The Wrangler is an easy to build long distance traveler that illustrates one of the most basic design concepts for achieving extreme travel distances, lever arm length. A longer lever arm means that more string can be wound around and pulled from the drive axle translating into greater travel distance. The Wrangler is built on our top selling Basic Kit chassis. The Wrangler comes ready-to-assemble with pre-cut and pre-drilled parts so you can be ready for action and racing on the same day. As with all our kits, The Wrangler comes with step-by-step instructions that are filled with tons of top secret performance tips and tricks that have been developed exclusively by Doc Fizzix so that you will have all the information you need to make The Wrangler a winner.

Why Doc Fizzix:

At Doc Fizzix, we have been designing, making, and building mousetrap powered cars for more than 30 years. Unlike any other mousetrap vehicle kit you will find on the market today, each of our kits has been designed and tested over and over again to insure your success. We use only the best quality parts and components in our kits. We have been featured multiple times in books, magazines, and national aired programs. We wrote the very first book devoted exclusively to the building of mousetrap vehicle selling more than 200,000 copied world wide. Our kits are used in more schools across the country than any other brand. Mousetrap powered cars and vehicles is our specialty.


  • Light-weight balsa wood
  • Brass tubing axles
  • 15-inch lever arm
  • Pre-cut and pre-drilled
  • Low inertia DVD layer wheels
  • Doc Fizzix's easy-wind, snag-free propulsion system
The Wrangler can be assembled in less than 30 minutes for most first time builders and when finished it will travel from 40-55 meters. But the single best upgrade is the 15-inch long lever arm that pulls almost one meter of string pulled from the drive axle. The total pulling distance for The Wrangler is about 30 meter before the vehicle begins coasting; that is over 250% more pulling distance compared to other mousetrap vehicles.

As with all our top mousetrap racer kits, The Wrangler includes our "easy-to-wind" and "snag-free " string release system that will not tangle or snag for increased performance, a technique developed exclusively by Doc Fizzix.
