• Stabilus LIFT-O-MAT® back glass lift support replaces the worn OE unit to restore proper back glass operation. A patented Labyrinth Piston manages extension speed for smooth motion and a controlled stop. This damping profile helps prevent unsightly bouncing and shuddering of the back glass as it opens. A protective dust cap helps control dirt and grit buildup at the rod and tube union, reducing the chance of contaminants being cycled into the part. High-precision sealing and corrosion-resistant materials help maintain consistent performance across thousands of operating cycles. The fully sealed design requires no lubrication, adjustment, or routine maintenance over its service life. Engineered to OE specification for exact fit, form, and function wit
