This small kit includes our heim-jointed sway bar end links, our driveshaft spacer and out 4wd transmission mount to complete any of the current titan bracket lift kits (Procomp, CST, Rancho 4", Roungh Country 4 or 6", or Fabtech). The factory components typically fail in the first 6-12 months after installing the lift. We have offered all these parts separately for some time, but now you can buy them in one package and save some money.
