Replacement REPB612902 Rear Window Glass Lift Support OEM# 51248402405

The Replacement REPB612902 is a direct-fit rear window glass lift support designed as an OEM-equivalent replacement for the BMW X5 (E53) 2000–2006. This gas-charged strut supports the upper hatch rear window glass, holding it securely open while you access the cargo area. Over time, the original gas spring seals wear and the unit loses pressure, causing the rear window to drop unexpectedly — this replacement restores that function to factory performance.

Key Features:

• Direct OEM replacement for BMW part number 51248402405 (also known as a lift cylinder or hatch gas strut)
• Gas-charged design uses compressed gas in a sealed cylinder to support the weight of the rear window glass
• Extended length: 20.83 in | Compressed length: 14 in | Force: 119 lbs
• Corrosion-resistant rod finish for long service life
• Leak-proof piston seal maintains consistent lift force
• Direct bolt-on installation — no special tools required
• Sold individually

OEM & Cross-Reference Part Numbers: 51248402405, SG302006, 6616, 4B1036VW, 612075

Restoring a properly functioning rear window lift support ensures safe, hands-free operation of the upper hatch. Replace worn or failed struts in pairs for balanced performance and even wear.
