mousetrap cars and vehicles

100% More Torque and 100% More Power
Designed by our master car builder Bartley Jones, The Jones Pulley system give a mousetrap racer as much as 100% more power... and... keep that power pulling up to 50% longer than all other vehicles! The Jones Pulley system is designed to maximize the winding of the mousetrap's spring more then the traditional 180 degrees. The Jones Pulley system will give your racer an almost unfair advantage as the explosive acceleration of this vehicle causes it to pop a wheelie as it "rockets" off the start line.  The Jones Pulley System is designed for all speed-trap contest and king of the hill climbing challenges.





For those who want to set a new record
Pulleys come pre-drilled for an optional 6" lever arm that is included in the kit, this is for changing the amount of torque. Also comes complete with instruction guide for building the Jones Pulley System.

Includes the following: 1- Jones Pulley, 2 - cage sides, 1 - pulley axle, 1 - optional 6" lever arm, 1 - instruction sheet.

Important Notice: The Jones system requires the alteration of the mousetrap and the mousetrap's spring causing it to wind more than 180 degrees. Not legal for all contest.
