QA1 2-1/2" ID High Travel Coilover Spring - 12" Length x 150 lbs/in (Silver)

Enhance your vehicle's suspension performance with the QA1 High Travel Coilover Spring. This 12-inch long spring features a 2-1/2 inch inner diameter and a spring rate of 150 lbs/in, finished in a durable silver powder coat. Proudly made in the USA, QA1 utilizes specially designed high-tensile, chrome silicon alloy spring wire. This advanced material allows for fewer coils and a smaller wire diameter, resulting in a lighter spring that offers increased travel due to the larger distance between coils.

Key Benefits:

  • Reduced Unsprung Weight: The lighter spring design contributes to lower unsprung mass, allowing your suspension to react more quickly to road inputs.
  • Increased Travel: The unique coil design provides greater suspension travel, improving ride quality and handling.
  • Optimized Performance: Faster reaction times and improved travel lead to a noticeable enhancement in overall suspension performance.
  • Exceptional Durability: Manufactured with high-grade materials, carefully heat-treated and post-processed for significantly improved fatigue life.
  • Consistent Performance: The coil design ensures that the spring can be compressed to coil-bind without compromising its spring rate or free height.

This QA1 High Travel Spring is an excellent choice for performance enthusiasts seeking to optimize their vehicle's handling and responsiveness. Available in various lengths and spring rates to suit your specific needs.
