so im looking into a BDS 4.5" short arm lift kit. comes with a trackbar, swaybar discos, upper and lower control arms, shocks and springs (full packs), brake lines and a stabilizer.

now, with 4.5" of lift. do i really NEED an SYE? some say i do and others say i dont. right now i dont plan on any serious wheeling right now. i just really need to get all the suspension and bushings done so its driveable without deathwobble.
so i figured i'll just lift it, put the good set of 31's i have on it and just use it as a DD until i get the other stuff like the SYE if i really NEED it to go wheelin.

it depends on how bad the vibes are, i would at least do a T-case drop to help keep it to a minimum. but u cant really know how bad its guna be until u drive it after the lift

I don't know about you, but I'd rather save up a little more cash and do it right the first time. It all depends on your plans with it and how you drive it though.

Jeepjunky

thats what im guna do, but for many people t-case drops work fine

just saying, I didnt have a choice in running a sye or not, with the rear driveshaft that was on my jeep, at 4.5'' of lift it was maxed out, to the point that any travel would have bent / broke it. So I got a sye.

TC drop is garbage, might as well have a 3'' lift at that point. Also, 4.5'' on short arms sucks. Down travel is limited to almost none.

my 95 cherokee is running a 5.5" lift and the slip yoke is basically at it's breaking point so i dont even drive it right now. im waiting on getting a new transfer case and sye. it doesn't sound good or look good

When I bought my jeep it had a 6.5" kit already. with the tc drop it was fine. should you? yes, can you do without for now. sure.

ok, well hows the IRO Hack-N-Tap SYE? is the install fairly easy? good buy for the money? for $200 its the sye and a refurb shaft. or should i just stick with a TC drop?

also looking at the IRO kits, they are cheaper than BDS, plus i could afford their long arm setup. either way i wanna do a kit with all new arms, trackbar, and full packs. $2000 is my budget,

i would stick with t-case drop for now, rough country also sells lift kits fairly well priced if u want to save money

I'm about 5" in the rear with no tc drop and have beenn this way for 3 years or more.it is my dd and vibes were minimal, lately I have noticed more vibes. I wanted to wait for the sye kit to get all the parts I needed so that it would be a 1 time deal when I split the tc. i'm putting in a 6 pinion planetry along with the heavy duty chain upgrade.
I was considering the iro hack and tap but then after thinking and doing a ton more research about it I will pick up a porc sye kit($160ish) and use a front drive shaft for the rear out of a 4.0 aw4 np231 jeep. Jy will have these and for relitively cheap.

did you try to shim the axle?

maybe on stock arms... but a good set of after market arms has a bend or the axle side bushing is offset for more/better clearance...

older xjs seem to have less issues with the vibes i ran 6.5 lift with just the tc drop no issues,im running 11 inch lift now with the tc drop and sye .What year vibration issue stats seem to be 95 and up

ericfx1984

that is because in 1996 the transfer cases got a longer unsupported slip yoke...
