No, because u have a 1 inch raise in the box it self..neutral is the top hole !!!! Which would only give u straight setback and would not do any good , since for every 10" back u need to move min. 1" up ( ruhle of thumb ) !!!

The middle hole is roughly an inch up,
the top hole would be the neutral setting.

Mine are in the middle hole, and you can see that
they ( the driveshafts) angle upward somewhat.

Stellings ad even says " when installed in the middle hole,
it gives you an inch of raise"

Mine is nearly the same with 12" driveshafts, except no couplers.

Yes Im trying to ditch the drive shafts and go with the long IMCO shaft. I'm trying to figure out if I need to move the extension box to do it though? Still trying to determine what neutral height is on the box?

The drive shafts with U Joints will give you a little room for error in alignment. Call Stellings to find out where they say neutral is.

Thanks Griff, I will give them a call!

Neutral on the Stellings box is 7/8" up. Neutral is the top set of holes. You should be able to get the 7/8" up with your stock mounts so long as you have hatch clearance. Keith I have the set of the stellings shafts that came with the boxes if you need them. Personally I didn't like the extra long straight shaft. Figure theres alot of twisting going on there?

Stellings box= no coupler= boxes and boxes$$$$$of broken XR drives...get out your wallet

Thats why I went with the drive line set up and shafts and thats why I think he wants to use the Imco long shafts so he can use the couplers?

Do you have any pictures of your setup?
