if you call wooders and actually talk to him he will be more then helpfull, they seem to be really busy and sometimes dont reply back to the hundred of emails they get
you need the sye to fit the double cardon driveshaft and by these two parts together you able to have a longer rear driveshaft as the stock ones are too small, but then you need to rotate your rear pinion angle to get your driveline angle spot on! if you dont do this you will break rear univesal joints because your driveline angle is at too much of an angle due to the pinion angle
thats why when you correct pinion angle you need a sye,dc driveshaft and rear upper adj control arms all together to do this!
and you need the trackbars because once you lift your jeep the axle shifts no longr being center with that car which can cause un even wear on your expensive tyres,
the key to a good suspension lift is to have everything square/centered with each other and if you can lift your jeep 3.5"s while trying to keep the right control arm length, driveline angle,axles centered with the trackbars/panhards everything will be center and it will drive smooooooth
let me find a video of this jeep thats got a 6" lift but it has adjustable arms and trackbars and he actually adjusts the so you can see what everything does!
here you go, there are 3 parts to the video, this is only part 1 but watch how he adjusts everything and you can see how the trackbars allow him to align the axles back to center, and how his control arms allow him to fix his angle, yes its a totally different kit as he has a triangular rear arms but you can kinda figure out hiw it would work if you didnt have the trangle system and if you have a trackbar
