Hold your trunk lid up and let it open with a smooth, controlled motion using the Stabilus Trunk Lid Lift Support 5B-134323, a 12.56-inch gas-charged lift support with dynamic speed control. It's a direct-fit replacement for the 2005-2011 Cadillac STS — see the "Vehicles it fits" section for engine-level detail. Built on the OE design to match proper fit, form and function.
If your original lift support has weakened and no longer holds the trunk lid up, this Lift-O-Mat by Stabilus is designed to restore that controlled support.

What vehicle does the Stabilus 5B-134323 fit?
It is a direct-fit replacement for the 2005-2011 Cadillac STS. Check the "Vehicles it fits" section to confirm the application for your specific vehicle.
What does this trunk lid lift support do?
It is a gas-charged strut that supports and cushions the trunk lid, holding it up and controlling its opening motion through Stabilus dynamic damping speed control.
How does the dynamic damping work?
A velocity-manifold groove pressed into the tube wall lets gas flow around the piston at a tuned rate, and the groove narrows toward the end of the stroke for a gentle, controlled stop.
Should I replace both lift supports at once?
Stabilus recommends replacing in pairs for best results, since a matched pair provides even, balanced support and opening motion.
Are special tools required to install it?
No. This lift support is easy to install and requires no special tools. Consult the vehicle service information for the correct procedure.
