SuperSprings are adjustment free helper springs that mount above your vehicles factory springs to provide additional load support and to reduce body roll by up to 30%. This unique stabilizing system uses a shackle with a roller on each end of the springs to which allows the GMC Topkick SuperSprings to activate when needed. If needed you can level or lift from side-to-side or front-to-rear with the shackles muti-hole settings.
Never load any vehicle beyond the manufactures gross vehicle weight rating (GVWR).
