Hold the rear glass open and take the strain out of loading with the Stabilus Back Glass Lift Support 4B-030091 (also written 4B030091), a 17.60-inch hydraulically dampened, gas-charged lift support. It's a direct-fit replacement for the 1999 Cadillac Escalade; 1992-1994 Chevrolet Blazer; 1992-1999 Chevrolet C1500, C2500, K1500 and K2500 Suburban; 1995-1999 Chevrolet Suburban 1500 and Tahoe; 1992-1999 GMC C1500, C2500, K1500 and K2500 Suburban; and 1992-1999 GMC Yukon — see the Buyer's Guide tab for engine details and the full list.

  • Patented Labyrinth Piston: provides clog-free, smooth operation through the full opening and closing cycle.
  • Clog-free design: helps prevent binding caused by contamination.
  • Corrosion-tested coatings: part coatings are tested to automotive standards for corrosion resistance.
  • OE-based design: built on the OE design for proper fit, form and function, and installs easily with no special tools.

Stabilus Lift-O-Mat pairs an oil-channeling system with the patented labyrinth piston, tuning oil viscosity and piston configuration for this application to deliver controlled, refined motion. A worn support that drifts down, feels weak, or no longer holds the glass up is a sign it may need replacing. For best results, replace lift supports in pairs.

Frequently Asked Questions

What is the Stabilus 4B-030091?

It's a 17.60-inch back glass lift support — a hydraulically dampened, gas-charged strut that helps hold the rear glass open and dampens its motion during opening and closing.

Which vehicles does it fit?

Should I replace both lift supports at once?

For best results, Stabilus recommends replacing lift supports in pairs so both sides provide even, balanced support.

What makes the Lift-O-Mat design different?

It uses an oil-channeling system with a patented labyrinth piston, providing clog-free, smooth motion with controlled hydraulic damping tuned for the application.

How do I know when a lift support needs replacing?

Signs it may need replacing include the glass drifting down on its own, feeling weak, or no longer staying held open. Diagnose the cause before ordering.
