Stabilus 4B-620732 Back Glass Lift Support

OE-Style Back Glass Lift Support

The Stabilus 4B-620732 back glass lift support is built for rear glass applications that use electrical terminals for defrost and wiper system power transfer. It combines gas-charged lift support action with controlled hydraulic damping to help the rear glass open and close smoothly on supported Chevrolet and GMC applications.

Precision Motion for Rear Glass Systems

Stabilus engineered this Elektro-Lift unit as an OE-equivalent replacement for vehicles originally equipped with rear glass power transmission components. The design uses an oil channeling system, a patented labyrinth piston, and a precision seal-guide system to maintain hydraulic damping and consistent motion control. For 1992-1994 Chevrolet Blazer and 1992-1994 GMC Yukon rear glass applications with electrical terminals for defrost, the 4B-620732 supports dependable operation and direct-fit service replacement.

This part cross-references Dayco 84190 for the same application.

Common Problems This Part Can Address

• Rear glass that drops too quickly when opened
• Weak or inconsistent lift support force at the back glass
• Loss of smooth motion in defrost-equipped rear glass systems
• Electrical connection issues at the rear glass terminals caused by worn original components
• Replacement needs for aging OE rear glass power transmission hardware

Installation Notes and Tips

Verify vehicle fitment by year, make, model, and rear glass electrical-terminal configuration before installation. Match the ball socket end fittings and terminal layout to the original part, and inspect the mounting points for wear or damage before connecting the new support. Because this unit uses spade terminals, confirm clean, secure electrical contact for the rear defrost and wiper system.
