Key Technical Specifications

• Force Rating: 340 Newton (76 lb)
• Stroke Length: 120–150 mm (varies by installation)
Operating Temperature Range: –40 °C to +80 °C
• Material Composition: High‑strength steel housing with a corrosion‑resistant coating; internal gas chamber filled with nitrogen for consistent pressure.
• Mounting Type: Standard 3‑point mounting system compatible with OEM and aftermarket brackets.
• Weight: Approximately 0.8 kg (1.76 lb)

Design Features & Engineering Excellence

The LIFT‑O‑MAT 340 Newton Gas Strut incorporates several design elements that set it apart from conventional springs:

• Dual‑Stage Compression: The strut offers a smooth transition between the initial lift and the final lock position, reducing impact forces on the rear cover.
• Low Friction Bearings: Integrated ball bearings minimize wear and extend service life, even under frequent opening/closing cycles.
• Sealed Gas Chamber: The nitrogen‑filled chamber prevents moisture ingress, ensuring consistent performance over time.
• Compact Footprint: Its slim profile allows installation in tight engine bay or cargo area spaces without compromising structural integrity.

Applications & Vehicle Compatibility

This gas strut is engineered to fit a broad spectrum of vehicles, particularly those requiring robust rear‑cover support. Common applications include:

• Rear Cover / Tailgate Lift: Provides effortless opening and secure locking for passenger cars.
• Cargo Area Support: Enhances load stability in vans and hatchbacks by maintaining a firm cargo floor.
• Boot / Cargo Door Assistance: Improves ergonomics for users, especially in compact or sub‑compact models where space is limited.

Vehicle compatibility examples (not exhaustive):

• Opel Astra H (various engine configurations)
• Vauxhall Astra H and related models
• Other compact cars with similar rear cover geometry

Installation Overview

Installing the LIFT‑O‑MAT 340 Newton Gas Strut is straightforward for technicians familiar with automotive suspension components. The process typically involves:

1. Removal of Existing Spring: Detach the old gas spring using a suitable wrench or socket set.
2. Mounting New Strut: Align the mounting brackets and secure them with bolts, ensuring torque specifications are met.
3. Adjustment of Stroke: If necessary, adjust the upper and lower stops to achieve the desired lift height.
4. Testing: Operate the rear cover repeatedly to confirm smooth action and proper locking.

Maintenance & Longevity

The LIFT‑O‑MAT 340 Newton Gas Strut is designed for low maintenance. However, periodic checks can extend its lifespan:

• Visual Inspection: Look for signs of corrosion or wear on the housing and mounting points.
• Lubrication: Apply a light spray of high‑temperature grease to the bearing surfaces every 12 months.
• Pressure Check: If the strut feels sluggish, consider recharging the gas chamber (typically performed by a qualified service center).

Performance Benefits

• Enhanced User Comfort: The controlled lift reduces the effort required to open heavy rear covers.
• Improved Safety: A firm lock prevents accidental opening during vehicle operation.
• Durability: High‑quality materials and sealed construction resist environmental factors such as humidity, temperature extremes, and road salt.
• Versatility: Suitable for both OEM installations and aftermarket upgrades, making it a popular choice among automotive enthusiasts.
