7.100 Kit Vehicles

A kit vehicle is a vehicle that is built for private use, not for resale, and is not constructed by a licensed manufacturer or remanufacturer.

  • Kit vehicles are often replicas of well-known and expensive classics but can also be commercial vehicles and trailers.
  • A kit vehicle is registered by the kit manufacturer’s VIN (they are exempt from the federal 17-digit VIN requirement) and does not have a model year. The make abbreviation is the kit make followed by the abbreviation KT.
  • All kit motor vehicles and kit trailers weighing 6,001 pounds or more unladen, y vehicles having more than one VIN must be referred to the California Highway Patrol (CHP) for a VIN verification or assignment.
  • A “CAL” number is assigned by DMV to trailers with an unladen weight of 6,000 pounds or less, unless the original unaltered VIN remains on the frame.

Commercial Vehicles Assembled from Kits (VC §580)

Manufacturers of large commercial vehicles sell kits which can be made into complete vehicles.

  • These kits usually consist of a frame, steering gear, cab (complete with wiring and instruments), radiator, hood, front fenders, and in most cases, the front axle and wheels.
  • The installation of an engine, transmission, rear axles, wheel, and tires makes the kit a complete vehicle.
  • The installed components may have been purchased separately in new or used condition or removed from a vehicle which is no longer serviceable.
  • Installation into the kit may have been done at an assembly plant, a truck repair shop, or by an individual.
