The Ranger DST30P Wheel Balancer is designed to accurately and efficiently calibrate wheel and tire configurations. Like the DST- 2420 wheel balancer, the DST30P handles wheels up to a 30” diameter. Features include inside and outside measuring, manual wheel offset distance setting, self-calibration function, auto start when the hood is lowered, wheel holding manual brake pedal, and truck cone/spacer ring adapter set. This balancer has a 64-tooth magnetic transducer encoder built into it for minimal yet incredibly precise wheel weight placements. The encoder features precision-cut square teeth to convert rotary position to a digital electronic signal, quickly achieving maximum profile and top-dead-center positioning.
