Road Force® GSP9700 Balancers Earn Exclusive GM Approval

Hunter's New OCL430HD Rotor Lathe Brings Innovative Lathe Technology to Heavy-Duty Brake Service General Motors Company has named Hunter Engineering Company's Road Force® GSP9700 Balancer the only approved balancer for GM dealerships.

High customer satisfaction scores require a smooth driving feel on all road surfaces. Tire-related shaking and vibration problems can be difficult and time consuming to diagnose and correct. These disturbances are caused by three distinct variables: imbalance, out-of-round conditions, and tire force variation. Hunter Engineering's patented Road Force GSP9700 Balancer is the only wheel balancer in the industry that can identify and solve these shaking and vibration problems.

Hunter's Road Force GSP9700 Balancer simulates how the wheel actually performs on the vehicle by applying up to 1,250 lbs. of force over the entire tire/rim assembly. With its patented sensors, Hunter's balancer pinpoints the lowest point of a rim (for runout) and the stiff area of a tire's sidewall under load (for radial force variation). Then the patented software automatically determines how the assembly can be match-mounted to offer the best ride quality.

Recent GM tests compared Hunter's accuracy and repeatability to a laboratory-grade, $500,000 Tire/wheel Uniformity Grader (TUG). The nearly identical results were both "amazing" and a "real eye-opener" for GM. GM is encouraging its dealers to own Hunter's Road Force GSP9700 Balancer at a small fraction of the cost.

Several GM Technical Service Bulletins (TSBs) reference the Hunter Road Force GSP9700 Balancer. In addition, GM Engineering utilizes the Road Force GSP9700 Balancer to verify all tire/wheel assemblies returned for warranty claims. In a recent memo to its dealers, GM recognizes the Road Force GSP9700 Balancer as an excellent tool for its dealer network and takes this opportunity to give its strongest endorsement.

GM has also given exclusive approval to Hunter's Direct-Fit Collets. When used with the Road Force GSP9700 Balancer, the Direct-Fit Collet design improves measurement consistency. The shorter, low-taper design fits precisely in the hub bore only, promoting accurate center-mounting and distortion-free clamping, while protecting against damage to certain designs like chrome-clad wheels.
