Detailed Description

FCS 355045 is a rear suspension strut engineered for specific late-model GM SUVs, including the Chevrolet Tahoe, GMC Yukon, and GMC Yukon XL. Fitment is limited to the rear position and depends on the suspension package: 2021-2022 Chevrolet Tahoe rear applications exclude air suspension, while 2021-2022 GMC Yukon and Yukon XL rear applications require electronic suspension and exclude front and rear air suspension. For 2023-2026 GMC Yukon and Yukon XL rear applications, this part excludes electronic suspension and front and rear air suspension.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. If you are searching for FCS 355045 rear strut replacement for GMC Yukon or Chevrolet Tahoe, verify the suspension system before ordering to confirm the correct configuration.

What It Helps Address
