JBA Offroad Upper Control Arms And Suspension MEGA Thread BS thread

Much better. And I can reverse at full lock without rubbing which was the one problem spot before, so there has been an improvement over the initial state as well

 

Good. That's how these things are supposed to work.

Also @Blackout14 when is the LT kit coming...

 

Subd for JBA long travel kit...

 

I dunno if I'm overthinkin' this but I'm a little confused. Should I order the standard arm or the high clearance ones? I'm only goin' for like a 2" lift with the TRD Pro kit but I'd like to switch to 17" from 16" wheels. Nothin' crazy for tires either.

 

Go for the high caster ones. The standard ones are for stock height trucks.

 

They both share the same kind of ball joint don't they.

 

I believe so, yeah. I think all of his Tacoma arms do. The difference is in the arm itself and how it’s built.

 

Eh, but I got standard travel now with cam-tab gussets. How about a 2+ kit with greasable ball joint and... maybe heims? Delrin bushings work too though.

 

Adding Caster to the UCA pulls the top tire towards the rear, and when taken for an alignment the LCA adjusters push the bottom of the tire towards the front.


I currently have SPC ucas set at two different caster settings.. More positive caster I am rubbing the firewall, less positive caster I am rubbing my bumper. I need to cut my bumper and then set them both to the lower caster setting. Lower positive Caster settings does not mean less caster overall, it means that the LCA adjusters have to be used more to get high positve caster.

 

Finding a good alignment tech that is willing to do their job is the hardest part..

 

Seems low. Back to rubbing at lock in reverse.... But the professionals know best, right!?

 

It is low, needs to be at least a degree higher on caster

 

Would these be a good fit for my truck? I have a 6 inch lift with 35's and my UCA's look a bit rough..I was looking at these and the light racing ones..

 

Does JBA have less clearance to the tires than the stock UCA? For example on 255/85/16 tires on the stock wheels, it doesn't rub stock but will rub for JBA?

 

255/85/16 on stock wheels rubbed on the JBA's for me. Added wheel spacers to fix

 

Depends on your wheel specs. I’ve never had a problem on or offroad And no spacers.

 

Oops. All I saw was stock tire. Thanks

 

Took it back to Firestone. They did better this time.

 

Are these numbers good?

LF camber 0.1
RF camber -0.1

LF caster 3.6
RF caster 3.3

RF toe -0.03
LF toe -0.03

Steering wheel seems slightly off.. and traction control light is on..
