StrongArm Back Glass Lift Support

StrongArm Back Glass Lift Supports: Precision Engineering for Your Rear Window

When the rear window glass on your SUV, wagon, or truck starts to sag, drop unexpectedly, or refuse to stay open, a worn-out back glass lift support is almost always to blame. Back glass lift supports are pressurized gas-charged cylinders that hold your rear window in the open position — and few brands take that job more seriously than StrongArm.

StrongArm is the industry standard for quality and long-lasting performance, and stands as the first and original aftermarket gas-charged lift support on the market — developed from the ground up to meet OE standards for gas pressure, corrosion resistance, and ease of operation. That heritage matters especially in the back glass application, where the lift support must contend with repeated open-and-close cycles, temperature swings, and the added weight of glass panels that can vary significantly from vehicle to vehicle.

What Sets StrongArm Back Glass Lift Supports Apart

StrongArm's back glass lift supports are built around a stack of carefully engineered components that work together to deliver smooth, consistent lift every time. Key construction features include:

• Chromium steel center shafts: StrongArm lift supports feature durable chromium steel center-shafts, which add mechanical strength and excellent corrosion resistance.
• Teflon seal rings and O-ring piston seals: Teflon seal rings enhance gas and oil pressure sealing, while bushings are precisely fitted to piston rods for longer operating life and durable O-ring piston seals prevent piston leakages.
• Self-cleaning piston assemblies: These lift supports are outfitted with self-cleaning piston assemblies, which automatically open up to keep orifices clear from contamination.
• Electrostatically painted, heat-treated bodies: Their bodies are coated in electrostatic paint and heat-treated to last for tens of thousands of miles.
• High-pressure gas charge: StrongArm gas-charged lift supports typically store a gas charge of over 1500 PSI and cannot be compressed by hand.
• Overload testing: After being assembled, each gas spring is subjected to overload tests to ensure the ultimate structural strength and safety of use.

Each StrongArm lift support is custom engineered and manufactured beyond industry standards to provide smoother operating and longer lasting performance. This is particularly critical for back glass applications, where a generic or improperly rated support can allow the heavy rear window to slam shut — creating a serious safety hazard.

Exact Fit, No-Hassle Installation

StrongArm back glass lift supports feature an exact fit original equipment design that guarantees correct fit and function, engineered and built to meet or exceed original equipment quality standards, and are individually tested for performance and reliability.

StrongArm lift supports are designed for the everyday driver to be installed in minutes with no special tools required. Whether you drive a full-size SUV with a powered rear glass or a classic wagon with a manually operated back window, there's a StrongArm part engineered specifically for your application. Lift supports should be replaced in pairs to ensure safe, reliable support of your hood, hatch, or liftgate.

When to Replace Your Back Glass Lift Support

On average, lift supports last approximately five years. As your vehicle's mileage increases, they may begin to work only intermittently — and once they start failing, it can be difficult to tell whether they are strong enough to function, or whether the raised window will fall back down and slam shut, causing injury. Lift supports lose roughly 3% of their power annually, and this can be further impacted by extreme conditions — colder temperatures in particular accentuate power loss over time, leading to product failure.
