JBA Offroad Upper Control Arms And Suspension MEGA Thread BS thread

In my area coaching was required. The JBA instructions have alignment numbers in them so I provided that to the shop and they made it match as close as the truck would allow.

 

Oh thats super nice. I'll definitely make sure not to throw away any instructions out of habit

 

This. Now the guy who did mine is experienced in aligning lifted vehicles so he got mine dialed in perfectly. He works for a large chain tire shop but he has a contract through a 4x4 shop do alignments for them there.

 

I’m looking to get some 285/70/17 tires on some 17x8.5 -10 offset stealth custom gen 5s. At the same time I will be upgrading my control arms and was thinking about jba but I’m seeing that some people are experiencing rubbing issues. Is there anyone out there with the same setup? Was there any issues?

 

This should be fine I have the exact same numbers with no rubbing.

 

I read through the first page of this thread. Questions I have if anyone knows and cares to share, thanks.

There were some issues in the past but that was all fixed somewhere around 2015? and since then no major issues or failures when it comes to ball joint or bushings?

How many miles can you expect to get out of these ucas before anything on them needs to be replaced?

People running them with 35s? Not skinny 35s

 

Any pictures of your setup brotha?

 

I have 1.25" wheel spacers, JBA UCA's and my FNFX wheels are 0 offset, tires are 285/70/17. In the process of getting some Ray 10's -10 offset, should not have any rubbing issues! Getting rid of the spacers with the new setup.

 

Is anyone here running JBA with a level kit and 265/70R17? 1.5 inch front or about that. I want to get my Camber at 0 without sacrificing Caster. Right now the best I can get with stock UCAs is +0.2 Camber with Caster between 1.2 and 1.3. The truck doesn't feels stable on the highway.

 

Hi all,

Can you replace the zerks on these? My control arms have about 100k, imagine that! And they won’t take grease anymore, which might become a problem. Thanks!

 

Yes, contact JBA and they may be able to get you replacements, but i would look at replacing the bushings also.

 

Yes, and I just replaced my bushings and ball joints, go to the web site, cheaper than buying new UCA's

 

Id be shocked if they werent just normal 1/4-28 90 degree zerks

 

Can anyone attest to this?
