You must mean it rides stiffer than new? I love poly, I have it in every bushing and mount on the truck. The stiffness is negligible but the rubber dry rots fast in the desert heat. The best poly bushings are the ones impregnated with graphite. It "might" help with squeaking for those that don't maintain them with occasional silicon grease. If you really want a noticeable difference in the way she handles, consider the Jeep steering shaft swap. Like night and day. But, nice job and enjoy.I replaced my rear spring bushings this past weekend. The job went pretty well. The old bushings looked like they were original. These two were the last ones that I had to do. The trucks suspension has been redone front and back. With the new shocks and all the other work she rides better then New.
