VB-CoilSpring suspension: Everything you need to know

VB-CoilSpring - Coil spring suspension - RosmiaCoil springs to support your suspension

VB-CoilSpring is the ideal suspension solution for vehicles that are constantly heavily laden but don’t carry variable loads. The addition of the VB-CoilSprings will increase your vehicle’s ride height, improve stability and reduce body roll and pitching. Vibrations and bumps on the road are also better absorbed, providing a more even ride.

Why VB-CoilSpring?

Your suspension is a critical component for the safe running of your vehicle, so if your original suspension system is unable to support its laden weight and ride at an even level, its movements can feel unstable and abrupt. The vehicle can end up sagging and you risk hitting the bump stops or wearing out the tyres. VB-CoilSpring is the ideal suspension upgrade for vehicles that are always heavily laden but don’t carry variable loads because it’s a non-adjustable system.

TowingRide Height

Vehicles that sag under excess weight are more likely to hit the bump stops, resulting in poor vehicle handling and an uncomfortable ride. VB-CoilSpring increases your vehicle’s ride height under load, preventing it from hitting the bump stops and improving ground clearance.


VB-CoilSpring at the rear is a particularly good choice if your vehicle is solely and constantly used for towing, because the hitch-weight of a trailer can drag the rear end of your vehicle down, causing it to sag. The addition of rear VB-Coilsprings will help to even out your ride height under load and improve road handling. For an adjustable solution (if your vehicle is only occasionally used for towing) VB-SemiAir or VB-FullAir may provide a better solution.

In vehicles that already have coil spring suspension, the original coil springs are removed and replaced with the reinforced VB-Coilsprings; whereas in vehicles with leaf suspension, additional coil springs are mounted to the existing leaf springs, reinforcing the original suspension. Your VB-CoilSpring kit will come with all the necessary certification and credentials, including VOSA and VCA, so you can rest assured of the quality of your upgraded suspension system.

Technical Tip: The right reinforced coil spring for your vehicle.

VB-CoilSpring - Coil spring suspension

Helper and reinforced coil springs – also known as the VB-CoilSpring – are suspension systems that support or reinforce the existing suspension in order to correct a suspension problem. Is your vehicle always (heavily) laden? For example, do you regularly travel in a service vehicle – so your vehicle is your workshop and transport combined? In this case, the VB-CoilSpring can be an excellent option.

Two coil spring versions available

Our VB-CoilSpring is available in two versions: the replacement spring and the helper spring.

  • The replacement spring
    • The name ‘replacement spring’ more or less speaks for itself. When fitting a replacement spring, the original coil spring is ‘replaced’ by a reinforced version.
  • The helper spring
    • When a helper spring is fitted, the original suspension is retained. A helper spring is always installed alongside the original suspension and acts to reinforce the original suspension.

Replacing the original coil spring with a replacement spring – or installing a helper spring – will ensure that your vehicle returns to its original (or higher) ride height in both cases. The spring travel will increase, stability is improved and comfort enhanced. The reinforcement to the spring force is permanent and cannot be adjusted, which means that the VB-CoilSpring is the ideal option for vehicles that are always (heavily) laden.

Which coil spring version is best for your vehicle?

For vehicles with coil springs, either a helper spring or a replacement spring can be fitted. In the case of a vehicle with leaf springs, it is only possible to fit a helper spring.

Precise axle weights are required to then determine which version you need for your vehicle. Based on this, you will get an appropriate and specific recommendation on whether the VB-CoilSpring is the best option to solve your suspension problems. To get the precise axle weights, the vehicle needs to be weighed on a weighbridge or on weighing plates in a garage. Unfortunately, the vehicle typeplate is not sufficient here, since it only states the maximum permissible weights, not the exact weights. Our engineers at Rosmia will be able to advise you accordingly based on these precise axle weights.

Why VB-CoilSpring

Do you always drive with a heavy load? The heavy load causes the vehicle to sag, which reduces the spring travel and makes the vehicle more likely to bounce when driving over rough surfaces or speed bumps, for example.

Helper and reinforcement springs are suspension systems that support or reinforce the existing suspension system in order to correct suspension problems. Our helper and reinforcement springs – also called VB-CoilSpring – are either fitted to the existing leaf suspension or coil spring suspension, or they replace the original coil spring suspension. Reinforcement springs mainly ensure that the vehicle returns to its original ride height or higher. This increases spring travel and thus improves stability and, to some extent, comfort levels.

VB-CoilSpring is a good option for vehicles that are always (heavily) laden and have to carry variable loads every once in a while. This is because the reinforcement of the spring force is permanent and cannot be adjusted. Both systems are available for both the front and rear axles of certain types of vehicles.
