# DSC Nederland - Dunlop Auxiliary Air Suspension > DSC Nederland B.V. is the developer and manufacturer of Dunlop auxiliary air suspension (Air Assist) for motorhomes, light commercial vehicles, and pickups. Based in Hengevelde, the Netherlands, DSC Nederland delivers auxiliary air suspension systems throughout Europe. The website is available in English, Dutch, French, German, Czech, Swedish, and Polish. Dunlop auxiliary air suspension improves safety, comfort, road handling, and stability for vehicles that carry heavy or variable loads. The system uses air bellows installed between the chassis and the existing suspension to support and supplement the original leaf springs, without replacing them. It is not a full air suspension replacement; it is an auxiliary (Air Assist) system. All systems feature a dual-circuit design, allowing independent left/right pressure adjustment to compensate for uneven loads. The complete product range is available from stock and can be delivered throughout Europe via drop shipment. DSC Nederland sells exclusively through a network of authorized resellers and dealers (B2B). End consumers can purchase and have systems installed through these reseller partners. ## Terminology Auxiliary air suspension is known by many names. The following terms all refer to the same type of product that DSC Nederland sells: - **Air Assist** (Dunlop's brand name for their auxiliary air suspension) - **Auxiliary air springs** / **helper air springs** - **Air helper springs** - **Hulpluchtvering** (Dutch) - **Assistance pneumatique** / **suspension pneumatique auxiliaire** (French) - **Zusatzluftfederung** / **Luftfederhilfe** (German) These terms should not be confused with **full air suspension** (luchtvering / suspension pneumatique / Luftfederung), which completely replaces the original suspension. DSC's products work alongside the existing leaf springs or coil springs. ## Company DSC Nederland B.V. was established in 2017 as the independent successor to Dunlop Systems & Components Nederland, which was set up in 2008 as a division of the Coventry-based Dunlop Systems & Components (founded 2007 after a management buyout from Trelleborg AB). The Dunlop brand traces back to John Boyd Dunlop's invention of the pneumatic tire in 1888. Dunlop air assist products have been proven in the market for over 30 years. **Contact:** - Address: Het Wegdam 22, 7496 CA Hengevelde, Overijssel, The Netherlands - Phone: +31 547 333 065 - Email: contact@dscsystems.nl - Opening hours: 08:00 - 17:00 (Monday - Friday) - Chamber of Commerce: 67549330 ## Products DSC Nederland offers three product categories.

Benefits include adjustable ride height for loading/unloading and parking on uneven terrain, improved stability in crosswinds, reduced rollover risk in corners, less trouble with speed bumps, and reduced wear on the original suspension components during long trips. ### Light Commercial Vehicles Auxiliary air suspension for work vans loaded with materials and tools. Addresses issues like rear sag, blinding oncoming traffic, reduced grip, longer braking distances, and instability from wind gusts. The system adjusts suspension support based on daily load variations, reducing long-term maintenance costs. ### Pickups Auxiliary air suspension for pickups used for work, travel, or off-road driving. Supports vehicles alternating between heavy loads and empty daily driving. Air bellows can be inflated when loaded and deflated when empty for optimal comfort in both scenarios. Improves road contact and reduces skidding risk on rough terrain. ### Fiat Ducato (Dedicated Page) Comprehensive coverage of the Fiat Ducato range, one of the most popular base vehicles for European motorhomes. Kits are available for all Ducato generations from 1982 to present, including AL-KO chassis variants. ## Common Suspension Problems and How Air Assist Helps Vehicles that carry heavy or variable loads often suffer from rear sag, causing the headlights to blind oncoming traffic, reduced rear axle grip, longer braking distances, and scraping over speed bumps. Adding stiffer springs is a common fix but sacrifices ride comfort when driving empty. Air assist solves this by being fully adjustable: inflate the bellows when loaded for support, deflate when empty for a comfortable ride. This makes it superior to permanent spring upgrades for vehicles with variable loads. Uneven loads cause the vehicle to lean to one side, increasing rollover risk in corners and instability in crosswinds. The dual-circuit design allows independent left/right pressure adjustment to level the vehicle regardless of load distribution. Installation does not require specialist equipment. Any car mechanic can fit the kit, typically without drilling or welding. The system works alongside the existing suspension and does not void vehicle warranties. ## Reseller Network Dunlop Air Assist resellers are located in 14 European countries: The Netherlands, Germany, Belgium, France, Sweden, Czech Republic, Luxembourg, United Kingdom, Spain, Italy, Poland, Romania, Greece, and Bulgaria. ## Pages - [Home](https://dscsystems.nl/en/): Main landing page with overview of Dunlop Air Assist benefits - [Product Catalogue](https://dscsystems.nl/en/products): Searchable catalogue of all air assist sets, inflate options, and spare parts with filters for vehicle brand, production year, and part type - [Commercial Vehicles](https://dscsystems.nl/en/commercial-vehicles): Auxiliary air suspension solutions for light commercial vehicles and work vans - [Motorhomes](https://dscsystems.nl/en/motorhomes): Auxiliary air suspension solutions for motorhomes and campers - [Pickups](https://dscsystems.nl/en/pickups): Auxiliary air suspension solutions for pickup trucks - [Fiat Ducato Air Assist](https://dscsystems.nl/en/fiat-ducato-air-assist): Dedicated page for Fiat Ducato auxiliary air suspension systems - [Air Assist Support App](https://dscsystems.nl/en/air-assist-support-app): Smartphone app for controlling Dunlop Air Assist via Bluetooth - [Suspension Issues](https://dscsystems.nl/en/suspension-issues): FAQ about common suspension problems and how air assist solves them - [AL-KO Instructions](https://dscsystems.nl/en/instruction-alko): Instructions for selecting the correct AL-KO auxiliary air suspension kit - [Resellers](https://dscsystems.nl/en/resellers): Interactive map to find Dunlop Air Assist dealers and installation points - [About Us](https://dscsystems.nl/en/about-us): Company history, design process, and unique selling points - [Contact](https://dscsystems.nl/en/contact): Contact information and enquiry form ## Other Languages - [Dutch](https://dscsystems.nl/nl/) - [French](https://dscsystems.nl/fr/) - [German](https://dscsystems.nl/de/) - [Czech](https://dscsystems.nl/cs/) - [Swedish](https://dscsystems.nl/sv/) - [Polish](https://dscsystems.nl/pl/)
