McMaster lists 6061 box tube so I guess it does exist. Have you had any failure issues with your 7075 axles? I have considered 7075 axles for weight but have always chickened out and gone with steel. What diameter have you used? Last year we went with the IFI traction wheels with 3/8" ID bearings and thus 3/8" G8 bolts for dead axles. Do you think 3/8" 7075 dead axles hold up in competition?
