Key Features

• Force Rating: 450 N – ideal for medium‑sized cargo compartments and passenger cars.
• Stroke Length: 485 mm – offers ample travel to accommodate varying load heights.
• Construction: Heavy‑duty steel housing with corrosion‑resistant coating, ensuring longevity in diverse climates.
• Compatibility: Designed for a wide range of vehicles, particularly the Mercedes-Benz C‑Class (S202) and similar models.
• Installation Type: Two‑piece assembly (inner cylinder & outer housing) that fits standard mounting brackets.

Technical Specifications

Installation Overview

The Stabilus 31872 is engineered for straightforward installation:

1. Mounting Bracket Preparation: Secure the provided brackets to the vehicle’s rear frame, ensuring alignment with the cargo lid hinge.
2. Attach Inner Cylinder: Slide the inner cylinder into the bracket’s socket and lock it in place using the supplied retaining clip.
3. Insert Outer Housing: Fit the outer housing over the inner cylinder, aligning the threaded ends. Tighten with a torque wrench to the manufacturer’s specification (typically 12 Nm).
4. Seal and Test: Apply a thin layer of grease to the pivot points, then open and close the cargo lid several times to confirm smooth operation.

Performance Benefits

• Consistent Lift: The gas spring’s controlled pressure ensures that the boot lid rises evenly, preventing wobble or uneven weight distribution.
• Reduced Wear: By absorbing impact forces, the spring reduces stress on hinges and seals, extending component life.
• Energy Efficiency: The precise force curve minimizes energy loss during operation, contributing to overall vehicle efficiency.
• Safety Assurance: Reliable closure pressure keeps the cargo area secure, preventing accidental lid opening while driving.

Compatibility Highlights

The Stabilus 31872 is specifically tailored for vehicles that require a moderate force gas spring. Its most common application is in the Mercedes-Benz C‑Class (S202) Kombi, but it also fits:

• Other Mercedes-Benz models with similar rear frame geometry.
• Passenger cars and light commercial vehicles that use a standard cargo lid hinge system.
• Custom installations where the user can adapt mounting brackets to match the spring’s dimensions.

Maintenance Tips

1. Regular Inspection: Check for visible corrosion or wear on the housing and cylinder. Replace if any damage is detected.
2. Lubrication: Apply a high‑temperature grease to pivot points every 12,000 km to maintain smooth motion.
3. Seal Integrity: Inspect seals for cracks or leaks; replace with OEM-compatible gaskets when necessary.
