2-1/2" ID Coil-Over Springs
All QA1 coil-over springs are manufactured from quality, cold wound chrome silicone steel which has undergone though heat treating and
shot peening. Choose from traditional chrome-plated, or High Travel silver powder coated springs. High-Travel springs feature a smaller wire
diameter and have fewer coils, resulting in springs that have increased travel, but react faster and are lighter, reducing critical unsprung
weight. All springs are ground square at both ends for straightness, and are marked with the free length and spring rate. Covered by a
limited lifetime warranty to remain within 2% of the original free height and rate.
