The QA1 Proma Star Series Double Adjustable Coil-Over Shock Absorber is engineered for high-performance vehicle suspension upgrades, offering a versatile solution for custom chassis builds and applications where direct-fit options are unavailable. With a compressed height of 10.125 inches and an extended height of 14 inches, this shock provides a broad range of ride height adjustments to help achieve your desired stance. Constructed with high-quality aluminum and featuring bearing mounts at both ends, it minimizes deflection and accommodates misalignment for enhanced durability and performance.
Designed for both street and track use, the Proma Star coil-over offers independent tuning of compression and rebound damping, allowing precise control over ride quality and handling characteristics. The shock is available with single- or double-adjustable valving, enabling drivers to fine-tune their suspension for optimal comfort, grip, and stability. The double-adjustable option is especially suited for track enthusiasts or those requiring detailed suspension adjustments, while the single-adjustable version provides quick, easy ride comfort modifications on street cars.
Installation is straightforward with various mounting configurations, including options for poly bushings with ½-inch and 5/8-inch sleeves to reduce NVH or bearing mounts for better alignment and reduced deflection. The included hardware kit allows for quick ride height adjustments—simply select the appropriate spring rate and length, then fine-tune your stance. QA1’s shocks are manufactured in the USA and dyno tested to ensure consistent quality and performance, backed by a limited lifetime warranty. Register your shocks at QA1.net/warranty before installation to activate coverage.
Ensure your vehicle’s suspension travel accommodates the shock's range to prevent overextending or bottoming out. Optional spanner wrenches and thrust bearings are available to facilitate ride height adjustments, ensuring a tailored fit for your specific setup. These shocks are an excellent choice for performance-minded drivers seeking customizable suspension tuning with reliable quality and industry-leading support.
