I have a 97 jeep Cherokee sport my tcas leaks bad so it's time to rebuild it I have a 6.5 long arm kit so I think the sye is neccesary. Can anyone lead me to some rebuild kits that are gonna last thanks so much

 

There are two kits here:

There are several different ones out there and "most" are priced according to the quality of the SYE but not all. I will refer to members with experience with different brands my advice wait for them to answer at 6 1/2" of lift you have a lot of angle to deal with plus you will need shims as well. I had to shim mine even at 4 1/2" for the proper angle's.

 

I haven't had an issue with the angles so far it's been 2 years since I lifted it and I drove it 66 miles daily to and from school
