AST Suspension Lowering Springs

Please note there is currently a lead time of approx 1-2 weeks, but please contact us for a accurate lead time.

These springs are made of chrome – silicium material. After winding the springs, the material is heated in order to relax the metal. The springs are heated from 300 to 460 degrees Celsius depending on the spring thickness. Then the springs are sandblasted (shot peening) and a special coating is applied. We offer lifetime warranty on all AST Lowering Springs.
