I have a 1988 jeep cherokee with np242 transfer case and i want to lift it 6.5" should i do the SYE or the lift first?

I am probably going to go with the Rough Country 6.5" X-series Long Arm Suspension and it says i should get an SYE along with it, but they don't sell and SYE for np242. I'm also aware that i have to do a Hack n tap for the np242.

I saw that tom woods does the Hack n Tap for you, and you just have to send them your shaft from the transfer case. Has anyone tried this? is it easy to install?

If you do it before the lift the new rear shaft will be the wrong length after the lift.

so then i should lift it then do the SYE?

Does anyone know how hard it would be to install the RC 6.5" lift?

and will it be possible to drive it with the lift without an SYE( for a few days only )

depends......do you know your way around a vehicle and what kind of tools and equipment do you have at your disposal.

installing a lift is by no means a difficult job, however if you are not overly mechanical than it could be a disaster.

its not going to hurt to drive it for a few days with the lift but at 6.5" your going to be stretching that rear shaft and that slip yoke pretty close to its limits but should be fine for street driving, better off to pick up a front drive shaft and do the SYE when you do the lift and run the front shaft in the rear

I'm thinking about OP question as well....

I have enough $ for any SYE (but a $ shy for a lift kit) and was wondering if i can install SYE with stock DS without any lift .

Yeah i believe i would have all the basic tools needed but are there any special tools i should have? like a transmission jack or some type of puller?

Nope you just need a bunch of wrenches in metric size and a regular jack pretty much.

buy the SYE and install it, measure once its at height and order the shaft. You can't cut corners at 6.5"; not much works up there

If you are going to do the sye kit yourself, get a GOOD pair of snap ring pliers...the ones with the flat ends...NOT the small points.

And you need a fair amount of patience and persistance if one or two snap rings give you trouble. They can be pains in the ****, or you could just get lucky first try.

Or go 4.5 long arm like i have and you wont need a SYE

4.5 still need an SYE.

You MUST install the SYE first/at the same time as the lift if you plan on driving it, and use a stock front driveshaft as a rear ds temporarily till you get one the correct length. A stock rear DS with the slip yoke will not be long enough for a 6.5" lift, and will bind like a **** (if it doesn't fall out first).

Try to get the longest front shaft possible. You'll find the longer ones in ZJ Grand Cherokees. Here's a great list to help you out:

what does a long arm kit have to do with the driveline angle in the rear anyways?

dukie564

nothing....

I drive mine at 5 inches long arms and no SYE and barely any vibrations
