On the 4x4 NNBS Ex Cab Std Bed trucks do you need an extended driveshaft or notch the xmember when putting on 8+ inches of lift in the rear like on the crew cabs?

No, from my understanding this occurs only with 2wd trucks because their driveshaft is longer due to lack of transfer case. My brothers is up 8.5" in the rear and mine is okay with 7" of lift in the rear. Doesnt even come close.
thats what i was thinking, cuz i know at least on the NBS X-cabs 4x4s have the single solid driveshaft and 2wds have the wierd 2 piece one.

Get a 4x4 and call it a day :read:

I'ld never buy a 2WD truck to lift.

JAKD-UP when are you putting on your lift? let us know if you have to do any modifying?
Your guess is as good as mine. Me and the shipping store are currently fighting with UPS on it. I'm either getting the money I need for the missing parts or getting the money to buy a new lift. UPS has tried to deny the claim once but that shit didn't fly. Hopefully soon I will get it all figured out.

I wonder if this is a problem with the RCSB 2wd trucks
i have an issue with mine at EC :shrug: thats why i havent lifted the back of mine more. (yet) I will be here shortly but i have to buy an extended driveshaft as well as new shocks and rear springs

Will, or someone with a NNBS 4x4 if you could, measure the driveshaft length. From the center of the bolt that connects to the tranny to the back by the axle.

i dont believe there will be any difference in length meaning yes, you too will need an extended driveshaft over 8 1/2" of lift

I dont mind extending the d-shaft...I just dont wanna modify the crossmember.

Wonder if some company will ever make a special crossmember for these lifted 2wd's

^^^ That sucks man!!! Where did you order it from again?
I bought it off a member here. It was noone's fault but UPS. I'm missing like 400$ worth of parts and they are making it a bigger deal than what it really is. So if I have to do something to my driveshaft at this point it wouldn't surprise me. When it rains it pours!

Yeah I'm using the spacer. I figured I mine as well try and use it since I bought it. Plus the extra lift is a plus.
...and just the fabtech + springs = Rake :supergay:
