Hold your tailgate glass open with steady, controlled support using the Focus Auto Parts Back Glass Lift Support 84423. It drops in as a direct-fit replacement for the 1984-1990 Ford Bronco II, taking over from a worn original that can no longer hold the rear window up.
A back glass lift support extends between the body and the raised rear glass, holding it in the open position and helping cushion its travel as it opens and closes. When the original weakens, the glass may drift down on its own, feel heavy to raise, or fail to stay up — common signs this part may need replacing.
If a failed lift support is the cause of a rear glass that won't stay open, this unit replaces it. Diagnose the cause before ordering. Manufacturer part number 84423.
