Located in Hagen, Germany Vogtland GmbH has been a family run operation since the beginning.  They operate 2 plants in Germany, and their newest operation Vogtland NA is located in Temecula, CA.

All Vogtland springs are made using a computer controlled Wafios coil winding machine.  The springs are cold wound to assure minimal changes to the properties of the metal.  See a video of the winding process here.

After the winding process the raw springs are heated treated in a large oven.  The heat treating relieves the built up stress within the material caused from the coil winding process.  Springs must be heat treated immediately to prevent damaging the material, and causing it to fatigue.

Once the heat treating process has completed, the springs are left to cool so they can be handled.  Springs that require their end be ground flat have that step done once they have cooled sufficiently to handle. 

Different methods are used depending on the spring size and material properties.  Larger springs are clamped and pressed against grinding wheels.  While smaller springs are placed on a spinning table with abrasive material above and/or below to flatten the surfaces.  

Once the grinding process is completed, the springs undergo a shot-peening process.

Shot peening is done in a large enclosure where the springs are fired upon by very small balls of metal.  The shot peening process relieves the stress within the spring, and also removes any minor surface imperfections.  This step is critical to the longevity of the spring, and should be done thoroughly to all parts of the spring coil.   

Following the shot peening, the springs undergo a setting procedure.  Block setting compresses the spring until all the coils touch.  This step  assures that the spring will not sag, or otherwise deteriorate over the life of the spring.  Vogtland springs are block set 3 times, where many inferior companies set only once.  It's a critical process to make certain that the springs will last.

Vogtland springs undergo a strict testing procedure to make sure each spring will withstand a lifetime of use.  Springs are carefully measured for length and spring rate.
 
At this stage springs can fully be measured and tested for spring rate, spring deflection, and length.  Springs that are ground flat are also carefully measured to make certain that the ends of the springs are parallel to one other.  Vogtland uses very high precision optical measuring equipment along with computer aided graphics to make sure all springs are perfect before being shipped.

Once Vogtland springs have been tested they are carefully phosphate coated for protection against corrosion, then powder coated for a beautiful long lasting finish.  The springs are labeled, boxed and warehoused in various locations throughout Germany for quick distribution.
 
Vogtland NA maintains their own enormous supply on all lower springs, suspension kits, and coilover systems for all US distribution.  You can be assured that all US customers will receive spring in a quick and timely manner. 

With Vogtland's long history of spring making, and some of the best technology in the world, you can rest assured that all Vogtland products will deliver the perfect combination of driving performance with road comfort.
