This Nolathane Sway Bar Bush Kit replaces the original equipment unit on Hyundai Kona models built from 2020 to 2022. All hardware, washers and a grease sachet are included where required. Ball studs are heat treated and fitted with a dust boot to keep grit out of the bearing surface. The Polyurethane component is dimensionally matched to the original part, so steering feel and alignment settings are unchanged. We recommend fitting by a qualified technician and following the manufacturer's torque specifications. Every unit is supplied new with a 12 Months warranty against manufacturing defect.
