OSSA suspension linkage

On my original 2014 Explorer (sold a couple years ago) I broke the suspension linkage a couple of times. I bought some Titanium ones and they were great (with lube fittings). But the company no longer makes them. I suspect they didn’t sell very many at all. 

Since I like learning things and have been working on Fusion (3D CAD) I have been designing a new linkage. I am basing off 2015 links (larger main link) but going to change to needle bearings in the middle of the link, with lubrication passages. The other ones would be a lot more difficult to change from the bushings, but I can still put lube passages. 

 I have 3D printed the parts so I can test fit and make sure I got dimensions correct.  Measuring/comparing to stock- I think I’m right on. The Ti ones I bought all the fittings to grease, I used to do so after every ride since there were no seals at all and the new grease would help push out contaminates. The needle berarings I found do have seals, so I will see about not doing it nearly as much if they really are effective. 

I can get them made out of any material I want- just a matter of cost. Once I have verified all is how I want, I will send the CAD files to a couple manufactures and get prices. I expect a good steel would be a LOT cheaper than titanium, and while heavier, most still quite a lot stronger than the stock aluminium parts. 

 It has been a fun project so far- I will keep posting as it moves along.
