QA1 2-1/2in ID High Travel Spring - 14in Length x 250lbs/in - Silver Powder Coated

Starting with a 2-1/2 inch inner diameter and a 14-inch length, this QA1 high travel spring is built with a 250 lb/in spring rate. It’s constructed from a specially designed high-tensile chrome silicon alloy wire. This advanced material allows for fewer coils and a smaller wire diameter, which means the spring itself is lighter and has more travel because the coils are spaced further apart. Reducing unsprung weight helps your suspension react faster, optimizing overall performance.

The chrome silicon material, combined with careful heat-treating and shot peening processes, gives these springs improved fatigue life. The coil design is also made so the springs can be compressed all the way down to coil-bind without changing their spring rate or free height. QA1 finishes these springs with a silver powder coat and grinds both ends to ensure they operate straight and consistently. They are also clearly marked with their free length and spring rate for easy identification.

QA1 proudly makes these springs in the USA and backs them with a lifetime guarantee, ensuring they will remain within 2% of their original free height and rate under normal operating conditions.
