Detailed Description

Mevotech CMS401289 is a suspension lateral arm engineered for the rear lower rearward location on 2020-2022 Ford Explorer and 2020-2022 Lincoln Aviator models. The steel arm uses bushing ends instead of a ball joint, and the rubber bushing material helps maintain the original suspension connection style for this application.
