I've been using them on my Tacoma for four or five months now. They are high quality and work really well . I was using the bike mounts that Toyota sells for the Tacoma rack system, but wasn't happy with those at all. The clutch sd is WAY better. No comparison.
My only advice - when installing the clutch sd, make sure you use some thread lock on the bolts. Otherwise, they will loosen. Haven't had to touch them since I did that.
