QA1 MG401-08750C Details

The QA1 Pro Coil System is a great option for anyone looking for fully adjustable ride height and valving control. Choose a spring rate and adjustability that fits your driving style, adjust the valving to match and you are on your way. These shocks also utilize a fully threaded body that allows you to adjust your ride height for the perfect stance or to finely tune the weight balance for superior handling.

Specially designed for QA1's Pro Coil Systems, the American-made lightweight high travel springs* have fewer coils and a smaller wire diameter, resulting in increased travel due to the larger distance between the coils. They reduce unsprung weight and react faster, optimizing suspension performance. Multiple spring rate options are also available and have been successfully tested in various applications, from casual street driving to hard core race applications.

Adjustable Pro Coil System Features:

  • MOD™ Series - independent compression and rebound double adjustable
  • Lightweight Billet Aluminum Coil-Over Shocks
  • High Travel Springs*

Additional MOD™ Series Features:

  • Features QuickTune™ technology - modular valve packs that allow for completely revalving the shock without having to remove it from the car!
    • Medium compression and rebound valve packs standard
    • Soft or firm compression and rebound valve packs also available
  • 24 click independent compression and rebound adjustment with low-speed bleed
  • Large solid piston (with blow-off valve) for improved driver feel and control with up to 1,600 lb. force
  • High-speed valving adjustment (coarse adjustment)-relates to shock operation during impact events, like hitting a pothole or curb
  • Low-speed valving (fine-tune adjustments)-adjusts ride quality and weight transfer on corner entry/exit; more bleed for softer feel and less bleed for stiffer feel
