Detailed Description

This Tuff Support back glass lift support is made for vehicles that use a rear glass support to hold the liftglass in the open position and assist smooth movement during opening and closing. If you need a replacement lift support for a 2015-2020 Cadillac Escalade, 2015-2020 Chevrolet Tahoe, or 2015-2020 GMC Yukon, part number 612623 matches the listed applications and supports rear glass service on those vehicles.

What It Helps Fix

• Rear glass that will not stay open
• Liftglass that drops unexpectedly
• Weak or worn support pressure at the back glass
• Slow or uneven rear glass movement
• Noise or binding from an aging lift support

Installation Notes and Tips

Verify the vehicle year, make, and model against the listed fitment before ordering. Confirm that the existing support matches the back glass application and compare the original part length and end fittings before installation. For best results, replace a worn support when the rear glass no longer holds position or requires extra effort to open.

Quality Assurance

Tuff Support is backed by ISC Industries, a manufacturer focused on lift support production. Part number 612623 is cataloged for the specified GM SUV applications and should be matched to the vehicle fitment list before installation.
