Help your trunk lid rise in a fluid, controlled motion and stay open with the Stabilus trunk lid lift support, part number 4B-023549. This 15.89-inch gas-charged lift support uses dynamic speed control and is a direct-fit replacement for the 1999-2002 Audi TT and the 2000-2002 Audi TT Quattro.
- Dynamic damping speed control: Creates a fluid opening motion, with no bouncing or jerking during cycling.
- Corrosion-tested coatings: The part's coatings are tested to automotive standards for corrosion resistance.
- OE-based design: Based on the original equipment design for proper fit, form and function.
- Simple installation: Easy to install, with no special tools required.
This support is part of the Stabilus Lift-O-Mat line. A longitudinal groove called a velocity manifold is pressed into the tube wall, and gas flows through it around the piston. Extension speed and damping are engineered for this specific application. The groove profile gradually narrows toward the end of the stroke, which gives a gentle, controlled stop with minimal impact.
A trunk lid that won't stay open on its own, drifts down after opening, or feels heavy to lift may mean a lift support needs replacing. For best results, Stabilus recommends replacing lift supports in pairs. See the "Vehicles it fits" section for complete fitment details.
