JBA UCA's With 255/80/17 on Fox Pro Suspension

Question regarding JBA UCA’s. I have trd pro suspension and will be putting the Eibach pro spring lift kit on it. With 2.6” lift from stock, I am looking to purchase aftermarket UCA’s.

I’ve seen the the tire sizes on their site that will work without spacers but I find it weird that 255/80/17’s aren’t listed. I’ve read a few posts that say that tire size will work, some don’t and some have minor rubbing at FTTL.

I’ve searched and could not find a solid answer. Any help would be appreciated.

 

If JBA's won't fit your application check out Dirt King ball joint UCA's or Dobinson UCA's. Either of those will work.

 

I have JBA arms with TuRD Pro wheels and 255/80/17 Ridge grapplers with no issues and plenty of room.

 

Hey Agent_Outside, which grease do you use on your JBAs, and have they ever squeeked? JBA says lithium, but others say silicon.

 

Greasing UCAs

 

Thanks, that’s a whole range of opinions now, haha. Someone who knows said Redline red moly. I’ve used green grease, as well, for other steel type applications. I guess they’re all good and everything works, so what’s best? Some say the grease that sticks around is the best, which is perhaps why JBA recommends lithium. But the stickiest of them all has to be silicon if that’s the criterion.

 

Redline doesn't last long or on mine it doesn't.

2 months later and maybe only 500 miles it squeaks. Going with Green Grese this round and see how long it lasts.

 

I just put mine on so they don’t squeak yet. Just trying for preventative maintenance. Maybe I’ll try silicon and we can get our own comparison going.

 

Yes!! Can you post some pics?!

 

there’s thousands in my adventure tread. That setup has been installed since the bottom of page 4. https://www.4runners.com/threads/agent_outside-adventures-in-a-4runner-limited.8250/
