Fleet operators understand the value of a high-quality shock absorber. They also understand that no two roads are the same and no two payloads are the same. That's why we offer our Gabriel GasSLX shocks for trucks, trailers or buses. Featuring three adjustable settings: Regular, Firm (closest to OE ride performance), and Extra Firm, the GasSLX is a premium adjustable gas shock that provides customizable comfort and control, while delivering the ultimate in performance and durability. Adapting to diverse road conditions and payload capacities, the GasSLX's gas cell design creates a physical barrier between gas and the high-temperature fluid, which prevents aeration – a major cause of fade or reduced damping. Fade reducing gas cell technology is a full-life feature, best suited for longer life commercial vehicle applications. Custom-blended, high-temperature fluid reduces friction and wear in extreme operating conditions. In addition, a multi-lip viton rod seal is incorporated for greater fluid retention and high-temperature performance.
