MIA's Description

This product is a rear hitch crossmember designed to address premature and excessive rust issues in Toyota 4Runner, FJ Cruiser, and Lexus GX470 vehicles. It is made from heavy-duty 11 gauge steel and is CNC bent for precise fitment. The design focuses on fitment, ease of installation, and OE compatibility. Welding is required for installation, and holes may need to be drilled if installing a hitch. The crossmember ships with an oil protective coating and is backed by a Lifetime Warranty.
