This support uses Stabilus Lift-O-Mat technology. Hydraulic damping works with an oil channeling system and the patented labyrinth piston for controlled, steady motion. Stabilus tunes the oil viscosity and piston configuration for each application. A proprietary seal-guide system is also part of the design.
A lift support may need replacing if the liftgate won't stay open, drifts down on its own, or feels heavier than usual to raise. For best results, Stabilus recommends replacing lift supports in pairs.
