The original spring perch and sway bar mount on the 2000 to 2004 Ford Super Duty F250, F350 and Excursion 4WD trucks tends to fill up with water and can rust. This problem is made even worse in parts of the country that salt the roads during the winter. The only solution Ford offers is to replace the entire housing at great expense. Autofab solves this high dollar replacement cost with this high quality, fabricated replacement Super Duty spring perch, sway bar, and track bar mount. This repair part requires removal, grinding, and welding by a qualified technician for installation. This part does not fit early 1999 trucks.
