QA1 2-1/2" ID High Travel Coilover Spring - 12" Length x 170 lbs/in (Silver)

Boost your vehicle's suspension capabilities with the QA1 High Travel Coilover Spring. This 12-inch spring features a 2-1/2 inch inner diameter and a robust 170 lbs/in spring rate, finished in a durable silver powder coat. Engineered and manufactured in the USA, QA1 employs high-tensile, chrome silicon alloy spring wire. This specialized material allows for a design with fewer coils and a smaller wire diameter, resulting in a lighter spring that provides increased suspension travel.

Performance Advantages:

  • Reduced Unsprung Mass: The lighter spring design contributes to lower unsprung weight, enhancing suspension responsiveness.
  • Extended Travel: The unique coil configuration offers greater suspension travel, improving ride comfort and handling precision.
  • Optimized Dynamics: Faster reaction times and increased travel translate to a significant improvement in overall suspension performance.
  • Superior Material Quality: High-grade materials, combined with meticulous heat-treating and post-processing, ensure greatly improved fatigue life.
  • Consistent Rate & Height: The intelligent coil design allows the spring to be compressed to coil-bind without altering its spring rate or free height.

This QA1 High Travel Spring is an ideal choice for drivers seeking enhanced control and a more dynamic driving experience. Its construction is built to withstand demanding conditions, making it suitable for performance street and track applications. Available in various lengths and rates to meet diverse automotive needs.
