Hi, I'm new to this forum. I bought a used 2007 Raptor 700 with ASR extended A-arms, I'm in the process of rebuilding the Raptor. It's been like 6 months since I took it apart, now that I'm putting it back together I noticed that the lower A-arms doesn't have an inner metal sleeve, just the Delron/plastic bushings. On the Internet I have seen some with the metal sleeve and others without it. Do you have some idea if I'm missing something?
