This Whiteline Sway Bar Bush Kit replaces the original equipment unit on Mercedes-Benz C-Class and Mercedes-Benz GLC models built from 2018 to 2022. All hardware, washers and a grease sachet are included where required. Expect a small increase in road noise compared with the factory rubber item; this is normal for a firmer compound. A wheel alignment is recommended after fitting any steering or suspension component. Ball studs are heat treated and fitted with a dust boot to keep grit out of the bearing surface. Every unit is supplied new with a 36 Months warranty against manufacturing defect.
