Detailed Description

This Tuff Support back glass lift support is made for rear glass lift applications on the Chevrolet Trailblazer EXT, GMC Envoy XL, Isuzu Ascender with Body Code XL, and GMC Envoy XUV. Use 612343 when replacing a worn support that no longer holds the back glass in position or opens smoothly. The part number 612343 also helps confirm the correct application during lookup and service ordering.

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

What It Helps Fix

  • Back glass that drops instead of staying open
  • Weak or uneven lift support action
  • Rear glass that is difficult to raise or lower
  • Noise or instability at the rear glass opening
  • Loss of support from a worn gas strut assembly

Installation Notes and Tips

Verify the vehicle year, make, model, and rear glass application before ordering. Match the existing lift support length and mounting style to the original unit on the vehicle. For best results, replace a worn support when the rear glass no longer stays open securely.

Quality Assurance

Tuff Support is owned by ISC Industries, a lift support manufacturer based in Turkey with a focus on automotive lift support production.
