Motorgeek, we have 2" of solid aluminum inserted into each opening of the cut stock tubes which will get anchor welded on three sides on each end both tubes. Then going to overlap it all with plating for added strength. It will be welded in a jig by a guy that's been welding aluminum for 35 years and been instructing a welding class for 20 years so I know the welds will be done right and hold. My buddy that had the pieces machined for me is an engineer and every simulation he's ran says it will hold up to a ton of abuse. If it does break I can always have it rewelded plus I still have my stock polished swingarm that will be shelved if need be.
