J.C. Whitney JRM63040009 Rear Liftgate Lift Support Right Side OEM Replacement 1647400445

The J.C. Whitney JRM63040009 is a right-side rear liftgate lift support designed as a direct OEM replacement for select Mercedes-Benz W164 ML-Class SUVs equipped with a power liftgate. This gas-charged strut restores proper liftgate operation, allowing the rear door to open smoothly and hold its position securely without manual assistance.

Key Features:

• Right-side (RH) fitment — designed specifically for the passenger-side liftgate strut position
• Power liftgate compatible — engineered for W164 models equipped with the powered liftgate system
• Gas-pressurized lift support provides consistent, controlled opening and closing force
• Leak-proof piston seal maintains pressure for reliable, long-lasting performance
• Corrosion-resistant rod finish for durability in all weather conditions
• Direct bolt-on installation — no special tools required
• OEM Reference Number: 1647400445 (also referenced as 164-740-04-45)

For best results and balanced liftgate performance, lift supports should be replaced in pairs. This part ships individually; order two for a complete replacement set.
