Lift questions?!?!??

Hey guys I just started installing my 4.5" Rough Country X-series lift. I got the rear done and put some new shackles that are 2" drop from auto-zone. I am done with the rear. My question is when all said and done will I get away with no SYE needed off the bat. I understand most need it in future but how long can I last without. Also kit comes with a t case drop which should help as well! Please give input in your rides and suggestions! Thanks

Start with what you have(tcasedrop) and you might just be alright at that height. 97+ are more common for vibes but ive seen a 98 at 9.5 and 8.5 actually drive just fine with only the drop, wears out your joints faster

Yea that is good idea! Mine is a 96 so hopefully ill be fine. I finished rear and drove down road today and it vibrated like hell! But hopefully that's just because once side is so much higher

You will need to drop your crossmember using a spacer kit or install a SYE to avoid driveline vibrations even when you do get the front suspension in.

4 degree shims for your rear axle perches will help point the pinion up at the Tcase where it belongs and that will help quite a bit too, but the slip yoke being pulled out and at a poor angle for 1 Ujoint can only be corrected with a SYE and double cardan driveshaft.

Baseline outfiters sells a complete SYE kit for 150 on sale once in a while and usually around 170. IRO sells a HnT SYE for about 50 less.

A front driveshaft from any automatic XJ will be a good replacement for your rear DS when the SYE is installed.

A 8.5 and 9.5" lifts with only a t case drop and no vibes? No way. The driveshaft would fall out, especially if it was articulating the suspension.

SYE's are required for lifts past 4.5" I would not drive it until you do a SYE
