I know this has gone over many times, but to actually test to see if I have enough slip on my extended drive line, I need to find something good to flex my rig on. Easy enough, but most likely I will be doing it by myself and since I can’t see under my rig to see if I run out of slip and would therefore ram my DL into my Tcase, I will not know to stop compressing the shaft.

I could therefore destroy my TCase testing to see if my DL is long enough without access to a spotter. SO I need your help. I read and reread threads about lengthening DLs and it was a varied response. I went with an inch and a quarter on an SOA rig. It is a stock driveline that I extended so it still has the original Yoke length.

Will this be enough or should I pull it and give it two inches?

I can’t afford to test it and have it destroy my T-case.

How much compression does a DL actually need? I know it needs a lot more extension, but the up travel is less.
