   QA1 has street and race control arms for for 1979-2004 Mustangs, via Marken Performance, both using a tubular design and work with QA1 coil-over struts.  These lightweight tubular arms offer a 50% reduction in weight over stock control arms, improving handling and allowing the suspension to react quickly. 

   Street Control Arms have a factory replacement ball joint and polyurethane pivot bushings and are engineered for performance.

   The new race control arms use QA1’s exclusive X Series chromoly rod ends and are designed for drag racing, pro-touring and hard core street applications.  The race ones have been redesigned to include sway bar mounts for those who choose to run a sway bar.  The new race control arms also utilize QA1’s Low Friction Ball Joints, which give drivers a wide range of wheel alignment settings and reduce friction in the front suspension. Extremely strong and wear resistant, these low friction ball joints offer on-the-car adjustment and self-lubricating components. They are also available individually and in extended lengths.
