The all-new, all-electric 2025 Bollinger B4 is the ideal canvas to build the perfect work truck for your business’s needs. Whether it’s an electric box truck, a refrigerator truck, a stake body, a contractor body, or something else, the B4 will be the most important battery-powered tool.  

The B4 is an upfitter’s dream. It’s designed with completely flat frame rails that securely house its twin 79 KWH battery packs and other components in between to remove obstacles that can make upfitting an EV truck a challenge. At Bollinger Motors, we have a list of “Preferred Upfitters” with expert knowledge, skills, and the proper equipment to upfit our electric truck to fit your business. To help ensure your experience goes smoothly, we highly recommend working with a Bollinger Preferred Upfitter. If you don’t see your desired upfitter on the list, encourage them to contact upfitter@bollingermotors.com to get the program documentation and join the team.
