This choice determines which base kit you receive and the cost of the kit. The Nations secondary alternator in this bundle ships with the correct mounting and other hardware/parts for your specific vehicle. Be sure to choose carefully! For Sprinter vans, we offer both the "3-belt" version of the kit (our preference) and also the kit for the factory, N62 bracket if your Sprinter has this factory secondary alternator bracket. The vehicles included in this list are our "standard" kits. We can customize a kit to your specific needs if you vehicle isn't listed here. Please contact us with any questions!
