Replace Stock Control Arm Bushings?

Running stock control arms on my 05 TJ, 4.0 Auto, 3" Zone Lift, 33x12.5 Mastercraft MXT on Black Rock Lobos.
Some day I may upgrade all the control arms, but for now the stock ones seem to be doing just fine for the amount of times we are able to get off the pavement. My question: Is there any benefit to replacing the original bushings? I don't notice that I have a problem, just wondering if by swapping them out for new Urethane ones will give me any noticeable difference?

On the lower arms its easier to just replace the whole arm instead of trying to replace the bushings, and they are cheap enough that's the best way to go. The front upper bushings are pressed into the axle and I wouldn't even think about tackling that job again unless I HAD to.
If you aren't having any problems I would just leave the stock arms in and not worry about it. And about the urethane bushings; the stock rubber bushings will give you a much smoother ride, I think the urethane are used for mostly offroad use.

There would be no benefit from replacing your good factory bushings with polyurethane bushings. And it would be a real PITA to do. As stated above, if your bushings are all cracked and worn out, then just replace the arms. You can probably find some take-off's for next to nothing and new they aren't very expensive anyway.

Urethane bushings are good for race cars, not so much our offroad vehicles. The upper bushings that are pressed into the front axle aren't that difficult to replace. The hardest part is getting them out. Plenty of threads on how to do that.
