Swingarm dimensions

[2003LimitedBanshee]

Anybody have off hand the rectangular tubing dimensions on a stock swinger. I took a quick measurement and it looks like it should be 1 1/2" x 2" rectangular tubing. Anyone know the stock thickness? I just got my carrier "tube" and front pivot from JJ&A and I want to pickup some rectangular chromoly for doing up the main section of the swingarm. But I want to make sure I get the right size and wall thickness. I measured the stock swingarm at right about 20" from center of front pivot to center of stock carrier. Sound right?

 

I know this should really probably go in suspension, but I know that far less people actually go to that section of the forums.

 

Thanks! - Brian

 

EDIT: I was trying to get these measurements while the swinger was on the bike, so that's why I want to verify my center to center measurements etc.

I am doing the exact same thing, my parts will be in from jjanda tomorrow, I am going to use .120 wall x 1 3/8 round chromoly tubing. You will be alright using .095 wall if you go with the rectangular tubing. Chromoly is some tough shit.

So my local steel distributor, who has been in the area for quite some time (i.e. reputable) informed me that "you can't get chromoly in rectangular". But, they did have a stick of 2"x 1 1/2" with .120" wall mild steel. So, for now I suppose I'll just go with that. The .120" wall should give me enough strength and I can't imagine that I'm adding a ton of weight instead of using chromoly. Next challenge to tackle is building a jig. I'm envisioning a 1" plate with machined "towers" fish-mouthed on one end to hold the pivot and the carrier tub and turned on the other end that will fit into drilled holes on the plate. Then with the holes I can adjust the position of the towers to accomodate +2, +4, +6 etc.
