Driveshaft question regarding 7" lift

[drw18]

Hey everyone,
This week I am putting on my 7" lift which consists of:

Front:
3" spindles
4" Torsion Twist

Rear:
5.5" SOA
1.5" Add-a-leafs

The big question is.... Will I need a longer driveshaft and where do I get an extension? I drive a 97 XLT.

5" torsion twist? Does your truck just tip over when it hits a pot hole?

4in TT... that sounds real good... Smooth like a caddy... Sounds to me like if you could even get 4in out of a TT that it'll be maxed and drive/ride like crap.

With a spring over and the rear axle reindexed you may or may not need a new driveshaft. I know one person who did not need a new drive shaft after going soa and i know another one who did.

I would be more worried about replacing my cv's once a year after that much tt.
