i do not know the measurements off hand. i would have to make up another set to tell you and if i'm making up another set i might as well make up 10 sets. they might not work, i don't know. there is deffinatly more friction that the stock pivots, i don't know if that will wear in or if i have to change my design or if it doesn't matter. couldnt tell ya. the little friction doesn't bother me but it might bother the next guy. its hard enough making something and selling it when it works muchless when you have no idea if its gonna last for more than 5 minutes. i made some other parts and some people were not happy about the milling marks in them, then i walk out in the garage and the polished rims on the car have the same marks all over them. you see what i'm saying?

I bet these would wear quickly...for the average rider they may last a while though...

Ive been using UHMW plastic for everything from shock bushings to chain sliders and they hold up way better than the crap plastic the stock a arm bushing were made of. I would make the side washers full width instead of the half width of the factory sleeve. You just have to get the surface loads right .

I'm sure anybody who races knows that the stock design is garbage. I love the simplicity of the bushings haha. I would buy a few for our race quads for sure. Either way the bushings have to be cheaper than the stock bearing design.

My son ran a whole season with his Moto, they did need replacing, but the damage was from the design of the swingarm. Bad design I would say is the opening inside the tube the bearings is in,

I just finished rebuilding a blown rear axle bearing set in my speed. The swingarm pivots I installed many years ago had a needle bearing with a lip seal on each end and the open hole design swingarm. I am happy to report that they had no water intrusion and no wear. I installed the wide spacers to the inside and presssed the bearing in so it wasnt centered over the hole like the stocker. More towards the outside of the swingarm. I didnt even run an inner seal. Its to bad they didnt fix the swingarm till the last few months with the sleeve in them.
