The ACS front axle strut – greater travelling comfort for vans and motorhomes

You’re off on your well-deserved holiday, driving comfortably across the country in your motorhome. But despite all the anticipation and the fantastic views, you never quite experience that much hoped-for relaxation, because every bump seems to make the vehicle jolt and the dishes clink in the cupboards.

Sound familiar? If so, you probably still have the manufacturer’s original springs installed in your van or motorhome. These are generally designed for functional, commercial use. True travelling comfort is naturally not to be expected on longer tours.

That is why AL-KO has developed an easy-to-retrofit but very effective solution for vans and motorhomes: the AL-KO Comfort Suspension front axle strut, or ACS for short. It significantly improves the driving comfort and stability of the vehicle on longer journeys. This not only leads to a much more pleasant travelling experience, but also ensures greater driving safety, a better cornering response, and fewer roll movements.

The ACS spring strut’s advantages at a glance:

• A special damper that is optimally calibrated to the vehicle’s weight absorbs the energy of any bumps or potholes etc., while the shock absorber dampens the spring’s movement to ensure a stable driving response.
• The ACS is able to optimise the vehicle's standing height at the front axle and offers impressive suspension comfort.
• Driving stability and safety are improved as any rolling or pitching movements are reduced, as is noise generation in the vehicle interior.
• The robust and durable construction is completely maintenance-free and protects the vehicle, body and load.
• The spring strut reduces vibrations on the steering wheel and improves the driving experience through excellent road holding. This enables relaxed, effortless travel.

What is so special about the ACS spring strut from AL-KO?

The AL-KO ACS spring strut is a unique combination of high-performance damper and coil spring, which is precisely calibrated to the vehicle’s actual weight. This allows the damper to compensate for most of the bumps in the road, which means that significantly fewer vibrations can be felt on the steering wheel. It also reduces noise in the interior.

How exactly does the ACS spring strut work?

The principle of the ACS front axle strut is based on optimised independent wheel suspension and wheel guidance, achieved through specially calibrated shock absorbers and springs. This function improves the motorhome’s driving characteristics and is specifically tailored to the vehicle’s actual size and weight.

The special feature of the ACS spring strut is that its spring effect and damping are designed precisely for the respective permissible axle load. This increases driving comfort on the front axle, which often leaves a lot to be desired, especially in vans such as the Fiat Ducato and identical models from other brands. AL-KO can provide just the right solution for some vehicle types and weight classes.

Numerous internal and independent driving tests have proven that it softens hard impacts. In addition, a vehicle with ACS has a more sensitive contact with the road surface than it would with the original Fiat springs, for example. The motorhome also dips less at the front when braking hard and leans less when cornering at speed.

For which vehicles is the ACS front axle strut suitable?

The ACS technology is specially designed for vehicles with AL-KO chassis as well as Fiat Ducato, Peugeot Boxer and Citroën Jumper type X250 (model year 2006 or later) original chassis or vans. It is suitable for both 2-axle and 3-axle vehicles and replaces the standard original front axle strut.

Can I retrofit an ACS spring strut?

In principle, the ACS front axle strut can be retrofitted to most of the models mentioned. To clarify your vehicle’s specific installation situation, please contact us for a no-obligation consultation!
