Hold your Volvo's rear liftgate open with smooth, controlled motion using the Stabilus Liftgate Lift Support 5B-643870, a gas-charged support that drops in as a direct-fit replacement for the 2008-2016 Volvo XC70. This is the right-side (R) unit, measuring 11.79 inches, and it uses dynamic damping speed control for a fluid opening motion with no bouncing or jerking during cycling.

  • Dynamic damping speed control: creates a fluid opening motion with no bouncing or jerking as the gate cycles.
  • Lift-O-Mat by Stabilus: a longitudinal groove (velocity manifold) pressed into the tube wall lets gas flow around the piston, and the profile narrows toward the end of the stroke for a gentle, controlled stop.
  • Corrosion resistance: part coatings tested to automotive standards.
  • Easy install: requires no special tools; based on the OE design for proper fit, form, and function.

Signs a lift support may need replacing include a liftgate that drifts down, won't stay up, or opens and closes slowly. Sold individually — for best results, replace both liftgate supports as a pair.

Frequently Asked Questions

What vehicle does this lift support fit?

It is a direct-fit replacement for the 2008-2016 Volvo XC70. See the Buyer's Guide tab for full engine-level fitment details.

Which side is this lift support for?

This is the right-side (R) liftgate lift support. For best results, Stabilus recommends replacing supports in pairs, so consider ordering the matching side as well.

What does the Lift-O-Mat dynamic damping do?

A groove pressed into the tube wall lets gas flow around the piston, and the profile narrows toward the end of the stroke, delivering a fluid opening motion and a gentle, controlled stop.

How do I know if my lift support is failing?

Common signs include a liftgate that drifts down, won't stay open, or moves slowly. If a worn lift support is the cause, this unit replaces it.

Do I need special tools to install it?

No. This lift support is designed for easy installation and requires no special tools. Consult your vehicle's service information for the correct procedure.
