I did a search on JP racing, seems they are now Lonestar, what I need to know is/was the jp racing axle/swingarm good stuff, is it basically the same as the lonestar is now. Is the stuff worth buying?

 

It was good stuff but the problem is JP Racing hasn't existed (as that name) for about 10 years. If you could even find something from JP Racing, it's going to be outdated and probably trashed. But if it isn't and a good price, I would go for it.
