A year thread but i was wondering if you went with the JKS, and if so if you have been happy with them. I'm thinking of going with them myself.

 

Another dig from down under
Just wondering how the jks arms are travelling myself???
I've emaied jks and they are still in the R&D phase of their rear upper and front control arms, due to the nature of the bends required, its taking them awhile to get the best product possible for us wheelers.

 

question, should you get just the LCA's adjustable or both UCA and LCA adjustables? thinking this would be my next purchase, but still not sure which brand.

 

You can get by with front lowers to adjust your caster angle and rear upper arms to adjust the rear pinion angle. When you lift a vehicle the natural arc will cause the front axle to move backward and the rear axle to move forward. So if you replace both uppers and lowers you can extend them out centering the axles better in the wheelwell and eliminate issues with the rear pinch seam that normally require trimming. This will also give you more suspension flex with the heim style joint that aftermarket control arms have. I have been running just front lowers and rear uppers for a couple years without issue, but I would like to get the others so I can move my back axle back a bit.
