I just got one that I ordered and I'm thoroughly unimpressed. Mostly because the adjustment part is no different than my stock one. I ASSumed it would be the type where you put a steel rod into a hole on the sprocket side to make your chain adjustment but its just like the stock one, only the stock one gives you a little more of a notch to grab than this thing does. The Lonestar one has the holes in it for adjustment but they're on backorder until mid-February. My other gripe is that every one pictured on their site has a grease zerk on the side that you can access pretty easily, this has a hole drilled there but its a blind hole and doesn't lead to anything. It has the other zerk that you can access by taking the cap off on the back of the arm. I'm contemplating sending this thing back and I wanted to warn anyone else who is considering one that it isn't an improvement.
You can see on the left that there is one step that is VERY shallow, there is another just like that but the pic is dark and you can see it. The ones next to the shallow ones are better on one side but not the other.
