12 Volt Conversion Kits for Classic Cars

Vintage Auto Garage started over 15 years ago, offering single voltage regulator/reducer to power original oil, gas, and temperature gauges when converting classic cars and trucks from 6 volt to 12 volts. Since then, Vintage Auto Garage has developed complete 6 volt to 12 volt conversion kits for almost every American classic make and model.

Our kits have been shipped to every continent in the world, used by every antique auto that was built with the original 6 volt positive or negative ground electrical systems. You can find all of our kits by year, make, and model below, and if for any reason you do not find one of the kits on our site, we likely still have the conversion parts available and are likely in the process of adding it to the site in the future.

If you have a project, large or small, that requires converting from 6 to 12 volts, and you cannot find your vehicle in our inventory, click on submit your project and one of our team members will send you a complete list of vintage auto parts for your specific classic auto.

Prior to 1955 most all American cars and trucks came with a 6 volt electrical system. 6 volts worked fine when these vehicles were new and the cars and trucks were driven daily to keep the battery charged. Today classic cars and trucks are not driven as often and the 6 volt batteries are never fully charged, therefore the engines may not start when hot or cold. All vehicle accessories today are made for 12 volt negative ground electrical systems, a vehicle with 6 volt system will not allow the use of any 12 volt device and it is difficult to get a jump start when the old 6 volt battery goes dead.

In most cases choosing 12 volt kits from Vintage Auto Garage will make the project go much quicker and simpler. All the parts needed for the make and model vehicle are in the kits plus a great set of instructions that will take the hobbest or professional mechanic step by step through the 12 volt conversion process.

In addition to the step by step instruction book, Vintage Auto Garage does offer phone support.

About Our 12 Volt Conversion Kits

Most vehicles, especially prior to 1955, came with 6 volt electrical systems. It wasn’t until after 1955 that most major auto manufacturers switched to the now more common 12 volt systems.

To their credit, the original 6 volt systems were very reliable, and in rare cases, there are some that still work even today. But now they’re over 65 years old, and in the process of repair and restoration of most classic American cars and trucks, it’s become time to switch to the more powerful 12 volt system.

Of course, you can’t simply plop a 12 volt into the vehicle and expect it to operate perfectly. That’s why we have created these 12 volt conversion kits, designed for essentially all American automakers. Our 12 volt electrical system kits come with everything you need to start the conversion process:

Ignition Coils
Alternator Charge Wires
Multi-gauge Reducers (Oil, Temp, Gas)
Hook Up Wires
12 Volt Alternators, and all reducers necessary to 12 volt conversions

Different vehicles may require different parts, but we make sure that our kits are equipped with every component for a fast and seamless transition. We also have walkthroughs available for free that can help take you step by step through the 12 volt conversion process.

Right now on our website, we have essentially all major makes and models:

But if for any reason you do not see your model vehicle here on our site, we are confident that we have all the parts you need to turn your 6 volt classic American auto into a 12 volt, no matter the make and model. Contact our team, and we’ll put together the parts you need and get it ready to order.

Our 12 volt conversion kits are our most popular products here at Vintage Auto Garage, and we encourage you to explore both the kits and the rest of our site to find any other products you need for your restoration and repair project.
