EDIT: Maybe these? https://us.gktech.com/products/zn6-8...erical-bushing It says toe arm, but maybe it means the traction / trailing arm, based on the customer pictures.

The Cusco upper arms use a hardened rubber bushing (I'd rather a spherical but that's better than poly IMO).
The STI trailing arm is a nice simple piece with a good quality bearing. I use it and combined with the MCA traction mod it's a really nice upgrade. Cusco make a nice trailing arm if you want adjustability.
I think Cusco makes a pillowball for the trailing arm into hub position but I'm not 100% sure. They have them for most locations.
Going to more pillowball bushings can feel pretty good. It'll ask more of your dampers but it reduces bind in your suspension. They get a bad rap sometimes, but that's often because of poor quality bearings. In some cases, they can improve ride quality.
Anyway, I stay away from polyurethane in most cases and I'm careful to only use pillowballs that have enough articulation and use a good quality bearing.
