Tuff Country replacement leaf springs are the superior choice when choosing a positive arch leaf spring. All springs are tapered, snub rolled and pre-set for the most comfortable ride available in a lifted positive arch leaf spring. To reduce squeaking and improve ride characteristics, teflon inserts are also used between each leaf.
