Fully agree with Ivormog who well summurizes the SSL advantages.

The best improvement made on my 2005 PLUS 4. A suspension which works on the right way.

On mechanical aspect, less stress on the chassis and the radiator. Installed by myself without difficulties, but if you have to change the kingpins and the bushes you must have some mechanical know-how and a reamer.
