Are The Crown Leaf And Shackle Mount Bushings Ok?

My leaves and shackle mount bushings are gone. I see crown sells a set. Some of their stuff is good - some of it is awful. Where do these bushings fall?

 

On the awful side of good. I think they sell omix-ada stuff repackaged as crown automotive.
Buy a set of warrior shackles. Then it's set for the rest of your life, and the jeeps!

 

I don't care for Omix-Ada parts at all. However I am running their HD greasable shackles and bushings. I like them allot.

 

I've used these over the years . if all your going to do is bushings . maybe 20 years with last set
Energy Suspension Front or Rear Spring Bushings for 55-75 Jeep CJ

 

Warrior sells just bushings?

 

To be clear im looking for bushings for frame and leafs not new shackles.

 

I used prothane. If Crown lists them as rubber then I'd avoid. Crown/Omix lost their recipe book for making real rubber years ago.

 

Thanks for the input folks. I really do want rubber not poly for better flex (although it looks like there is almost no rubber in there so who knows if rubber really helps flex) It looks like I can still get rubber through Dayton/Moog/AC Delco but I'll just have to pay a little more. That is totally fine. The crown set really doesn't look like it will make it more than a single trail ride before a couple hard flexes pushes the rubber out.
