Oval track TMS 5500SL Davis Technologies Traction Control device with hand held programmer. Purchased in March for $6500. Used during a test for 2 days, found system was not beneficial for the current motor package being used. (Believe it would be beneficial in 400+ HP applications) Still in original box with all documentation. Like new. Will ship to Davis Technologies for quality assurance and can ship direct to buyer from there. Will only respond to serious offers and inquiries.
