A new high amp alternator on your vehicle can make a huge difference of the charge level of your battery, and will also keep full power going to your ignition and accessories. Having a full supply of current to the ignition is very important for performance.

A volt meter will not indicate a weak low amperage alternator, only voltage output. If you have electric fans, cdi ignition, electric fuel pump and/or an amplified sound system, this is a must.

The best stock 10si GM alternator ever made from the factory only had a max output of 63 amps and low as 37 amps, with the exception of the GM high output 15SI model, and it used an oversize case. Its output was right at 80 and 100 amps depending on options. These options required higher output alts to maintain proper current to them, and keep the battery at full charge. Our high capacity model will keep up with most any current demand placed upon it. Units of lesser output or quality may fall behind on supplying proper current, and this can cause an array of problems.

MOST CUSTOM SHOW CAR OWNERS WILL CHOOSE THIS TYPE ALT. MANY STREET RODS CHOOSE THIS FOR THE ONE WIRE SIMPLICITY. LESS WIRING. IT'S IMPOSSIBLE TO HOOK UP WRONG. ONE WIRE TO THE BATTERY, AND THAT'S IT.

The quality of this alternator is excellent. This is the model that I run on my race car. It works double duty, keeping charged two Hawker Odyssey batteries, 625 cca each. I run a twin 11 inch high powered fan setup, cdi ignition, electric water pump, head and tail lights, high volume electric fuel pump, and more. This alternator is a must, as much of my time is spent sitting in the staging line with the engine idling, and I have a reduction pulley on the crank. My race car is a pro-street legal car that I drive on the street. Never has it failed to keep the batteries fully charged. The volt meter stays in the 13+ zone at idle with everything running. For those that set the engine idle speed very low, the voltage may drop below 13, but soon as the rpm is increased, the voltage will rise quickly.

GM 10SI Alternator

This is the traditional 10SI series GM alternator. These alternators have proven to be one of the most reliable products we sell. There are many different companies that sell a similar unit, and rest assured, most are not to be compared to ours.

This alternator may be used on OE GM applications that use a three-wire hook-up or as a one-wire hook-up for applications that do not use the conventional hook-up. The 10SI internal regulator alt came into use around 1973. It was the first year for the internal voltage regulator.

The chrome finish on this alternator is much better than some of the others we have seen on the market, but it is not flawless, as some people seem to expect it to be.

The reliability of this alternator is outstanding. The failure rate is nearly nonexistent. We can't think of any electrical product that we have ever sold having a lower return rate. Rest assured many other units such as this on the market are not of this quality.

Our goal is to remain the lowest cost, best value, best service company in the industry. We are fully aware of other lower cost alternators on the market, and we know for a fact our unit is far superior in function and build quality than most if not all others on the market.

The polished alts on the market do not look good at all. The cast aluminum case does not polish out well, not to mention polished units will oxidize quickly. This could be due to the type aluminum used, but they just don't look good. The chrome over aluminum has a very rich tone to it, unlike chrome over steel. If you buy a polished or plain cast aluminum unit, you will most likely be very disappointed. The chrome over aluminum model we have will always clean up like new regardless of age or use.

Customers have asked us if this unit new, remanufactured, or rebuilt. These units are 100 % BRAND NEW.

This unit will fit any applications that used the 10SI alternator, as well as the external regulator alt systems that were in use prior to the internal alt era. Get rid of the external regulator and all the messy wiring, not to mention those alts were very low output. This unit has a self contained regulator built into it, and the one wire voltage excitation module for one wire hookup.
