These Brand New hi-performance Alternators can supply enough juice to power nearly anything your electrical system demands. One of their biggest advantages is that they provide almost full output at idle, where most rebuilt brands produce only 20-30% of their full capacity. The new units stay cooler, and last longer while being able to do so under much harsher conditions. The One Wire units only need one wire, and self excite themselves the minute they are spun by the engine. The internal regulators mean only one wire is needed between the alternator and the battery. No other wires are needed, which really simplifies and cleans up the engine compartment.

These Super hi-output Alternators are backed with an extended warranty, as well as a proof of performance tag, after each and every alternator is thoroughly tested before leaving the building. The ultra-high output at idle allows for quick charging of a low battery and while jump starting, without having to even rev the engine at all! Excellent for winching, on board welders, camping, snow plowing and firing up big engines. We haven't found a better alternator yet. If we do, you'll be the first to know! But this is it!!!
