and race applications. The REV-N-NATOR does not hurt your original date coded plug wires.

Same great product, Made in USA!


The REV-N-NATOR is a true plug and bolt-in factory-appearing I.C.M. (aka Brain Box) that has been completely re-engineered with digital technology. It exceeds all stock Mopar boxes and includes a simple-to-use, built-in rev limiter.

The rev limiter has 7 different rpm limits, from 3,000 rpm test to 7,500 rpm. It can easily be changed by the touch of a button with easy-to-see LED lights. The LEDs also function as a digital tachometer.

REV-N-NATOR users will have huge HP increases over all factory stock boxes-Orange and Chrome, etc. On all dyno challenges, we also average more HP and torque than any other leading aftermarket high performance ignition systems.

Protect your motor from over revving, and for the purist, the REV-N-NATOR is the perfect bolt-in piece for your #'s matching motor. No extra wires or bulky boxes (all in one). With powder-coated color options of black or orange, the REV-N-NATOR bolts into stock locations with original wiring. All new digital, modern electronics in a stock-appearing box!

So, next time you miss a shift showing off to your buddies, you'll be confident, knowing you have The REV-N-NATOR—an OEM box and rev limiter. Good looks and state-of-the-art technology all in one!


*10-40 HP gains over all stock Chrysler boxes vary depending on engine application. For more information, visit our FAQ.

Testing the REV-N-NATOR

We have done years of extensive testing and development in many different settings, dyno environments and engines applications. On the dyno challenges, we have EXCEEDED THE LEADING PERFORMANCE IGNITION systems in HP and TORQUE. We originally set out to build a quality replacement for the factory Chrysler boxes, but keeping this a true "Plug n' Play" unit, with a rev limiter built in and a stock look has always been the first priority.Using our complete package, we can guarantee the best performance , run ability and quality of any other system on the market today!
