The Gabriel FleetLine Heavy Duty Shock Absorber is a 1-5/8 inch bore unit designed to control the suspension movement of commercial trucks and trailers. This shock utilizes a specialized valving system that adjusts to varying road conditions, providing firm control for heavy loads and a smoother ride when the vehicle is empty. The reinforced mounting ends and cold-drawn cylinder tubes are built to withstand the intense heat and mechanical stress of long-haul operations. This robust dampening performance allows the Gabriel 85052 to extend the life of other suspension components by reducing the frequency of spring rebound.
