the materials are going to be 1018 steel for the sleeves and 7075 aluminum for the spacers. price is for 1 car, both sides. you get: 1 pair of sleeves, 1 pair of snap rings, 4 spacers and shipping in the US. you source your own bearings and sealing implements, and either weld or retaining compound them into the knuckle.
here is a rendering
and as a reminder to everyone the bearing dimensions you need to adhere to can be found on this page:
2 of these were $84 to my door from motion industries
Item # AIB-10, AIB Series Spherical Bearings On Aurora Bearing Co.
and here are the cheap alternatives from qa1 at summit

this is the only other option besides ISC that i know of at the moment. and please understand i have no experience with their products and can only assume at their price point that they arnt auroras or equivelent. so to say that as fact would be conjecture.

if you are talking about the rear outers (knuckle side), i think you have that backwards. the lowers dont require misalignment, they just need to pivot, so you would want the delrin in the lower position. the uppers need be able to misalign, so thats where youd want the spherical.

Now I understand what you're offering. Thanks

Do you mind replacing the QA1s 2-3 times a season vs the auoras lasting 1-2 seasons. Theres really no point to going through all the expense of putting sphericals in the car if you're just going to run ones that are so sloppy that you get more play in the joint than with the rubber bushing.

*edit*
What degree of misalignment will you all be going with, if any?

They're so cheap why don't you just give them a try? The whole point of the sleeves is to be able to service the bearing. Worst case scenario you get a couple of events out of them for $30. I don't think theyll be as bad as leafy makes them out to be. They won't last as long as auroras, but I think you'll get more than 2 events out of them.

here is evidence that there is significant longitudinal forces on the upper bushings.
some grommets i had in a harbor freight assortment worked well as seals. ill need a different solution when/if i upgrade to larger spacers as these were a very tight fit.
i had to cut one at a taper so it would seat in the sleeve
grease
clamped and sitting on jack stands over night
