Great value at literally 1/10th the price my local Lexus dealer offered me to replace the originals. Very easy to install by snapping sockets on each end of the top and bottom ball nozzles. This can be done using a simple screwdriver to pry the upright bushings at each end out of the ball they snap into. New ones can be created manually. For five minutes each. There are several videos on YouTube that demonstrate removing the original and reinstalling replacement racks. Highly recommended.
