Stabilus 4B-524650 Back Glass Lift Support

Back Glass Lift Support for Jeep Wrangler

This Stabilus back glass lift support is built for controlled rear glass movement on Jeep Wrangler models from 2018-2025. It uses gas-charged force with dynamic damping to deliver a smooth, measured lift and a gentle closing stop for the rear glass.

• Maximum force: 160 lb
• Cylinder outside diameter: 0.709 in. (18 mm)

How the Lift-O-Mat Design Works

Stabilus uses a velocity-manifold groove inside the tube to regulate gas flow as the shaft extends. That controlled flow changes damping through the stroke, so the rear glass opens with consistent resistance and closes with a softer final stop. For Jeep Wrangler rear glass service, part number 4B-524650 is engineered for application-specific motion control and OE-style operation.

This part cross-references Tuff Support 612136 for the same application.

Common Problems This Part Can Address

• Rear glass that drops too quickly when opened
• Lift support that no longer holds the glass in the raised position
• Uneven or jerky rear glass movement
• Hard closing action at the end of the stroke
• Weak gas pressure from an aging lift support

Installation Notes

Verify ball socket end style and compressed/extended length before installation. Transfer any vehicle-specific mounting points as required by the application, and inspect the rear glass hinges and attachment points for wear before replacing the support. Confirm the part number 4B-524650 matches the Jeep Wrangler rear glass application before installation.

Quality Assurance

Stabilus is known for OE-focused gas spring engineering, and the Lift-O-Mat line is built around controlled damping for precise rear glass movement. Part number 4B-524650 is designed for consistent operation in the specified Jeep Wrangler fitment range.
