Stabilus Liftgate Lift Support P/N:5B-3958IA
Keep the rear hatch rising smoothly and holding open with the Stabilus Liftgate Lift Support 5B-8066BB, a hydraulically dampened, gas-charged lift support measuring 10.79 inches. It installs as a direct-fit replacement for the 1988-1993 Mercedes-Benz 300TE and the 1994-1995 Mercedes-Benz E320 — see the Buyer's Guide tab for engine-level details.
Part of the Stabilus Lift-O-Mat line with hydraulic damping, this unit uses an oil-channeling system and the patented labyrinth piston, tuned with a specific oil viscosity and piston configuration for controlled motion on this application. Because lift supports work as a pair, Stabilus recommends replacing both sides together for balanced operation.
