Measuring driveshaft with an sye

Well decided to order an SYE from Advance along with there drive line. I currently have a 3" lift and a 1" TC drop. Do I leave the 1" drop in place & measure the drive line or should I get rid of the drop put it back where it belongs then measure the drive line? Because I think it will make a difference on the measurement of the drive line won't it? I really don't understand how the CV joint drive line works, with the rear end going up & down doesn't the measurement change?, I guess its always the same length like a arc. Please help I don't want to screw this thing up, I've read where some guys need both the 1" drop & the SYE thanks!

The tc drop won't really add much to the length of the driveshaft. It will add to or change the pinion angle though.

Nobody has ever needed a 1" drop and a SYE. The motor mounts can be lifted to give a little less drastic of an angle to work with though. Drop off the xj shaft at your local driveline shop. Install the SYE without the transfer case drop. Call in your accurate measurement. Pick it up once you've buttoned everything up.

The tc drop defeats the whole purpose of a SYE, get rid of it. The CV has a slip built into it as the suspension moves it slips with it. To measure for a cv you want the weight of the vehicle on it. Then measure from tc yoke ( the flat mounting part not the cup) to axle yoke. If you are having it made by a pro he will know what to do with that measurement.

I had a tcase drop on my TJ n I had some vibration on the highway. I went to a SYE and cv driveshaft got rid of the tcase drop n never had any problems. Oh and if your looking for a good place to get a custom cv driveshaft check these guys out

They were very helpful n the driveshaft was great.
Sold the jeep to a friend n he said he hasn't changed a thing
If it can stand up to his driving it will hold up to ANYTHING!! Lol

Order the Sye first. Install Sye and remove tc drop. Then measure and buy the dc shaft.
