This nytro has a stage 1 supercharger on it and also has the motor work done to allow for a larger charger to be put on. It has timbersled front and rear suspension and a CR racing tunnel with U cooler and a 162 power claw track. Over all the sled runs great. I'm asking $10,000. The best way to reach me is at 530-913-1444 or 530-265-4639.
