I am putting the Tereflex 4in lift kit on my 07 4dr. Do I need to get new drivlines, or are the stock ones ok for that lift?

 

You will eventually need to get shafts. especially if you flex it. Be careful cause the front will bottom out on the transfer case skid and the exhaust pipe.

 

Keep an eye on the front driveshaft boot, especially if you're disconnecting and articulating the front axle alot.

 

Rear ds will last a long time unless you bash it. Front, as others have stated.

 

Just ripped my front booth on that Big Bear run a week ago , I'm sure you'll get there too

 

yeah your front drive shaft is toast . my TF kit has been on for a few days and the front drive shaft is spewing grease lol .

 

I have a Question can you run woods or tereaflex drive shaft in the front and a stock shaft in the rear .

 

I run a Tera ds in front and a stocker in the rear.

 

thanks for the info how long have you run your JK with the TF front ds and the stock rear ds

 

I just got the Tera one about 2months ago, before that I had a JEReel(it had the OE flange,caused too much noise at the t-case) . I've been running an aftermarket shaft in front for around 30,000m now.
8000m-18000m - 2in BB(stock shafts)
18000m-38000m-4in superlift( added frt je reel somewhere in that time)
38000m-60000m-4in TeraFlex(added tf frt ds about 5000m ago)
These are rough estimates from memory, still running the stock rear shaft after 60,000m, but I only wheel on average once a month, sometimes once every other month. Plus we don't have rocks to drop on around here. If I wheeled in rocks and/or was able to wheel more I'd change it just because of the ability it gives you to change u-joints if they break. For now, I'm gonna just run the stocker till it goes or I get the extra funds for another TF.
