Proforged sleeved polygraphite LCA bushings!

I do know that I recently took apart two of the original OEM rubber LCA bushings in order to utilize the inner and outer steel sleeves to modify polygraphite or other bushings. Here is what I noticed. It doesn’t seem that the rubber is bonded to the inner or outer steel sleeve. Instead the rubber is compressed and stretched down to create the tight fit in the bushings. The steel sleeves were clean and no residue or bonding was present after I pressed out the bushings. It appeared that the rubber bushing is much fatter and shorter in height when taken out. The pressed in fit within the OEM bushings seem to stretch it in length and thin it out significantly when put between the two metal sleeves. I now have much better understanding of how these LCA bushings work and the functional differences between OEM rubber, proforged, polygraphite, or Delrin. The polygraphite, or steel sleeved polygraphites made by proforged are made to be able to spin/move on the inner steel sleeves as the LCA moves. Contrary to the OEM rubber which doesn’t spin and the flex and twist of the rubber allows for the proper functioning of the LCA. I again want to thank everyone on this site for chiming in and sharing their expertise. I wouldn’t be able to tackle all the jobs I’ve attempted without the support from the experts on here.
