Our KINETIK sway-bar hardware kit includes the delrin pivot bushings that fits into 2? x .120w tubing for mounting, CNC machined anodized aluminum retainer end caps, 4130 chromoly heim tabs for the end of the sway-bar, delrin pivot spacers and all the Grade 8 hardware needed to complete the assembly. This kit works with all our KINETIK sway-bar arms and takes out the guess work and time rounding up parts.
