RK's normal x-factor control arms move the rear axle back over 1" In some cases this can cause a few issues if the installer or xxx shop did not set them up correctly. The swaybar needs to be moved back 1"to clear the bump stops and UCA mounts. A wider bodied shock can come in contact with the track bar bracket. Bowed coils. 2 doors will have more issues because of pinion correction.
I did not want to move the axle back 1", just enough to center the axles in the wheel wells. Lifted 3.5" only requires maybe .5 over stock on the lowers.
RK has 2 part numbers for rear lower CA's. One short (run with stock uppers) and 1 set of uppers (longer and run with the longer lowers) This year RK is releasing a shorter set of rear uppers to be run with the shorter lowers.
RK will also custom cut any arm length you want. I wanted at least .5 on my rear lowers, and enough to set pinion with the uppers. You'll see even .5 the coils have s slight slant and the links contact.
I thought I'd try to clear the confusion when choosing RK arms. Of coarse RK's been great and always willing to help if you call.
