JBA off-road

[G_Raw]

I can't speak for JBAs. I have talked to forum members and folks on trails who have had their SPCs slip and misalign after flexing all weekend. I personally went with a uniball set up...I'm not disappointed :banana:

I have JBA UCAs...zero complaints.

google SPC 25460 vs. the JBA arms you can see the design is nearly the same minus the “plate” portion doesn’t extend onto the tubing part with the SPC nor does the SPC have the the little flange tabs. For the price I wish I had looked into JBA a little more but the general consensus seemed to be Total Chaos uniball or SPC adjustable with boot style and I didn’t want a lot of maintenance. Another reason I went with SPC is so I can put it on the “G” setting and move the tire forward.��

I’d be surprised if that SPC forging didn’t have nipples that extended into the pipe sections for strength and alignment.
Not that it matters, if they don’t break, then they’re plenty strong for the job.

I’m a little surprised folks are so polarized over upper controll arms. Both products look good to me, but I don’t own either.

I'm having trouble visualizing why a gusset is needed there at all - there is nothing to limit travel at the pivot, so I'm not sure why that joint would be under stress. Is it possible the failures were because of poor weld penetration?

I'm not sure, I think because bushings are not free moving? As in, they are resistive? Struggling to find words...need coffee...

It looks like all of the "better" quality UCA's have these little flanges. It definitely makes mechanical sense to me, perhaps it's just for maximum integrity?

I’m not a mechanical engineer, but I’d expect the sheer strength of the little bolt (uni-ball pin) holding the knuckle to the UCA to be the weak point of that setup regardless of the use of those gussets.

does it say Made in China on the box or on the UCAs?

I just received my SPC UCA’s and I will say they look VERY similar to the JBA arms. The ball joint is OEM style and has 80 degrees of flex. I ordered them them Toytec lifts and they get them straight from SPC performance in Longmont,CO. Designed, engineered, tested, and assembled in COLORADO.
