BMW coilover thrust bearing spring perch

BMW coilover thrust bearing spring perch is used as a rotating spring perch on coilover suspension. It is mounted between the spring and spring seat and helps the spring rotate more freely when the suspension works and when the wheels turn.

The rotating construction reduces twisting, tension and spring bind in the spring. This can provide smoother suspension movement, less load on the spring and top mount, and more stable function in drift, track day, motorsport and performance driving.

The product is especially relevant for cars with coilover suspension, stiffer springs, camber plates or motorsport setups, where the spring is exposed to high load and large movements. A coilover thrust bearing spring perch can help make the suspension movement freer and more precise, especially on the front axle.

The product is made from S355 structural steel and built with a thrust bearing. The surface is galvanised for better protection against corrosion and load.

Always check dimensions and compatibility with your coilover suspension before installation.
