Gabriel 89426 GasSLX Heavy-Duty Adjustable Shock Absorber – Truck, Trailer & Bus Suspension

Upgrade your heavy-duty suspension with the Gabriel 89426 GasSLX Shock Absorber, engineered to deliver dependable ride control, durability, and adjustable performance for demanding truck, trailer, and bus applications.

The GasSLX features three adjustable damping settings—Regular, Firm, and Extra Firm—allowing you to customize ride comfort and handling based on operating conditions and load requirements. Its Gas Cell design separates gas from fluid to help reduce aeration and minimize performance fade.

A 1-5/8-inch bore, chrome-plated piston rod, high-temperature fluid, and multi-lip Viton rod seal provide durability and consistent performance in demanding operating environments. The 89426 uses an S21 upper mount and ES36 lower mount and includes a dust tube.
