Design Features

The Stabilus 12815 incorporates a sealed gas chamber that prevents leaks and ensures consistent pressure throughout the life of the spring. The internal piston is engineered with a low‑friction coating, reducing wear and extending service life. The spring’s compact profile allows it to be installed in tight spaces without compromising the vehicle’s interior aesthetics.

Compatibility

This gas spring is specifically engineered for the Citroën C4 Picasso (both first and second generation, UD variants). It fits the following reference numbers:

• 8731P2, 8731P4, 8731T0, 8731T1
• 9654433480, 9654433580, 9687236380

Because of its standardised mounting dimensions, it can also be adapted to other vehicles with similar hatch geometry by using appropriate brackets.

Installation Overview

1. Preparation: Remove the existing hatch latch or gas spring assembly. Keep all hardware for reuse.
2. Mounting: Attach the new Stabilus spring to the vehicle’s rear frame using the supplied mounting brackets. Ensure that the threaded ends are fully seated and torqueed to manufacturer specifications.
3. Alignment: Verify that the hatch aligns correctly with the frame and that the spring’s piston is centered.
4. Testing: Open and close the hatch several times to confirm smooth operation. Adjust tension if necessary by rotating the spring’s mounting nut.
5. Final Check: Inspect for any play or abnormal noise. Tighten all fasteners again after the first few cycles.

Benefits of Using Stabilus 12815

• Low Maintenance: No lubrication required; the sealed design eliminates the need for regular servicing.

Maintenance Tips

Although the Stabilus 12815 is designed for minimal upkeep, periodic checks can extend its lifespan:

• Inspect the mounting bolts for tightness every 10,000 km.
• Check the hatch alignment; adjust if misaligned to prevent uneven wear.
