FAQ
What vehicles do these control arms fit?
They fit 2005 to 2014 Ford Mustang. See the vehicle applications list above and match your year.
What makes boxed control arms better than the factory arms?
The arms are built from tubular steel and fully boxed, which adds strength and rigidity over the stamped factory arms and reduces flex under load for better traction and rear suspension control.
Why polyurethane bushings?
Polyurethane bushings are firmer than factory rubber, so they reduce deflection and keep the rear suspension located for more consistent handling and traction.
What is the difference between part number 1034-R and 1034-B?
Part number 1034-R is finished in red powder coat and 1034-B is finished in black powder coat. The control arms are otherwise identical.
