Return PolicyAvailable in 7", 9", 10", 12", 14" and 16" lengths, QA1 offers an assortment of high travel springs with a silver powder coated finish. Made in the USA, these 2.5" I.D. high travel springs are manufactured from specially designed high-tensile, chrome silicon alloy spring wire, which allows them to have fewer coils and a smaller wire diameter. As a result, these springs 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.
These new high travel springs are silver powder coated and ground at both ends for straight, consistent and accurate operations. In addition, all QA1 springs are lifetime guaranteed to remain within 2% of the original free height and rate under normal operating conditions.

Customers laud the QA1 coilover springs for their quality and performance, particularly in auto-crossing contexts where competitors' springs often bind. The product delivers on usability by fitting seamlessly into setups needing spring rate modifications in rear coilover. The material quality has been proven in demanding situations such as installations in a variety of vehicles, from a '55 T-Bird to a Corvette C-4 IRS suspension. Users recommend the QA1 springs as a reliable and high-performing alternative to other kits.

was running some 170lb spring that came with coil over kit from upr. Coil bind was happing all over the place while autoxing. The effect were not of good sorts. Have Not race tested these springs yet, but everything feels nice even on public roads before an alignment and height adjustment.
