Hold your liftgate steady at just the right angle with the Stabilus Interstop Liftgate Lift Support 4D-020594 (also written 4D020594), a 19.68-inch gas-charged strut with multiple stopping positions built into its stroke. It's a direct-fit replacement for the 1998-2006 Audi A4 Quattro, 2001-2002 Audi S4, and 2004-2005 Audi S4 — see the Buyer's Guide tab for engine-level fitment.

  • Multi-position hold: A longitudinal velocity-manifold groove pressed into the tube wall creates predefined stopping points, so the gate can be held open at multiple predetermined angles.
  • Coil-spring piston: A special coil-spring-supported piston package reduces extension force for easy stopping at desired points without added hardware.
  • Dynamic damping: Gas flow controlled by the groove geometry delivers smooth, controlled extension and gentle stops for this specific application.
  • Corrosion resistance: Part coatings are tested to automotive standards for corrosion resistance.

Based on the OE design for proper fit, form, and function, it installs easily and requires no special tools. Signs the original may need replacing include a gate that drifts down, won't stay up, or feels weak. For best results, replace in pairs.

Frequently Asked Questions

What vehicles does this lift support fit?

It's a direct-fit replacement for the 1998-2006 Audi A4 Quattro, 2001-2002 Audi S4, and 2004-2005 Audi S4. Check the Buyer's Guide tab to confirm fitment for your vehicle.

How does the multi-position hold work?

A longitudinal velocity-manifold groove pressed into the tube wall creates predefined stopping points along the stroke, letting the gate be held at multiple predetermined angles.

Should I replace both supports at once?

For best results, replace them in pairs. When one strut weakens the other is usually near the end of its life, so a matched pair gives balanced, even support.

What are signs this lift support is failing?

Common signs include a liftgate that slowly drifts down, won't stay open, or feels weak when raised. Diagnose the cause before replacing.

Do I need special tools to install it?

No. It's designed for easy installation and requires no special tools. Follow the vehicle service information for the correct procedure.
