Shocks, air springs, and tires work together and wear together. That’s why replacing your fleet’s worn-out shocks aids in maximizing both air spring and tire life, as well as ensuring your fleets’ safety with proper vehicle control and handling. With the exclusive Gabriel HD Shock Absorber Tester, technicians can verify the useful life of their commercial vehicle’s shocks, including Gabriel’s Heavy Duty FleetLine Shocks, in three easy steps. The handheld digital tool also includes a QR code to guide users through the heat test.
