FleetLine Heavy Duty Cab Shock Absorber
Your truck cab is your office, and the Gabriel Suspension Shock Absorber helps keep it steady over long hours on the road. This FleetLine heavy-duty cab shock controls movement between the chassis and cab, limiting the constant motion that stresses mounts and onboard electronics. A super-finished chromed piston rod is used to promote smooth shaft travel and consistent sealing, even in dusty or abrasive road environments. As vertical motion is controlled more effectively, sharp impacts and continuous vibration are reduced inside the cab. The Gabriel 83911 shock is specified for heavy-duty cab suspension layouts where controlled damping is required rather than ride height support.
