thx dom abouts what will the sye and rear d/s set a fella back?
Pls correct me if i'm wrong.....the SYE is about 250-300 depending of which kind you buy. Since the XJs have along driveshafts so you don't need a super short SYE. Your DS angles should still be ok with a longer SYE. It's another story for the TJs.
if you go with a SYE you won't have to drop your T-case. You will have a bit more clearance. I have a 6" lift now with an advance adaptor SYE and I have not drop my t-case. I have no vibration in the DS what so ever.
