So today I disassemble the the prebuilt part of the shocks and found out the culprit to this was the x ring. Somehow the x rings on my 3 shocks looked like it was not cleanly round cut, there were burrs left over especially at the edges. I tried to cut those burrs but it was difficult to get it perfect. I m wondering are there any x ring or o ring (from other brand) that can fit nicely into our shocks.
