These extreme quality, high output, high performance heavy duty alternators both look great, work great and are extremely durable

The Reactor™ alternator is not just another stocker in a pretty package. The gleaming polished chrome plated or optional vintage natural aluminum housing of the Reactor™ 105 hides a super heavy duty power plant that makes a whopping 105 amps at fast idle (1), withstands ultra high RPM's, handles brutal current load demands and does it all while not requiring any external regulators or wiring other than one single wire going from this alternator to the battery. That's it! Compact, potent, powerful, durable and reliable all in one package. The Reactor™ Bolts right on for the specific applications available and works with virtually any existing electrical system or wiring! For more information on the Reactor™, read the detailed specs below...

!  Includes chrome fan cover plate on Polished and Chromed version as shown on the Reactor 105 version below, at no extra charge! Aside from it's good looks, the fan cover increases air flow as well as reduces fan flex at high RPM's. It can be easily removed for a more vintage, OEM appearance if desired.

the Reactor-75™ SPECS . . .
*   75 Amp output @ 1,475 rpm (2)
     (most alternators need 2,500-3,500 to achieve full their
          output, generating less than 1/4 at idle)
  (1)  =  fast idle based on 1,475 rpms    (2)  =  based on an 8" diameter crank pulley

the Reactor 105-HD™ FEATURES . . .
*   Super Heavy Duty for extreme conditions
*   Designed for high revving performance engines
*   Provides full output capacity even at idle (1)
*   Self regulated eliminates voltage regulators
*   Fully self contained - INTERNAL REGULATED
*   One wire hookup eliminates all other wiring
*   Just connect one 8ga. wire to the battery-that's it!
*   Shrouded high capacity low noise cooling fan
*   V-belt deep grooved racing pulley included
*   Polished gleaming Chrome plated finish
*   Mounts in stock location - No modifications
*   Direct replacement for Ford small case alternator
*   Hybrid Design Ford small style front half mated
     to GM style rear half - Super Smooth Show Look!

Most high performance engines and cams idle between 1300-1500 rpms, however the below chart shows output at lower rpm's...

Alternator Comparison

This very special alternator out performs and outlasts virtually anything in it's category on the market. The extra high output of the Reactor™ at fast idle (1) feeds all the electrical needs for electric fans, high output ignitions, engine management systems, radios, heaters and high output headlamps. Most other alternators only produce a fraction of their rated output at idle and have to be revved to create their maximum output, and many of the other so called high output 100 amp ones only put out 15-20 amps at idle, with barely put out their maximum current when revved to 2500-3000 rpm. This does little to help while in traffic, parades and especially cruising in high gear on the highway at a low RPM.

This under hood Power Plant solves all those problems and more. The Reactor-105™ self regulated alternator eliminates the need for an external voltage regulator, or any other external charging system wiring.

This compact onboard regulator is easily replaced using over the counter GM parts found at just about any parts store... just be sure to use 100 amp regulators.

Solve ongoing charging system problems in one mighty stroke by installing this unit. All you need is one single wire going to your battery. That's it! It's as easy as that, and you can discard all your existing wiring!

And also unlike most other so-called "one wire" alternators that actually need a second wire from the key switch to "excite" the windings to start the current production, the Reactor™ is completely self contained and self excites the charging system as soon as  the engine is started and the alternator reaches it's energizing rpm (3). The alternator then  remains energized until the engine is shut down. This ensures there is no voltage draw while the engine is off, draining the battery. The Reactor™ alternator has stood up to demanding environments such as sand, mud, water and even the 400+ amp loads of a 12,000 pound winch as well as ultra-hi rpm revving racing engines!
