iam putting in a 4 in rough country lift in my 93 Cherokee and need to know if i have to change anything like brake lines, drive shafts, tie rods. any help is appreciated

 

Brake lines would be a smart idea , Adjustable track bar is also a good idea. As for the driveshaft. You may need to get a sye so keep that in mind that varies from jeep to jeep

 

^^^^^^^^what this guy said.

Plus ill add, it also depends what the lift kit actually comes with. Shocks. Upper and lower control arms etc etc

 

Once you go over 3" of lift the cost goes up quite a bit over most all of stock kits that are sold with items "Not Included" with them. Several of those items have been listed above but not all for sure to do it "Correctly".

The better kits do include most all of the parts for the job except for an SYE when needed but you do pay for them in the total cost.
