Detailed Description

This Stabilus lift support is engineered for the rear hatch on GMC Acadia models with a power liftgate. The 3B-181910 uses OE-style dimensions and attachment points to support smooth hatch movement and consistent hold-open performance. It cross-references AP Exhaust 645800 for the same application.

Compatible With: Fits 2007-2015 GMC Acadia, Hatch Lift Support - Power Liftgate; Fits 2016 GMC Acadia, w/ Power Liftgate; Fits 2017 GMC Acadia Limited, N/A. The fitment coverage makes this a practical replacement for GMC Acadia rear liftgate support service when the original strut loses pressure or no longer holds the hatch properly.

What It Helps Fix

• Rear hatch that drops too quickly
• Liftgate that will not stay open
• Weak or uneven hatch support
• Hard-to-lift rear cargo access door
• Noise or binding from a worn gas strut

Installation Notes and Tips

Verify the existing strut length, end fittings, and mounting style before installation. This unit uses plastic socket connections at both ends, so the vehicle must match that attachment style. Replace worn supports in pairs only when the vehicle service procedure calls for it, and support the hatch securely during removal and installation.

Quality Assurance

Stabilus is a recognized OE supplier of gas springs and lift supports, and this part is built to meet the dimensional and force requirements of the listed GMC Acadia applications. Part number 3B-181910 is specified for direct replacement use on the confirmed fitment vehicles.
