Detailed Description

This Tuff Support back glass lift support is intended for rear glass lift applications on GM midsize SUVs with liftgate glass access. It serves as a direct replacement option for vehicles that need controlled opening and holding support at the back glass, including Chevrolet Trailblazer, GMC Envoy, Buick Rainier, Isuzu Ascender, and Oldsmobile Bravada models within the listed years.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

  • Back glass that will not stay open
  • Weak or failing rear glass support force
  • Glass that drops too quickly when opened
  • Uneven or inconsistent lift support operation
  • Rear hatch glass that is difficult to hold in position

Installation Notes and Tips

Verify the vehicle year, make, and model before ordering. Match the existing lift support length and mounting style to the original rear glass support on the vehicle. For best results, inspect the mounting points and surrounding hardware for wear before installation.
