Added durability makes the Fleetline 85000 series the standard heavy duty product for today's low friction suspension. Designed as a direct replacement for the original equipment shock, FleetLine shock absorbers by Gabriel provide a valving rate that compensates for initial truck suspension softening, providing performance that better matches the original ride. Built with original equipment quality components and 10 stage valving to ensure superior performance throughout the life of the shock, it also reduces wear and tear on other costly suspension and vehicle parts. And like all Gabriel shocks and struts, Fleetline shocks feature a chrome piston rod for superior corrosion resistance and a leak-proof piston seal which extends product life.
