Perrin front end links for the Legacy GT feature solid aluminum construction and PTFE teflon-lined spherical bearings for the ultimate in strength and sway bar response. The spherical bearings allow for a multitude of dramatic angles while constantly maintaining a solid connection between the sway bar and the end link; making for performance you can feel. The bearings in the Perrin Legacy GT end links are pressed in using a unique 'swedge technique' which makes for a permanent installation of the spherical joint and seals them from debris and dust.
