A buddy of mine and me have done some research on arms, and I think we are gonna build some for my jeep. I have 4.5 coils, looking for leaf packs, and gonna drop tcase and go 33s with trimming. However, now im thinking bout going 6 or 6.5 since we are building arms. What more would i need to go the extra 2.5 inches? will a tcase drop and a sye eliminator fix my driveshaft problems? Just curious on difference....thanks!

 

you dont need to use them together , but a sye will be needed for 6 and up for sure

 

yes, but if i do the sye and the drop kit, will i still need another driveshaft?

 

the whole point of an sye is so that the angle of the ds is not a problem because of the new drive shaft that you use. its just a front drive shaft
fitted to the rear now. so you will need a new ds "a front one" with a sye
