Review on Energy Suspension 2 2101G SPRING BUSHING by Joseph Stone

I was now able to fit both the red Prothane bushings and the black Energy Suspension bushings on the same car a year apart (the bushings didn't fail - the Jeep was rolling at high speed and I had to redo the suspension). The black sockets could be mounted with much less effort. So far they've performed just as well, if not a little quieter.
