Keep the rear hatch on your 2010-2015 GMC Terrain rising smoothly and holding safely open with the Stabilus Liftgate Lift Support 3B-406305. This gas-charged Lift-O-Mat mounts on the right side and uses a temperature-compensating piston, part of the Stabilus OE system engineered to keep lid and gate operation consistent across a wide temperature range.
Signs a lift support may need replacing include a gate that drifts down, feels weak, or won't hold itself open. Easy to install and requires no special tools.

This part cross-references / interchanges with the following part numbers:
What vehicle does this lift support fit?
It is a direct-fit replacement for the 2010-2015 GMC Terrain. Check the "Vehicles it fits" section to confirm it matches your vehicle.
Which side does the 3B-406305 mount on?
This support is cataloged for the right side. Because of how it operates, it must be mated with a separate support on the opposite side.
Do I need to replace both supports at once?
It's recommended. For best results Stabilus advises replacing them in pairs so both sides provide balanced hold-open force and controlled motion.
What does the temperature-compensating piston do?
Below 0°C it increases hold-open force to help keep the gate open; above 0°C it reduces closing effort, with rated performance from -30 to +80°C.
How do I know when a lift support has failed?
Signs include a liftgate that slowly drifts down, feels weak when raised, or won't stay open. If a worn support is the cause, this replaces it.
