Detailed Description
Arnott AS-5145 is engineered as a rear air suspension strut replacement for the Tesla Model X, 2016-2019, on vehicles without active damping. It combines an air spring and shock absorber into one assembly to restore rear suspension function with a direct-fit design. The unit uses a linear spring rate, gas-charged construction, and a hydraulic internal damper to support stable rear ride performance.
This rear air strut is built with a rubber air bladder, bearing plate, upper mounting isolator, lower mounting isolator, and protective boot to help protect internal components from road debris. Arnott AS-5145 also cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
Common Problems This Part Addresses
