Up FS is a CHE rear axle brace part # CHE9L for S197 05-14 Mustang (all models and 2011-14 V6 cars except convertibles) with 8.8 solid rear axle suspension. This brace bolts to your rear axle to strengthen it and prevent flexing of the housing and the axle tubes. This brace is powdercoated red for a nice appearance underneath the car. Comes complete with instructions, all parts, fasteners and templates for a trouble free install. Keep your 8.8 axle strong and prevent flex by adding this item to your car to help plant that hp/torque you have to the ground. Keeping the axle from flexing helps to reduce diff noise (especially if you have a gear done). This video shows how it looks installed on your car (not my car): Part is like new, installed on my 2013 GT500 for 2 months last year before I removed it when I sold the car.
