QA1 PROMA STAR SINGLE ADJUSTABLE COIL-OVER SHOCKS DS401 Product Description:

Overview

QA1’s Proma Star Coil-Overs help you gain the benefits of coil-over shocks on a huge range of vehicles. Building a custom chassis or suspension components? Can’t find direct fit options for your vehicle? These are for you. Available with 3” to 9” of stroke and single or double adjustable valving, QA1 shocks instantly upgrade ride quality and performance. The shock and included hardware kit provide quick and easy ride height adjustability to get the perfect stance. Just add a 2.5” spring of the appropriate length and spring rate to get rolling.

Choose from single  or double adjustable valving to dial in ride comfort and performance. Single adjustable shocks work great for street cars, softening or stiffening the overall ride with one knob.

Double adjustable shocks are ideal for cars that see consistent track time or drivers who want to fine tune their ride quality. Independent compression and rebound tuning make this shock equally at home on the street, drag strip and road course.

Choose from multiple mounting configurations. The poly bushing option includes ½” and 5/8” sleeves, while helping to reduce NVH. Bearing mount shocks minimize deflection and work well if your mounts require misalignment. Other mounting styles are available (sold separately) for T-Bar and stud-mount applications. Extended eyelets can also be used.

All QA1 Proma Star shocks are made in the USA and dyno tested to ensure performance and quality. They are eligible for an industry-leading Limited Lifetime Warranty. Register shocks at QA1.net/warranty before installation.

Kit includes:

  • 1 Coil-over shock.
  • Hardware.

Fitment Note: Insure your shock will have an adequate amount of travel to avoid overextending or bottoming out the shock. Available spanner wrenches and thrust bearings increase ease of ride height adjustment. If using a stock spring pocket, ensure you can achieve your desired ride height while incorporating enough shock travel
