Product Description

The QA1 12HT170 is a high-travel coil-over spring engineered for universal application in custom suspension builds and performance vehicles. With a 12" free length and a 170 lb/in spring rate, it offers a balanced combination of support and comfort across street, drag, and off-road configurations. Designed to fit most coil-over systems with a 2.5" inside diameter, this spring allows greater travel before coil-bind and contributes to improved suspension response and control.

Constructed from chrome silicon alloy steel and finished in a silver powder-coated surface, the 12HT170 spring provides durability and corrosion resistance for long service life. Precision ground ends ensure consistent performance and fitment, and QA1's lifetime guarantee means the spring will retain its height and rate within 2 % under normal use. Always verify that your suspension hardware and coil-over geometry are compatible before installation to achieve optimal results.
