Tubular Steel Construction. QA1 Rear Upper Control Arms are constructed from 1-1/4" diameter, 0.120" wall steel tubing for light weight and superior strength. Graphite impregnated polyurethane differential bushings are included to replace the soft stock OE rubber bushings.
On Car Adjustable. The QA1 Rear Upper Control Arms are designed to be adjusted without removing the arms from the car. Simply loosen the jam nuts and set the pinion angle as desired for improved traction and better handling.
