Product Details

This Mevotech lateral arm is engineered for the rear left upper suspension position on 2020-2025 Ford Explorer and 2020-2025 Lincoln Aviator. The CMS401290 part number is also referenced as an OE-style replacement for the same application, and it cross-references Monroe Shocks & Struts 172286 for related fitment needs.

What It Helps Fix

  • Rear suspension looseness or play
  • Clunking or knocking from the rear upper suspension area
