The Gabriel FleetLine 85000 Series shocks are specifically designed for Class 6-8 trucks, buses, and trailers. The shocks feature a larger bore size, increased fluid capacity, and consistent damping to provide the long standing quality and durability customers expect from Gabriel Heavy Duty products. With billions of miles of real-world use and testing in extreme conditions, the entire family of FleetLine shocks have been the proven choice for decades, says the company.
