Detailed Description

The Stabilus 4B-674278 back glass lift support is built for precise rear glass control on the Ford Bronco. Its gas-charged design and dynamic damping profile regulate extension speed through a groove-shaped velocity manifold, helping the lift support slow the glass as it reaches the end of travel. That controlled motion is useful where consistent OE-style operation and a gentle stop are important. This part cross-references Monroe Shocks & Struts (e.g., 7477, 585356) for the same application.

With ball socket ends, nylon end materials, and application-specific tuning, this Stabilus lift support is a direct-fit solution for Bronco rear glass service. If you are replacing a worn or weak lift support on a 2021-2025 Ford Bronco, part number 4B-674278 is built to restore stable lift and controlled closing action.

What It Helps Fix

• Rear glass that drops too quickly
• Lift support that no longer holds the glass open
• Uneven or jerky back glass movement
• Excess effort needed to raise the rear glass
• Noise or poor damping during opening and closing

Installation Notes and Tips

Verify the compressed length, extended length, stroke length, and end type before installation. Match the ball socket mounting points to the vehicle brackets and confirm the support is oriented correctly for the rear glass. Because mounting hardware is not included, reuse or source the required attachment components as needed. After installation, cycle the back glass several times to confirm smooth travel and proper hold-open function on the Ford Bronco.
