One of the most common questions we get asked is "how large (amps) of an alternator do I need?" All stock vehicles will typically get by with small alternators in the range of 60 to 100 amps. As our industry has evolved over the years, very few vehicles can still be considered "stock". We have come a long way from needing to run a few lights and a radio. Air suspension, sound systems, air conditioning, electric fans, aftermarket ignitions and electric water pumps are just handful of the upgrades common in today's builds.
Here at CVF Racing we provide a wide variety of alternator sizes that allow you to accommodate just what you are running in your vehicle. In fact, all of our Wraptor™ All Inclusive Serpentine Systems include a 140 AMP alternator by default to help you run whatever you need. Luckily if 140 AMPs isn't enough, we have an upgrade available for a 300 AMP alternator by Mechman available with all CVF Wraptors.
