Front drive Shaft Length with Tummy Tuck

I want to hear your experience with front drive shaft length after doing a tummy tuck. I will add mine as I gather the final numbers.

Include:
Suspension lift height-
Axles (stock/modified)-
Adjustable control arms/stretch/change in pinion angle-
Tummy Tuck type/clearance gained -
Front DS length/how much spline engagement at full droop -
Did you need a new shaft? -


You can add any other pertinent information as needed. I have read several threads where a new shaft was bought or the stock one lengthened. Guys had between 1.25 and 1.5 inches left at ride height. I also don't have a definitely number for how much is too little.

Suspension lift height- 3" front, 2" rear
Axles (stock/modified)- Stock D44
Adjustable control arms/stretch/change in pinion angle- Savvy aluminum arms adjusted properly
Tummy Tuck type/clearance gained - UCF UHC with LoPro ~3.5"
Front DS length/how much spline engagement at full droop - Stock, would have to measure
Did you need a new shaft? - Stock shaft with no issues. I have replaced all u-joints

You should be fine with the stock front drive shaft....I've never had to sway from it. Don't have measurements on hand, though.

UCF original high clearance skid.
3" springs.
V8 ZJ tie rod.
Still on stock front upper control arms.
Rusty's adj. lower front arms set as short as they would go. Pretty close to stock length.
Not sure about pinion angle. My buddy is a tech at a dealership, and we put it on the alignment rack to see the #'s. I can't remember what they were, but he said everything was close to being spot-on. I have had no wobble or steering issues whatsoever.


I've been using my un-modified stock front drive line for 3 years after the TT with no issues.

Thanks for the info guys. Keep it coming.

Imped I am thinking I won't I think guys with obnoxious suspension lifts and extra stupid high tcases are the ones with the issues. Mines about a half in ch from the tub at the front cv but I could have changed the setup and got it a bit higher, especially if I didn't have the MML holding the front up higher.

I just figure it would be a good idea to compile a list so we get a better idea as a community how often and under what general circumstances this becomes a problem, because although there is some information out there is seems to be sporadic and unreliable. At least now if someone searches they might be able to get a more definite answer.

Just measured 3 inches of spline engagement at ride height. All worries are now gone.
