JBA Offroad Upper Control Arms And Suspension MEGA Thread BS thread

I'm not sure either, but shipping to me is only like 18 bucks.

 

Ok just to give ya all an update from JBA. Marlin has answered my email on the cracked boots. They sent out new boots right away and have gotten rid of the manufacture of the bad boots. So it seems it was a problem on the boot manufactures end and that problem has been solved by another manufacture.

 

Did Marlin comment on if they will replace the boots coming off of their line going forward? Was just about to order...

 

All the new one should be ship with the new design boots. Boots and joists come with one year warranty

 

Is anyone running 255 tires with jba's and can share your wheel backspacing and if you rub uca or not? I don't really trust the table on their website when it says a 255 and a 315 tire need the same backspacing

 

I want to get the jba, but im still on the fence with the red. Wish it was just black.

 

Have had mine on for a month or so now. By my measurements, I gained about 1 1/8" down travel. Hard to tell for sure if that was due solely to the UCA's as I changed the shocks at the same time. So far so good, but what a PITA to install them. There is absolutely zero slop between the bushings and where they mount on the frame. I wound up chopping up a section of the old UCA bolt to keep one side in place while using a clamp to get the other side in.

 

I believe they are using the good boots now.

 

I noticed the new style boots are held on with a zip tie on the top . Any feed back on how long that will hold up ?

 

I’m also highly considering the JBAs for my 2.5” lift with bilstein 5100 and 888 springs and will soon be with 255/80/17 nitto ridge grapplers. I too would like to know if I’ll have any clearance issues and really want my alignment to be optimal for daily driving and some off road from time to time.. here is a picture of my alignment about a month ago and literally all they fixed was toe pretty much from what I can see

 

Have had the JBAs for almost a year and there is now an ungodly squeak that I've pretty confidently isolated to the UCAs on both sides. Replaced the bushings with correct grease and didn't help anything. Not sure what to do next, but it's driving me crazy.

 

You can always repaint them black

 

You think that will help the squeak?

 

What size tires are you running on your stock wheels?

 

265/75R16

 

Painting the UCAs black was about White Taco 20. Who does not like the red color of JBA UCAs? As for the squeaking, I have not run into that issue yet.

 

Anybody running these UCAs with a 3” lift and 255/80/17 tires? I’m worried about the website not listing them as being able to function with these UCAs. I’ve also got 1.25” spider trax spacers as well

 

I ordered a pair of JBA UCAs I’m running bilstein 6112/5125 w 600# spring. I’m soon going to get rxt icon leaf pack for rear but for now I’ve got the icon 3 leaf progressive AAL. Besides much better alignment capabilities I’m assuming the UCAs will allow for more capability off roading.. would you say I’m losing some Toyota durability by removing the oem UCAs or should these JBAs be just as reliable as long as I keep them maintained?

 

Keep up with the maintenance and they'll be stronger than OEM
