c-clip eliminators on the street
#2
They use a sealed bearing usually, which means they can heat up fairly quick. I have knwon people to use them on the street w/o problems, but that isnt what they are designd for. On a daily driver that saw highway time you are taking a chance.

no problems here... I'm the second owner of this 12 bolt, it's been in a car (mine or the previous owner's) for a few years now and its never had a problem with c-clip eliminators. I drive my car 2-3 times a week, at least once a week through stop & go traffic, go to the drag races a couple times a month... previous owner had it on his 9 second drag car.
