Lesjöfors 8056828 Bonnet – Premium Gas Spring for Mercedes‑Benz GLK

The Lesjöfors 8056828 Bonnet is a high‑performance gas spring (mola pneumática) designed specifically to support the front hood of the Mercedes‑Benz GLK-Class X204 (model years 2008–2015). It delivers smooth, reliable lift and secure retention for the vehicle’s hood, ensuring both safety and convenience during routine maintenance or emergency repairs.

Key Technical Specifications

• Model Compatibility: Mercedes‑Benz GLK-Class X204 (2008–2015), 2.0L, 2.2L, 3.0L, 3.5L engines – both left and right side installations.
• Type: Gas spring (also known as a hydraulic hood damper or amortizzatore pneumatico). Provides controlled lift force to counteract the weight of the hood.
• Construction Material: High‑strength steel alloy with corrosion‑resistant coating, ensuring durability under varying temperature and humidity conditions.
• Load Capacity: Designed to handle the full weight of a standard GLK hood (approximately 30–35 kg), maintaining consistent performance over thousands of cycles.
• Operating Range: Full extension from fully closed to fully open position, with smooth transition and minimal noise.

Functional Advantages

The Lesjöfors 8056828 Bonnet offers several critical benefits that enhance both user experience and vehicle safety:

1. Controlled Lift: The gas spring exerts a calibrated force, allowing the hood to open slowly and safely without slamming.
2. Secure Retention: When fully opened, the spring holds the hood in place, preventing accidental closure during maintenance or while parked.
3. Reduced Wear on Hinges: By sharing the load with the gas spring, the mechanical hinges experience less stress, extending their service life.
4. Easy Installation: The unit is engineered to fit standard mounting points on the GLK hood assembly, requiring minimal modification.
5. Low Maintenance: With no moving parts exposed to the elements, the spring requires virtually no upkeep beyond periodic inspection.

Installation Overview

Installing the Lesjöfors 8056828 Bonnet involves a straightforward procedure that can be completed by an experienced automotive technician or a knowledgeable DIY enthusiast:

1. Preparation: Secure the vehicle on a flat surface, engage the parking brake, and remove any existing gas spring if present.
2. Mounting: Align the new spring with the designated mounting brackets on the hood frame. The spring’s threaded ends fit into pre‑drilled holes; use the supplied bolts to secure it firmly.
3. Adjustment: Once mounted, gently lift the hood to ensure smooth operation. Adjust the tension by rotating the threaded end if necessary (some models allow fine tuning).
4. Testing: Open and close the hood several times to confirm that the spring holds the hood in place and that there is no excessive play or noise.

Compatibility with Other Models

While the Lesjöfors 8056828 Bonnet is specifically engineered for the Mercedes‑Benz GLK-Class X204, its design shares similarities with other Lesjöfors and Kilen gas springs used in various Mercedes models. However, due to differences in hood weight and hinge geometry, it is recommended to use the exact model number for optimal performance.

Material Quality and Durability

The spring’s construction employs a high‑strength steel alloy that resists corrosion through a protective coating. This ensures longevity even in harsh climates or when exposed to road salts and moisture. The internal gas chamber is sealed with a robust valve system, preventing leaks and maintaining consistent pressure over the product’s lifespan.

Maintenance Tips

• Regular Inspection: Check for visible damage, rust, or loose fittings every 12 months.
• Cleaning: Wipe the exterior with a damp cloth; avoid abrasive cleaners that could scratch the protective coating.
• Tightening: Re‑tighten mounting bolts if you notice any looseness after repeated use.
