Gabriel GasSLX – Shocks Absorber | Gas-Charged Heavy-Duty Shocks for Commercial Vehicles Trucks & Buses (Heavy Duty & Commercial Vehicles)About GabrielGabriel’s legacy in automotive suspension innovation continues w/ the GasSLX series delivering advanced gas charged shock absorbers for heavy duty commercial vehicles. Designed for trucks Trailers and buses GasSLX shocks provide a smoother more controlled rideProduct DetailsGasSLX Shocks – Adjustable Commercial Truck and Trailer Shocks (89000 series) - The three position GasSLX adjustable shocks absorbers by Gabriel allow you to choose from one of three settings Firm Regular and Extra Firm to match different applications. The GasSLX shock incorporates a gas cell design creating a physical barrier between gas and fluid preventing aeration which can cause fade or reduction in damping force. This gas cell technology is a full life feature and is better suited for longer life commercial vehicle applications. And like all Gabriel shocks and struts GasSLX shocks feature a super-finished chrome piston rod for superior corrosion resistance and a leak-proof piston seal which extends product life. Advanced gas cell technology improves gas retention and provides more consistent high temperature operation. Unique pressurized piston seal design reduces force velocity variabilities and self-compensates for wear. Gas Cell design is superior to gas charged shocks; gas cell double seals gas from fluid for optimum performanceProduct FeaturesTop of the line adjustable heavy-duty gas shock for class 7 – 8 vehicles school buses and transit busesThree settings for adjustability: OE ride (firm) increased handling & control (extra firm) or maximum driver comfort (regular) Specially formulated high temp. fluid & multi-lip Viton rod seal reduces friction & wear even in extreme operating conditionsChromed piston rod to inhibit corrosion ensure proper seal lubrication and provide a more consistent wear surfaceInstallationProfessional installation is recommended to ensure optimal performance in heavy-duty vehicles.
