Do I need to lengthen my rear driveshaft

[73K5Kid]

Swapped out my 8 inch lift last weekend to a 4 inch. I think I need to lenghthen my rear driveshaft. Here is a pic. The 4 inch lift has made a big inprovement over driveability on the highway. Now when I push my breaks I am not all over the road.

Yes, that shaft needs to be lengthened to were the seal was originally riding (end of shiny spot) looks like maybe 1.5"-2" ?

Thanks that is what I thought. I was hoping to find another way to get around it. I will measure and get to the drive line shop this week. Thanks
