Innovative Independence: The HY4 Difference
Forget complex, centralized hydraulics. The revolutionary AL-KO HY4 system gives each of its four steady legs its own dedicated pump unit.
What does this mean for you?
- Smarter Installation: The independent units can be mounted flexibly near each leg, drastically reducing installation time and cost.
- Cleaner Interior: Say goodbye to long hydraulic lines and the need to drill holes inside your vehicle. Your interior stays intact!
- Future-Proof: The entire HY4 system is easy to remove and reinstall on your next vehicle, making it a valuable, long-term investment.
Certified Quality and Reliability
True to the AL-KO promise of "Quality for life," their engineers think further ahead. The HY4 (and HY2) are the first hydraulic levelling support systems to receive a clearance certificate from Mercedes-Benz. This is your assurance that the system maintains all critical brand values, including safety, operational stability, and driving dynamics.
Level, No Matter What
Uneven ground, soft grass, or loose gravel are no problem. The HY4's powerful hydraulics effortlessly compensate for any terrain or incline, guaranteeing a perfectly level, stable stand every time.

Weighing function and app control for HY4
The weighing function for the AL-KO HY4 prevents incorrect loading and dangerous overloading of motorhomes and vans. The system measures the gross weight and the respective axle load via measuring points on the longitudinal and transverse axes. This makes complying with weight limits easy and ensures payloads in the vehicle are optimally stowed. Control and display are via the AL-KO 2LINK app, which can be downloaded free of charge onto your own smartphone. This is based on installing the AL-KO 2LINK box with a Bluetooth interface.
Following this upgrade, it is even possible to level the vehicle via the 2LINK app. The smartphone user interface is similar to the standard remote control interface, and thus still very easy to use.
HY4 Weighing Function at a Glance:
✅ Total vehicle weight, front axle weight and rear axle weight are calculated separately
✅ System control and display via the AL-KO 2LINK app (available free of charge for iOS and Android)
✅ Measuring accuracy up to 3%
✅ Can be retrofitted to existing systems
✅ All the existing benefits of AL-KO HY4 remain unaffected
✅ For vehicles up to 6T
