Raise and hold your rear glass with smooth, controlled motion using the Stabilus Back Glass Lift Support 4B-674278. This gas-charged lift support with dynamic speed control drops in as a direct-fit replacement for the 2021-2025 Ford Bronco, with an extended length of 16.42 inches. If a worn support can no longer hold the back glass open or lets it drift, this Lift-O-Mat unit replaces it.

  • Dynamic damping speed control: creates a fluid opening motion with no bouncing or jerking, using a velocity-manifold groove pressed into the tube wall that lets gas flow around the piston and narrows toward the end of the stroke for a gentle, controlled stop.
  • Internal mechanical spring: compresses in the closed position to give an added boost during initial opening.
  • Corrosion-resistant coatings: part coatings tested to automotive standards for corrosion resistance.
  • Easy installation: based on the OE design to help ensure proper fit, form, and function, and requires no special tools.

For best results, replace in pairs.
