Tuff Country EZ-Ride leaf springs are tapered, snub-rolled, and preset for the most comfortable ride available in lifted, positive-arch leaf springs. PTFE inserts are also used to help with ride characteristics as well as to reduce squeaking. Heavy-duty applications are also available to help accommodate a winch or for heavy towing applications. Tuff Country is the originator of the 3 and 4-leaf EZ-Ride leaf springs. Tuff Country's research has proven that using thicker steel per leaf and fewer leafs results in a much smoother ride than using the standard thinner steel and more leafs.

Dinan Performance spring sets provide greater control over body roll via carefully calibrated spring rates. Plus, they lower your vehicle for improved suspension geometry and a more aggressive stance. Dinan springs are CNC-wound with high-tensile chrome silicon wire and are shot-peened for stress relief to last the life of your car. The increase in stiffness of the springs will reduce the rear suspension compression under acceleration, as well as the front suspension compression (or dive) under braking, giving your car a more controlled feel. The performance springs will also provide a noticeable improvement in grip, for high-speed driving situations that will inspire confidence in your car's capabilities. Use these performance spring sets in tandem with their supplemental ride quality and handling kits for the ultimate Dinan suspension experience.
