Genuine Mercedes 166-980-37-64 Left Power Liftgate Lift Cylinder

The Genuine Mercedes-Benz 166-980-37-64 is a factory OEM power liftgate lift cylinder designed for 2013-2019 GL-Class and GLS-Class SUVs equipped with power-operated tailgates. This pneumatic spring provides the hydraulic support needed to smoothly raise and hold the rear liftgate in the open position, working in conjunction with the vehicle's power tailgate system.

Key Features:

• Genuine Mercedes-Benz OEM part for precise fitment and reliability
• Left side position pneumatic lift cylinder
• Engineered specifically for power liftgate systems
• High-strength leak-proof piston seal for consistent performance
• Corrosion-resistant rod finish for long service life
• Replaces part number 166-980-22-64

This lift cylinder is a critical component of the power tailgate system, providing the necessary force to assist with lifting and supporting the weight of the rear liftgate door. When functioning properly, it allows for smooth, controlled operation of the automatic tailgate opening and closing functions. Over time, these hydraulic cylinders can lose pressure or develop leaks, resulting in a tailgate that won't stay open, closes slowly, or fails to lift properly. Replacing worn lift cylinders restores full functionality to your power liftgate system.

Important Notes:

• This is the left side unit only; right side sold separately
• For vehicles equipped with automatic rear hatch (power liftgate)
• Professional installation recommended for proper calibration
• Comes with minimum 12-month manufacturer warranty
