Product Description

FleetLine Heavy Duty Shock Absorber

Features & Benefits

• Solid steel eye rings provide a durable and stable mounting interface
• 360° arc-welded end mounts reinforce structural integrity under continuous suspension stress
• Piston seal geometry minimizes internal leakage during high-pressure cycles
• Design improves shock responsiveness during rapid load shifts

FleetLineTM Shocks – Commercial Truck and Trailer Shocks (85000 series) - 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 super-finished chrome piston rod for superior corrosion resistance and a leak-proof piston seal which extends product life. Unique pressurized piston seal design reduces force-velocity variabilities and self compensates for wear. Cold formed, 360 degree arc-welded eye-ring and mounts and a 1 5/8” bore provide improved durability. A hydraulic rebound stop, where required, prevents shocks from topping out and suspensions from overextending

Gabriel Suspension Shock Absorber 

The Gabriel Suspension Shock Absorber features a bulged body that increases fluid volume, allowing the shock to dissipate heat efficiently during long hauls. Its large 1 5/8-inch bore provides the hydraulic capacity needed to moderate chassis movement during aggressive load changes. The chromed piston rod ensures reliable seal contact and resists deterioration, and anti-corrosion end mounts preserve structural strength in various environmental conditions. A sturdy piston seal paired with fade-resistant oil helps maintain consistent damping performance even under punishing freight cycles. Designed for Kenworth and Peterbilt vehicles operating in harsh, high-load transport environments, the Gabriel 85989 delivers exceptional suspension control across a variety of road and load conditions.
