JBA Offroad Upper Control Arms And Suspension MEGA Thread BS thread

Hopefully it wont need too much adjustment at the LCA's. The shop that just aligned it bent the frame tabs and air hammered them back instead of letting me know it needed bushings and adjusters.

 

Ordered a set today,plan to drive mine the next ten years so might as well.

 

You'll be glad you did.

 

Watched some videos on the install and any tips in general and for the tru bolts?
Saw a few that were installed backwards .
2nd gen

 

You have to bend the sheet metal pinch weld back an inch or so to get the bolt to go through. Then you just bend it back into place.

 

Yeah it made no sense. They said no point for local pickup since it will be same price regardless if shipping

 

Sometimes just the interaction is great for customer service.I do bussiness a lot based on that alone.

 

After ordering (of course it was after) I read on their site that these UCA will not work with 255/85/16 on stock BS for a 16x7 rim. Can anyone confirm if they do or do not rub?
I added a pic of my tire/wheel combo. I searched some other threads and found nothing concrete. TIA!

 

I plan on 255/80/17 with 17x7.5 steelies with 4.5 inch backspace.
Should fit perfectly via there chart.

^whats your backspacing?

 

It will work as long as you go ahead and put 1 1 /4" spider tracks Spacers on.

 

Does it rub the ball joint protrusion or further up on the arm when turning?

 

Whats the backspacing?

 

From what I found on TW its "TRD Dark Anthracite
Part# PT946-35160
Dimensions: 16x7 +25"

 

From what I can tell and what's on JBA's website, its 5" backspacing?

 

No, not with the spacers and your oem backspacing. Iran, the same type of spacers on my oem rims before I upgraded two different backspacing wheels. Works absolutely fine.

 

Sorry, I meant to ask that question in this way; Without the wheel spacer, but with the JBAs installed, will it rub the ball joint or the or the arm tubing when turning? My apologies.

 

Ok so 3.5" to centre of wheel (half of 7"), plus 25mm (1") offset = 4.5" backspacing. Your good.

 

Thank you for the response and the education! Much appreciated.

 

Without the spacer, the tire is going to hit the uca when it turns inward.

 

Does the standard jba protrude more than the factory uca?

I’m going to put front lift and new jba’s on this weekend but for reference i have an old 255/75/17 and fj 17x7.5 steelie I threw on real quick and snapped a few photos.
I plan to run a 255/80/17 with the steelie.
Here’s a pic stright and turned each way.
