QA1 15HTFB300 Details

  • These silver powder, high travel springs are made to fit with QA1's 4th Generation F-Body Pro Coil Systems.
  • With a 2.125" upper I.D. and 2.5" lower I.D.
  • Made in the USA, these high travel springs have fewer coils and a smaller wire diameter.
  • As a result, they are lighter and have increased travel due to the larger distance between the coils.
  • These lighter springs reduce unsprung weight and react faster, optimizing suspension performance.
  • In addition, this high-grade material, along with careful heat-treating and post-processing, allows for greatly improved fatigue life, and the coil design allows the springs to be compressed to coil-bind without affecting spring rate or free height.
  • All QA1 springs are manufactured using the highest quality materials for high strength, consistency and long life.
  • They are cold wound, heat treated and shot peened to ensure consistency, accuracy and durability.
  • All QA1 springs are ground at both ends to ensure straight, consistent and accurate operation.
  • They are either silver powder coated for excellent longevity, or are polished and chrome plated for the ultimate in appearance.
  • Lengths and rates are clearly marked for quick and easy identification.
  • All QA1 springs are lifetime guaranteed to remain within 2% of the original free height and rate under normal operating conditions.
