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.
