KW Height Adjustable Spring Kit (HAS)
Height-adjustable spring set
The KW Height Adjustable Spring Kit is designed to lower the vehicle in conjunction with the original shock absorbers . Unlike conventional lowering spring kits, the KW HAS system allows for individual and stepless height adjustment within a tested adjustment range.
The solution uses vehicle-specific spring plates, KW lowering springs, compatible elastomers and dust protection systems. The vehicle's original shock absorber system – for example , electric or hydraulic suspension adjustment – remains fully functional.
Chassis adjustment – sporty, harmonious spring rates
KW Height Adjustable Spring Kits use high-quality springs made of chrome-silicon steel , whose spring rates are vehicle-specifically adapted to the original shock absorbers and axle loads.
When developing the spring kits, the different damping characteristics of the adaptive chassis are also taken into account so that the suspension works harmoniously in all driving modes. This makes the vehicle's driving feel more direct and dynamic without compromising comfort.
KW HAS spring kits are ideal for drivers who want a subtle lowering and the ability to adjust the ride height individually.
Stepless lowering
KW Height Adjustable springs allow for stepless lowering , similar to a coil spring suspension, but using the original shock absorbers. This is not possible with traditional fixed lowering springs.
The dust covers and spring plates included in the delivery are designed to support the maximum allowable lowering , which allows:
- sporty and balanced driving behavior
- preserved driving dynamics even in high-performance vehicles
- optimal operation without harmful stiffening of the platform
Available for models with and without EDC chassis.
Models without EDC only with front axle damper dimension 48.5 mm, does not fit 50mm models.
