No tey are not all created equal. Many are the same design, but there are two VERY nice and BETTER products available than most. I run a firewall stabilizer, quick release clutch quadrant and cable from Pro Motion. It offers a lot of unique features, the biggest of whihc is the ramp rate is different than all others resulting in quicker clutch disengament and more air gap which is something that was a real problem for me as I needed more than all others could get me and this led to missed shifts at high rpms. Also one of our very own members here has his own design which seems to have a lot of cool features as well. Check out http://www.fioreperformanceparts.com/ and check out his micro click adjuster.
