Product Details
Arnott’s Coil Strut Assembly line is built as a complete passive suspension solution for vehicles originally equipped with air or electronic suspension systems. The SK-3393 uses a twin-tube internal construction, hydraulic damping, and a progressive spring rate to provide controlled front-end response on the Cadillac XTS.

This part number, SK-3393, is a direct fit for 2013-2019 Cadillac XTS front applications listed as passive replacement for Magneride.
This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
