Neither, RPM is the best in the business hands down. You don't have to give them much of a reason to replace an axle, they'll do it for the hell of it. No I'm not kidding! They wanted to replace mine cause when I ordered some other stuff they wanted to know how their other equipment was doing on my banshee. I said my axle was a little hard to get through the carrier other than that everythings fine. They said sometimes the chrome is thicker than others and said they would send me out another axle so I wouldn't have that problem next time. I was like wtf not use to that kind of customer service. RPM doesn't play when it comes to customer service, that's why I use everything they sell.
