Aftermarket UCAs: Poly bushings vs Rubber can they be easily switched?

Been researching new and used for a mostly street driven truck. So far, going with tubular with ball joint and would like rubber bushings over poly. Can UCA's by Dirt King be fitted with a replacement rubber bushing from say a Dobinson's UCA? to reduce the poly harshness on the road? Are the diameters of frame mount "hoops" on each UCA generally all the same size?

 

It can be done……you will need a press

 

Why not just purchase a UCA that already comes with a rubber bushing in the first place?

 

probably will , but I was looking at a used set

 

Don’t buy someone else’s problem…..get a new set.
Look at reviews, some of these UCA’s eat ball joints like a fat chick in a donut shop

 

All UCAs do not have the same OD for the bushings. I was looking at putting JBA's bushings in my old tubular SPCs and the JBA bushings are oem size(I forget the size at the moment) and the SPC's use around a 2" OD bushing.
