JBA Offroad Upper Control Arms And Suspension MEGA Thread BS thread

Funny
Your pic is "chop shop" and folks listen to your statements?

What is "gimmicky" about having more adjustability.
Near as i can see is "ignorant" to how they actually function.

And whats with all that toe in in that last pic posted? Thats the recomended from JBA?
That will eat tires with all the toe in.
The caster is just allmost into the sweet spot 3.5 to 4.5, might not wander all over the place just going straight.

I am just shadetree so take with grain of salt.

 

The gimmick is that any other position in SPC will result in crap wheel placement inside the wheel well.

 

From what?
The recommended "D" setting.
Some have found that by adjusting the balljoint setting, which is not on any other UCA, is offering more clearances with a "G" setting at the SPC UCA, for 35" tires...so as not to rub the body mount.

Not only that the SPC gives you an adjustable camber, no others have that.

Most of that bad rep these SPC got in the beginning seemed to me like bad installs from folks that should not have been working on these in the first place. Utube mechanics.

 

@BackOff I think you hit the nail on the head. I bought my first set of SPC arms before there was even a JBA option. With 34's I found that "E" helped with the cab mount rubbing and now with 35's the "F" position is ideal. I have a plate bumper which allows for the tire to be pushed forward without rubbing. It would be a different story if I still had the factory front bumper. Still getting 4 degrees caster in the "F" position since the lower cams are maxed in at the front & out at the rear. With that said, if I had to buy another set of arms and I was keeping the factory bumper, I would definitely give the JBA arms a try. I like that they can take a off the shelf ball joint and I know he stands behind his work....

 

Then go get you some SPC's. I know there is a fan club for em, but I deal with diagnosing issues with them more than any other brand. When I install them, they are done correctly.

 

Have had SPC since 2011...zero issues.

 

Also have had SPC, all issues, but I also wheel the fucking shit out of my truck. SPC is good for a pavement princess.

 

Sure thing bud.
And by the way "castor" is oil.
CASTER is something you can adjust.

 

Ah, you're also a grammar enthusiast, you mom must be so proud.

 

All brand loyalty aside, I've "followed" @Texoma 's work for a few years now. He has a good reputation and I would take what he says to be truth. He's installed a TON of UCAs on multiple variants of Toyota "trucks".

Let's keep this thread on track for just JBA stuff.

 

i run the JBA HD high caster arms along with the TC cam tab gussets. 4.5* caster for the last 40k and i wheel the crap out of the truck.

 

If it helps, the max caster for a 3rd Gen is 2.9 to remain within "manf" spec and in the green from what I'm told/read. In Hawaii, we need to show proof of the alignment spec sheet to pass an inspection. When I added the JBA's a few weeks ago, I specifically told the Tech I wanted 2.9 and 0 on the others. He got it as close to possible, all green and it rides so good with the Eibach kit. I hear the higher 3-4 Degree caster is even better with bigger tires but we're limited here to stay in spec. Prior to the JBA, I was at 0.9 and 0.2 caster.

 

I did at first wonder why chopshop thought spc was junk.

I see now that i am just some clueless mall crawler and a grammar enthusist...lol.
I miss used castor and caster myself before, though maybe chopshop would maybe like to not sound like a idiot.

OK
Back the the JBA fanboi thread...bye bye.

 

Bye

 

LOL

 

What does everyone do with the abs mount/wire? The hole is drilled in the arm but mine won't reach. Ziptie?

 

It should. You can unhook the wire from the clip, bolt the clip on, the get the wire back into a spot where it looks good at full droop. Its a bit tighter, but it should work.

 

Mine reached. But I had zipties ready for back up. Just have enough play in the wire for movement.

 

These work well, can use the original bolt

 

This is what I've been putting on all my customers arms instead of the stock abs holder.
