When you are consuming more power than your stator can make you need to add another source for power. The stock ECU will pull power out of your RZR if you do not have enough voltage, therefore by adding the alternator kit, your RZR will gain power. The stock accessory relay will drop out at 12.5 volts.
90 amp Alternator - This alternator puts out 50 amps at idle. Our 90 amp alternator is the same type of alternator as you would find on any vehicle on the road and any stock SXS that comes factory with an alternator.
180 amp Alternator - This Brand X Electrical alternator is a marine-style alternator. With sealed brush holders, you will not have to worry about getting your unit soaked in mud or water. We have seen 110 amps at idle so far, we will put a bigger load on it soon and see how much we can get out of it.
Warranty: This alternator comes with a lifetime warranty at parts cost for repair and/or rebuild. Contact Brand X Electrical directly for all warranties. There is no limitations on their warranty, they do not care if you wired it backwards or dropped it down a flight of stairs, you're still covered. No questions asked!
LaRue Performance’s Polaris RZR alternator kit is an excellent addition to your stock OEM stator and here is why. The stock stator alone simply cannot keep up with multiple electrical components, including (power steering, ignition, communications, lights, navigation, and pumpers) or anything else you may power in your RZR. Whether you are on top of a big hill, sitting back enjoying your accessories, or racing through the desert, this alternator kit will keep your maximum power from any losses. This powerful alternator will take you safely out of those low-voltage limp modes, and on track to keep running at maximum power.
Here at LaRue we have personally dyno-tuned and researched many RZRs on our dyno machine. Throughout the course of this development, we have seen the power drops and the low voltage limp modes along with the results they have displayed. What happens when the OEM stator starts to heat up along with the other components like the ignition it becomes clear that the stock stator loses power. When the component is running and rising in temperature, more power is required and that simply does not exist within the stock stator.
Through this experience, we thought long and hard about what we could do to change these results and keep full voltage & power to the RZR. Our solution was to innovate and come up with our own Billet RZR alternator kit that also charges during idle. We’ve run and tested our kits from Oldsmobile Hill too long rides from the shop in Scottsdale to the Verde River. Durable, reliable, and great looking are only a few of the features this kit has to keep you going at the maximum power you need and expect from LaRue Performance!
