Sorry to jump in But the 1" TC drop is only to correct your drive shaft angle and to keep most of the sliped end in the TC.
Otherwise a longer drive shaft is needed at full articulation so your shaft wont fall out.
The SYE is for when you loose your drive shaft that you won't loose your fluid and burn up your TC.
Then comes the CV joint drive shaft. Now this baby will keep vibration down to a min.and you can have a high lift without the 1" TC drop. That means more ground clearance.
You don't think 1" makes much difference just wait until your rock crawling.
