BMR's upper control arm mount is a direct replacement for the OE piece
and requires no drilling or welding to install. The last generation Fox
body Mustangs had upper control arm mounts incorporated into the frame.
They also had two upper control arms sharing the load but drag racers
were continually ripping the mounts off of the frame when racing. The
solution for those cars was to weld reinforcement plates onto the
frame. This new Mustang platform only has one upper control arm and the
mount is bolted into place. Our upper mount is made from heavy duty
1/4" plate and can be either bolted or welded into place. Additionally
it has dual control arm mounting points for changing instant center.
This
specific part number is intended for 2011-14 Mustangs that utilize the
larger 18mm mounting bolt and cross-bolt.
