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! NOTE: if your Sprinter van came with the factory N62 alternator bracket, this kit is NOT compatible. There is an a Nations product for the N62 bracket but it's not recommended by ourselves or by Nations Alternator. For Sprinter vans, we always supply the "3-belt" version of the kit. 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!
