Going far beyond the traditional functions of a wheel balancer...

The Road Force® GSP9700 measures radial and lateral tire forces and provides instructions for solving ride and handling problems such as tire pull and wheel vibration that balancers and wheel aligners cannot fix.

Hunter's Road Force® GSP9700 is endorsed and recommended by vehicle manufacturers and proven by thousands of repair facilities worldwide as the industry standar

Faster Troubleshooting & Repair
Quickly calculates the contributions of the rim and tire to radial vibration problems and presents the technician with easy step-by-step repair instructions.

Identifies Potential Vehicle Pull or Drift Problems
The optional StraightTrak® LFM* feature measures lateral tire force, then applies that information to the set of tires, providing multiple placement choices to eliminate or minimize tire pull problems – an otherwise unfixable vehicle complaint during alignment service.

Dramatically Improves Ride Quality & Customer Satisfaction
Duplicates wheel vibration measurement and tire/wheel matching methods previously used only by vehicle manufacturers to provide that “new car ride.”

Increases Wheel Service Income
Establishes your shop as the wheel vibration and handling control experts. Reduces comebacks and enables you to service vehicles that other shops turn away.

The exclusive Road Force Measurement® system applies up to 1,400 pounds (635 kg) against the tire. The loaded roller detects non-balance, radial-force-related vibrations caused by eccentricity and constructional variation of the tire and wheel. Unlike non-contact measurement, the roller samples the entire footprint of the tire including the sidewall’s contribution to ride quality.

The Road Force® GSP9700 measures lateral and radial rim runout without removing the tire from the rim and quickly indicates if runout is tire-related. Runout can also be measured at the actual bead seat on a bare rim.

The Road Force® GSP9700 slowly rotates the wheel automatically during measurement.* The Road Force® GSP9700 then calculates the contributions of the tire and the rim to the vibration problem and presents the technician with easy-to-follow repair instructions.

Hunter's patented ForceMatch® feature cancels the stiffest point of tire radial force variation with the low spot on the rim. This helps eliminate vibration by minimizing the effects of radial force variation and rim runout.

QuickMatch® measurement may also be chosen to quickly audit and match-mount with loaded runout instead of force calculations if greater time savings during cycle time is preferred.

Once the correction is completed, the technician can continue with a precision wheel balance by instantly choosing the balancing method without key closure steps.

Offering the same service as vehicle manufacturers, the GSP9700 matches the stiffest area or high spot on the tire with the lowest spot on the rim to cancel vibration caused by radial force variation and provide the smoothest possible ride.

SmartSpoke™ Weight Locator Feature**
Derived from SmartWeight® balancing, the SmartSpoke™ weight locator feature exclusively enables the technician to achieve the best possible balance by placing only a single adhesive weight behind one wheel spoke instead of two weights behind two spokes. This feature reduces weight use, minimizes labor time and speeds the balance procedure.
