QA1 Rectangular Rear Control Arms

Upgrade your 1979-2004 Mustang's handling by adding these QA1 rectangular rear control arms. These box-style rear control arms use polyurethane bushings on both ends which keeps the tires planted firmly on the ground for improved traction and a more predictable, better handling ride.

High Quality Construction

These QA1 Rectangular Rear Control Arms are made from 0.120" wall cold rolled steel tubing, which offers increased strength over other designs, but also has the added advantage of lighter weight, and are made right here in the USA. 

  • If these control arms will be installed on an early model Fox Body Mustang with the small rear sway bar, you must transfer over the factory sway bar bracket and attach it to the bracket on the new lower controls or upgrade to a larger sway bar.
