It is a direct-fit rear glass support for vehicles that use a back glass opening separate from the main liftgate, including Cadillac Escalade and Chevrolet Tahoe applications.

Common Uses

  • Restores rear glass lift support function when the glass no longer stays open
  • Addresses weak or slow-moving back glass on GM SUVs
  • Helps replace worn support hardware on rear glass liftgate assemblies
  • Supports smoother opening and closing of the back glass

Installation Notes

Verify year, make, and model before ordering. Match the rear glass application to your vehicle’s liftgate configuration, since this part is for back glass use rather than the main tailgate. Professional installation is recommended if the existing support is seized or the mounting points are difficult to access.

Quality Assurance

Tuff Support is owned by ISC Industries, Turkey’s premier lift support manufacturer, and part number 612631 is produced for rear glass liftgate applications requiring consistent support performance.
