Lesjöfors 8115665 Bonnet – Precision Engineering for the Citroën DS4

The Lesjöfors 8115665 Bonnet is a high‑performance gas spring designed specifically to support and lift the bonnet of the Citroën DS4 family. Engineered with meticulous attention to detail, this component delivers smooth operation, reliable load handling, and long‑term durability for both new vehicles and aftermarket installations.

Key Functional Characteristics

• Load Capacity: Capable of supporting the full weight of a standard DS4 bonnet while maintaining consistent lift height throughout its travel range.
• Travel Range: Offers a calibrated stroke that ensures the bonnet opens fully without over‑extension, protecting the vehicle’s front fascia and interior panels.
• Pressure Regulation: Equipped with an internal gas chamber that maintains pressure under varying temperature conditions, preventing sagging or excessive stiffness.
• Corrosion Resistance: Constructed from high‑grade steel alloys treated with anti‑rust coatings to withstand exposure to road salts and environmental elements.
• Installation Compatibility: Designed to fit seamlessly into the original mounting points of the DS4, eliminating the need for extensive modifications or custom brackets.

Material Composition & Manufacturing Excellence

The bonnet gas spring is fabricated from a blend of stainless steel and alloyed chrome plating, ensuring both structural integrity and aesthetic harmony with the vehicle’s exterior. The internal piston rod features a hardened surface finish that resists wear, while the outer housing incorporates a precision‑machined bore to guarantee smooth reciprocation.

During production, each unit undergoes rigorous pressure testing and thermal cycling procedures. These tests confirm that the spring maintains its specified force curve across temperature ranges from -40 °C to +80 °C, a critical requirement for vehicles operating in diverse climates.

Installation Guide – Step‑by‑Step

1. Preparation: Remove the existing bonnet support mechanism. Clean all mounting surfaces to eliminate debris and ensure proper alignment.
2. Mounting the Spring: Position the Lesjöfors 8115665 Bonnet onto its designated bracket. Secure it with the supplied fasteners, tightening to the manufacturer’s torque specifications.
3. Alignment Check: Verify that the bonnet sits level when closed and opens fully without obstruction. Adjust if necessary by fine‑tuning the mounting screws.
4. Functional Test: Open and close the bonnet several times to confirm smooth operation, consistent lift height, and absence of binding or excessive noise.

Compatibility Overview

The Lesjöfors 8115665 Bonnet is specifically engineered for the Citroën DS4 series, including:

• DS4 1.6 L (114 HP) – 2012‑2015 models
• DS4 1.6 L (156 HP) – 2011‑2015 models
• DS4 1.6 L (200 HP) – 2011‑2015 models
• DS4 2.0 L (136 HP) – 2011‑2015 models
• DS4 2.0 L (180 HP) – 2014‑2015 models
• DS4 Crossback variants – 2014‑2015 models

All these configurations share identical bonnet mounting geometry, allowing the Lesjöfors 8115665 Bonnet to be a universal fit across the DS4 lineup.

Performance Benefits for Vehicle Owners

• Enhanced Safety: By maintaining proper bonnet height, the spring reduces the risk of accidental contact with road debris or pedestrians during operation.
• Improved Aesthetics: The smooth lift action preserves the vehicle’s front profile, preventing visible sagging that can detract from its appearance.
• Reduced Maintenance: With robust corrosion protection and low‑friction components, the spring requires minimal upkeep compared to conventional mechanical lifts.
• Longevity: Designed for a lifespan exceeding 10,000 operating cycles, ensuring long‑term reliability even under heavy usage.
