drive shaft ?

[bmaley79]

How much lift would i have to have in order to use my 2wd drive shaft in my 4wd truck?

[Geonovast]

Probably about 48 inches.

 

You need a shorter shaft.

Lmao ok I was just trying to eleminate having to extend both drive shafts. The 2wd drive shaft is only 6 inches longer than the 4wd one. BUt i wasnt shure what that translated into lift wise. I'm planning on doing a soa and add a leaf and extended shackels. and then what ever to the front to level it out.

I had to lift 3.5" to make a 1" longer rear shaft work......so about 28" of lift and you will be golden :clapping: :yes:

You can use pythagorean theorem to figure it out

drive shaft lenght^2-lenght from transmission to diff after tc added^2 = amount of lift need^2 to keep drive shaft. Would be an interesting problem to run the numbers, but yeah, you would need a ladder to get in the cab I'm guessing ;)

You want to go spring over for 5-6 inches, add a leaf for 2-3 inches, and extended shackles for 1-2 inches???? that between 8-11 inches of rear lift!!! Youll need long arms up front to make the front work properly.... and thats if you can find springs and shocks long enough to "level it out". Very ambitious.... and very expensive. If you can't afford to have a shaft shortened, you can't afford to lift the front that much. I'm not sure what your final plans are, but to keep things reasonable, I would stick with a spring over only in the rear, and a 4.5 inch kit in the front with a spring spacer, and control arm drop brackets with custom control arms. Still expensive, but within reason. Let us know what your plans are, I'm very curious!

I had to hack 11 inches off my 2wd one for 4wd. :hmm:

2wd shaft is 10 to 11 inches longer than a 4wd one, not 6.

Can you say "Comanche Monster Truck" Move over Gravedigger here come the Manche!

Its just going to be a toy. Long arms is no big deal I fab them up and as far as coils in the front i was thinking coil overs may just do coil overs on the whole thing havent decided yet. I hate balancing drive shafts is the only reason I wanted to keep the 2wd one but ill just cut them both. no big deal. It just has to barley pass inspection that way i can drive it down the road to get on the trails.

8" isn't too bad, my old Cherokee was running that easily (I was running long arms though). There's a guy in town that runs about 11" on his Comanche with 40" Boggers and was running short arms. The Jeep ran rought but went straight down the road. He has since went to leafs all around with 3/4 ton axles.
