STABILUS 596311 – Premium Gas Spring for Mercedes-Benz E-Class
The STABILUS 596311 is a high‑performance gas spring engineered specifically for the rear hatch and cargo area of the Mercedes‑Benz E‑Class (S211). Designed with precision engineering, this component delivers reliable lift, smooth operation, and long‑term durability under demanding conditions.
Key Technical Specifications
- Spring Force: 1550 N (1.55 kN) – provides optimal lifting power for the hatch and cargo lid.
- Stroke Length: 344.5 mm – matches the exact travel required by the E‑Class rear architecture.
- Housing Material: High‑strength alloy steel with corrosion‑resistant coating, ensuring resistance to environmental factors such as humidity and road salt.
- Operating Temperature Range: –40 °C to +80 °C – suitable for both cold climates and hot summer conditions.
- Installation Type: Direct fit with standard mounting brackets; no modification of the vehicle’s frame required.
Design Features & Engineering Excellence
The STABILUS 596311 incorporates several advanced design elements that set it apart from generic aftermarket springs:
- Dual‑Stage Compression: The spring’s internal geometry allows for a smooth transition between the initial lift and the final locking position, reducing noise and vibration.
- Pre‑Load Adjustment: A built‑in adjustment mechanism lets technicians fine‑tune the spring tension to match vehicle weight variations or aftermarket accessories.
- Sealed Gas Chamber: The gas cylinder is hermetically sealed, preventing leaks and ensuring consistent performance over thousands of cycles.
- Modular Mounting System: Compatible with both left‑hand and right‑hand side installations, making it versatile for different vehicle configurations.
Compatibility & Vehicle Integration
This gas spring is specifically calibrated for the Mercedes‑Benz E‑Class (S211) series. It fits seamlessly into the following models:
- E‑Class C‑Model (Vf211)
- E‑Class T‑Model (S211)
- All variants with standard rear hatch and cargo lid dimensions.
Because of its precise dimensional match, the STABILUS 596311 eliminates the need for custom fabrication or additional hardware. It is a drop‑in replacement for OEM gas springs that have worn out over time.
Installation Guide (Overview)
- Preparation: Secure the vehicle on a flat surface and disconnect the battery to avoid accidental release of stored pressure.
- Removal of Old Spring: Loosen the mounting bolts, carefully detach the old gas spring, and note its orientation for correct placement of the new unit.
- Mounting the STABILUS 596311: Align the new spring with the mounting brackets. Tighten bolts to the manufacturer’s torque specifications (typically 30 Nm).
- Pressure Release Check: Verify that the gas cylinder is fully seated and that no pressure leaks are present.
- Functional Test: Open and close the hatch several times, ensuring smooth operation and proper locking at the top position.
Performance Benefits
- Consistent Lift: The 1550 N force guarantees that the hatch opens fully even when carrying heavy cargo or aftermarket accessories.
- Smooth Operation: Dual‑stage compression reduces abrupt movements, enhancing user comfort and safety.
- Long Life Span: High‑quality materials and sealed gas chamber extend service life beyond typical aftermarket alternatives.
- Low Maintenance: Once installed, the spring requires no routine servicing; it is designed to operate reliably for thousands of cycles.
