Springs with 1 or 2 retracted ends

This widely used form for suspension spring coils is characterized by the reduced diameter of the ends, either one or both ends being smaller than the spring body. The development of weight-optimized Mubea suspension coil springs is always performed based on our proprietary design and FEM programs. Later, the designs are checked for mass production capacity by our own prototype department and in-house test lab. Our customers in the independent aftermarket benefit from this long-term development process, offering the highest level of safety and quality.
