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
that react faster and are lighter, reducing critical unsprung weight. All springs are ground square at both ends for straight-
ness, 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.
