Detailed Description

FCS 84575 is a rear glass lift support for vehicles with liftgate or rear glass access that relies on gas-charged support movement. The specified compressed length, extended length, and stroke length help match the opening arc and holding position required by the rear glass on the listed models. This part number 84575 is a practical choice for restoring rear glass operation on a Chevrolet Trailblazer EXT, GMC Envoy XL, Isuzu Ascender, GMC Envoy XUV, or Saturn Relay.

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

Common Problems It Can Solve

  • Rear glass that will not stay open
  • Weak or slow lift support movement
  • Rear glass dropping unexpectedly
  • Uneven or inconsistent opening effort
  • Loss of support for hatch glass access

Installation Notes and Tips

Verify the compressed length, extended length, and stroke length against the original support before installation. Confirm the vehicle application by year, make, and model, and compare the mounting points and rear glass configuration on the existing part. For best results, replace worn supports when rear glass hold-open force has noticeably declined.

Quality Assurance

FCS replacement components are cataloged for direct-fit body and glass service applications. Part number 84575 is listed for the specified vehicle fitments and dimensional requirements.
