These joints would be for the front track bar for the suspension that I am building for my TJ. First off, would I be better off with a johnny joint at each end, or a johnny joint and bushing at the other end? I will have 12" travel shocks so the joints need to have a decent amount of range. My concern with johnny joints at each end is that more vibrations might transfer to the frame and there is also a greater chance for the joints to loosen up and cause sloppy steering and death wobble.

If I use the johnny joints, I want to use the narrow 2" forged joint w/ 1" shank.

But I haven't found a poly bushing that is the same size to use on the other end of the bar.

For the lower control arms I am using a 2.5" JJ w/ 1.25" shank on the frame side and a poly bushing from poly performance (PPM-4304) on the other side.

For the single upper arm I think that I have decided on using 2.5" JJ's w/ 1" shank on both ends.

Does that sound like a good setup for the front suspension or should I change some joint sizes, or look at different bushings? I'd appreciate links to some other quality bushings so that I can check them out and compare. My main interests in the bushings are to find ones that have a 2 5/8" mounting width and 9/16" bolt for the control arms to match the 2.5" JJ's and a 1.6" mounting width and 14mm bolt for the track bar bushing to match the narrow 2" Johnny joints.

Or, if the JJ's are durable enough to use for both sides of the track bar without developing play sooner than a bushing, then I will just get 2 narrow JJ's.
