Hunter Engineering Co. said its new GST9600HD ForceMatch wheel balancer offers vibration management and wheel uniformity for a wide range of passenger cars to heavy-duty trucks. The balancer uses loaded roller contact to measure runout of a tire/rim assembly and minimizes wheel-related vibration with pinpoint accuracy. The GSP9600HD can balance wheels from 10 inches to 30 inches in diameter and assembly weights up to 500 lbs., Hunter said.
