Raise and hold the hood with smooth, controlled motion using the Stabilus Hood Lift Support 3B-137430 (also written 3B137430). This gas-charged lift support with dynamic damping speed control drops in as a direct-fit replacement for the 2005-2011 Cadillac STS — see the Buyer's Guide tab for engine-specific coverage. Built on the Lift-O-Mat design, it uses a longitudinal velocity-manifold groove pressed into the tube wall so gas flows around the piston with extension speed and damping engineered for this application, then narrows toward the end of the stroke for a gentle, controlled stop.
- Dynamic damping speed control: creates a fluid opening motion with no bouncing or jerking during cycling.
- Corrosion-resistant coatings: part coatings tested to automotive standards for corrosion resistance.
- Based on the OE design: intended to match proper fit, form, and function.
- Easy to install: requires no special tools; for best results, replace in pairs.
If a worn lift support that no longer holds the hood is the cause of your drooping or slow-rising hood, this replaces it.

Frequently Asked Questions
What vehicle does this hood lift support fit?
It is a direct-fit replacement for the 2005-2011 Cadillac STS. Check the Buyer's Guide tab to confirm the fit for your specific vehicle.
What does a hood lift support do?
It is a gas-charged strut that raises the hood and holds it open. This unit adds dynamic damping speed control for a smooth, controlled opening motion.
Should I replace both lift supports at once?
For best results, replace them in pairs. When one support weakens, the other is usually near the end of its life, so replacing both gives balanced, even support.
How do I know if my hood lift support is worn?
Signs it may need replacing include a hood that drifts down, rises slowly, or no longer stays open on its own. Diagnose the cause before replacing.
Are special tools required to install it?
No. It is easy to install and requires no special tools. Consult your vehicle service information for the correct procedure and any fasteners.
