Swift springs review!!!!!

370Z JT

I think they are called spring silencers. It is a rubber tubing that goes in the middle coil and top coil of the front springs.

scroll down until you see the below text. It would make sense if this was the issue becuase the noise I am hearing definitely sounds like coil contact.


Silence Noisy Coils Use Whiteline's new spiral coil wrap to silence noisy progressive coil springs. Most new cars use coil spring insulators to reduce NVH resulting from coil bind or contact between "dead" or closed coils. Many aftermarket springs require a progressive design using "dead" coils to meet captive height design requirements. These can become noisy under certain loads making an add-on insulator very useful.

The spiral design lets you insulate the springs WHILE the coils are in the vehicle saving time and money. Each pack contains 1.5 metres of heavy duty plastic spiral wrap which is enough to do 2 springs.
