Specially designed for vehicles equipped with electronic damping systems. Our ASP spring kits allow users to easily replace their stock springs with adjustable spring perches and lowering springs. The kits allow ride height to be custom set using the provided adjustable spring platform while retaining the use of the OEM adjustable electronic damping systems.

The spring lengths and rates are designed to work in harmony within the OEM dampers travel and damping range. This approach results in a package that enhances handling, provides superior driver feedback and maintains the original OEM ride quality. Furthermore, since these components directly replace the OEM items, there will be no malfunction or error messages displayed on the vehicle's dashboard.
