KW Tesla top mount and progressive spring

The KW Upgrade support bearing and progressive spring kit suits only Tesla Model 3 and Tesla Model Y KW and ST coilovers with linear racing springs. The kit includes two progressive springs, two spring perches, two spring mounts and as a replacement for the series dome bearing, the two new KW support bearings. Our KW support bearing differs from the series dome bearing from Tesla by a different rubber-metal element. Our KW rubber mount reacts much more sensitively to impulses and features a progressive force increase. In contrast, the Tesla series dome bearing has a linear design for the entire force increase. The KW Upgrade Kit support bearing and suspension springs for Tesla Model 3 and Tesla Model Y are only suitable for installation for our KW V3, KW V3 Leveling and ST XA coilovers, which have linear racing springs.
