QA1 2-1/2in ID High Travel Spring - 12in Length x 600lbs/in - Silver Powder Coated

This QA1 high travel spring is made from a specially designed chrome silicon alloy wire. This allows for fewer coils and a smaller wire diameter, resulting in a lighter spring with increased travel due to the larger distance between the coils. These lighter springs help reduce unsprung weight, allowing your suspension to react faster and optimize performance. The high-grade material, combined with careful heat-treating and post-processing, offers greatly improved fatigue life. The coil design means these springs can be compressed to coil-bind without affecting their spring rate or free height. This particular spring measures 12 inches long with a 600 lb/in spring rate and a 2-1/2 inch inner diameter.

The springs are finished with a silver powder coat and are ground at both ends for straight, consistent, and accurate operation. QA1 proudly manufactures these springs in the USA, and they are lifetime guaranteed to remain within 2% of their original free height and rate under normal operating conditions. This makes them a solid option for applications where maximizing suspension travel and performance is key.
