Gabriel 89459 Details

Gabriel FleetLine GasSLX heavy duty shock absorbers feature three adjustable settings: Regular, Firm (closest to OE ride performance), and Extra Firm, to provide 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 fluid, which prevents aeration, a major cause of fade or reduced damping.

Gabriel GasSLX Features

  • Unique Gas Cell design reduces fade and increases ride comfort
  • Larger 1-5/8 inch bore design provides performance and durability you can count on
  • Super-finished chromed piston rod to inhibit corrosion, ensure proper seal, and provide a more consistent wear surface
  • 360° arc-welded end mounts provide superior structural strength
  • Specially formulated high-temperature fluid reduces friction and wear in extreme operating conditions
  • Multi-lip Viton Seal: a more robust design for greater fluid retention and high-temperature performance
  • Hydraulic Rebound Stop creates a hydraulic cushion preventing impact damage (where required by design)
