Perrin rear end links for the WRX and STI 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 WRX, STI, and 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. Rear end links utilize innovative polyurethane spacers, which makes them perform with the rigidity and positive feel of a spherical-joint end link but with some of the softness for day-to-day driving of polyurethane-bushed end links, making them truly the best of both worlds.
