Hold the trunk lid open and control its motion with the Stabilus Trunk Lid Lift Support 4B-8908CO, a gas-charged Lift-O-Mat unit built on the OE design to match the original part's fit, form, and function on the 1994-1997 Volvo 850 (all engines). A support that drifts closed, feels weak, or lets the lid drop on its own is a sign this part may need replacing.
- Dynamic damping speed control: a longitudinal velocity-manifold groove pressed into the tube wall channels gas around the piston, so the lid opens fluidly with no bouncing or jerking through the cycle; the groove narrows toward the end of the stroke for a gentle, controlled stop.
- Gas-charged design: rated to a maximum force of 67 lb.
- Application-matched ends: a nylon hook-blade end (End 1) and a steel blade-with-bushing end (End 2).
- Sized for the job: 18.31 in extended, 10.63 in compressed, with a 7.68 in stroke.
- Corrosion-resistant coatings: part coatings tested to automotive standards for corrosion resistance.
It installs without special tools, and mounting hardware is not included. The listed application uses two supports; for best results replace them in pairs so both sides move evenly. Country of origin: Germany.
