The bracket kit allows the top shock absorber mountings to be located onto the brackets which are in turn mounted directly onto the chassis. This offers a more positive location (directs stress loading away from wheel arches & on to chassis) and improves handling. The brackets are designed to be used with shock absorber GDA4011 which is available in either standard or a variety of uprated specifications.
