This Stabilus gas spring is engineered to match the dimensions and mounting style needed for the rear lift support application on the GMC Terrain. The 10 mm rod diameter, 22 mm tube diameter, and plastic socket ends help ensure proper alignment and consistent lift assistance.

- Original gas strut has lost pressure over time
- Noise or binding during liftgate movement
Installation Notes
Verify the existing support length, end fittings, and force rating before installation. This part uses plastic socket connections, so confirm the mounting points on the vehicle match the original design. For best results, replace supports in matched condition when the opposite side shows similar wear, and support the liftgate securely during service.
