Recently, ride comfort has been sort after even from low-down spring users. Users are not only concerned about ride comfort, but also if any abnormal sounds coming from their springs. Many ask, �gWhere does the irregular noise originate from in the low-down spring?�h The most common reason is the metallic noise created at the point when the springs are compressed and stick together.

Most low-down springs theses days are variable rate types, and even by dropping the vehicle ride height, there will be no unwanted play from the springs. If you have a look at this variable rate spring (Photo 1), you can see that the top and bottom part of the spring has been wound differently. The pitch is narrower on the top part and wider in the lower part.

So where does the sound from the spring come from? If you look at (Photo 1), the arrow points to the part where the narrow pitch changes to a wider pitch, and also where the sound comes from.

The narrow pitch part of the variable rate spring will stick together when the vehicle is jacked down. While driving, this will stay stuck together and will not make any sound. TEIN developed the Silencer Rubber to reduce any unpleasant noise caused from the spring and can be purchased separately. Just by placing the Silencer Rubber at the point shown in (Photo 2) will reduce any unpleasant sound.

Having a Silencer Rubber at the end which comes in contact with the spring seat, as shown by the lower arrow in (Photo 2), is also very effective.

The low-down springs like in (Photo 3) vary according to the vehicle model. The silencer rubber also accommodates this, and comes in S/ M/ L to fit the customer�fs spring size. Special adhesive has been applied to the interior of the silencer rubber, so after installation, there is no concern about it coming off for a long time.
