I am very far from an expert, but from what I know that should be fine. I am not familliar with the sye requirements though.
I know that it goes against all reading material, but I lifted my 87 yj 7"of suspension and 3" body. I am still running stock driveshaft. I was worried about it at first but it has given me no problems. I don't climb or severely off road mine though either.
