QA1 Proma Star Double Adjustable Front Strut - Pair
When it comes to upgrading your 1979-1993 Fox Body Mustang's suspension, no one wants to settle for anything less than perfect; go with QA1 Proma Star double adjustable front struts. Whether you are looking to have a mild drag setup, have a comfortable street ride, or firm your ride up for autocross, QA1's struts have what you need. A major advantage of the Proma Star strut is its inverted cartridge design. Unlike conventional designs, its large diameter shaft resists side loading, ensuring smoother and more consistent performance during hard cornering and braking. 

QA1 Quality
High-performance DOM steel is used for superior strength. A lightweight threaded aluminum body allows height adjustment from stock to 2.0" lowered with the addition of a coilover conversion kit. QA1 double adjustable struts provide different adjustments with a single turn of a knob! Eighteen valving settings on one knob simultaneously adjust compression and rebound independently on the shock. Constructed in the USA, QA1 dyno tests and serializes each kit for superior quality control, along with being fully serviceable and rebuildable by any QA1 authorized service center. The adjustment knob has a durable red anodized finish, resists corrosion, and looks good in your engine bay. QA1 Proma Star struts are proudly made in Lakeville, Minnesota.

Adjustment notes
  • Pressing the adjustment knob DOWN will adjust the Compression valving of the strut. Pulling the adjustment knob UP will adjust the Rebound valving.
  • Out of box, the strut should be at zero compression and rebound setting, or both adjustments turned counterclockwise to stop. From the zero setting with the knob in the Compression position (pushed down), adjust clockwise to the desired setting. The Rebound setting will remain in the zero position.
  • To adjust Rebound, pull the knob up to the Rebound adjust position and adjust clockwise to the desired setting.
  • Either setting can now be adjusted up or down from the initial setting. When in doubt, turn the Compression to zero and then Rebound to zero and readjust.
