Future-Proofing Driveshafts for 2005 TJ – Advice Needed

[richardh]

Hey all, I’m trying to future-proof some upgrades on my ’05 TJ and could use some thoughts.

Current setup:

• 2005 TJ
• 4” Savvy lift on 35s
• Rear: Super Dana 35 w/ chromoly shafts
• Front: Dana 30 w/ chromoly shafts
• Driveshafts: Adams 1310 double cardan front and rear

Current Project:
I’m swapping out the leaking NP231 for an NP241 and finishing a tummy tuck, raising the transfer case ~3”. This changes driveline geometry:

• Rear: New t-case flange + 1330 yoke, plus about 2” added length
• Front: Yoke is different, and length is up about 2” as well

Next Project (6–12 months out):
Saving up for JK-width axles from Currie:

• Rear: Currie 60 JK Hybrid High Pinion
• Front: Currie 44 JK Hybrid High Pinion
  These usually come with 1350 yokes (or I can spec them that way).

Driveshaft Plan (trying to avoid buying twice):

• Rear: 1350 double cardan shaft with flange + 1350 U-joint. Use a 1350 x 1310 conversion joint to run with my Dana 35 until the axle upgrade.
• Front: 1350 double cardan shaft, swap in 1350 yoke at the t-case. Use a 1350 x 1310 conversion joint to run with the Dana 30.

Questions:

1. When ordering the shafts, what length should I use?
   • Rear flange-to-yoke is currently 17 7/8"
   • Front flange-to-yoke is currently 41"
     Should I order based on these, or adjust for the future axle swap?
2. I assumed the Currie HP axles (with larger center sections) would result in slightly shorter driveshaft lengths, but I’m finding mixed info. Has anyone run into this?
3. I reached out to Adams for input and got the usual “measure when you install” response—which isn’t super helpful when trying to plan ahead.

Appreciate any insight or real-world experience. Thanks!

Best bet on ordering driveshafts is to call Tom Woods and walk them through what you want. They can then help you with what works, and why. @Shawn at Tom Wood's can help!
