I'm looking at purchasing an aluminum axle for my hill racer. It's made out of 7075 T-6 aircraft. Glamis has some bad whoops. Any comments?

 

Aluminium is soft. For such a stressed part, I don't get what advantage you get...to match steel resistance, it's gonna be HUGE (and almost as heavy). Maybe titanium is good, but for an axle, I'd stay traditional and get a steel composite one...like the X33 or similar...just my 2cents, I might be wrong.

 

I would agree with Zorro. For just about anything except drag racing, aluminium would be way too soft (even aircraft grade aluminium.)

 

I don't dune. I just race up the hill. Thanks for your replies. I'm hoping to here from someone who has actually run an aluminum axle.

 

It may sound weird, but the aluminum axels are very strong. Jimmy Elza (GNC PRO rider) has used them for years now, and if he can't break em, you cant't! The bad part about the alum. axels are the price,,but if you need the lighter weight of a alum. axel,, go for it! good luck [img]i/expressions/face-icon-small-smile.gif[/img]

 

You've got to be kidding. Not even I would use aluminum for GNCC. I know all AMA events have outlawed aluminum axles and TT racing is about to phase them out. I just figured that I wasn't riding as hard as these racers being that I'm a hill shooter. It's just the whoops that I'm worried about. Thanks for the info.

 

aluminum axels were made legal for this years GNC racing,quads only, not bikes

 

Any idea who makes his axle? I know Lonestar makes aluminum axles, but they warned me against runing one at the dunes. Theres are extra thick too. Maybe I'll call Nac's and see what's up with the aluminum axles.

 

well dang,,LSR is the only maker of an aluminum axel that i know of. that dont mean there isn't others out there. curious,why did LSR say no dunes on one?

 

Rad Manufacturing makes them too. There's are definately week. I talked to Nac's today and the aluminum axles are used for TT only. Lonestar said their axle would break through the whoops at the bottom of Oldsmobile.
Some guys can get away with it with their super light drag chassis. My bike is still at 340lbs.
