• MERCEDES‑BENZ Class E and other luxury sedans – providing premium cargo lift performance.
• Light commercial vans – supporting heavy freight loads with reliable force.
• Passenger hatchbacks – enhancing everyday usability for families and commuters.

Its modular mounting system allows easy integration into existing chassis designs, requiring minimal modification to the vehicle’s frame or body panels.

Installation Guidelines

1. Preparation: Clean all mounting surfaces and verify that the piston rod aligns with the designated opening point on the cargo area.
2. Mounting: Secure the spring housing to the vehicle frame using the supplied bolts. Torque specifications should match the manufacturer’s recommendations for optimal performance.
3. Alignment: Ensure that the piston rod is perfectly vertical to avoid uneven load distribution.
4. Testing: Operate the cargo area several times to confirm smooth lift and proper return action. Check for any abnormal noises or resistance.

Maintenance & Longevity Tips

• Inspect seals periodically; replace O‑rings if they show signs of wear or cracking.
• Avoid exposing the spring to extreme chemical environments that could corrode the steel body.
• Keep the mounting area free from debris and moisture to prevent rust buildup.
