Time will tell! Aren't they the 45RFE? Oh wait, they call it the 545RFE. I'm not a big fan of that one, but they do seem to be holding up better than the 42, 44, & 46RE's. I've only had to rebuild a couple of 45RFE's so far. I'm just not exactly happ about Dodge right now. It's been a long week, and I'm still "walking", almost ready to get the bike back out, and put some snow tires on it.
