Does anyone know if the 4X4 and 2 wheel drive use the same size rear driveshaft or is the 4X4 longer.

Thanks

 

I believe they are the same, for a given bed length (two piece vs. one piece on long bed on a supercrew?).

 

What about the transfer case (length)?

 

I would assume the 4X4 has a shorter driveshaft all other things being equal

 

Let me give a bit more info on my question, and thanks to your replies so far. I am in the martek for a new F150 and would like to do a three inch lift all the way around for as little $$$$ as possible.

I contacted "Fat Bobs Garage" who has a three inch spring spacer for the front and a two inch add-a-leaf for the rear for the 2 wheel drive. I asked if the add-a-leaf could be used with a one inch spacer block for the rear for a total of three inches all around. The reply I got said that they have never tried it but could only see some slight vibration due to the rear axle angle, if any thing at all.

My question about the 2 wheel drive and the 4X4 is this, Fat Bob's also has the same kit for the 4X4, if the 4X4 comes stock with a one inch spacer block (which it does) then the only differance with the 2 wheel drive as I have asked could be the leagth of the rear drive shaft.

So agian does anyone know if the 2 wheel drive and 4X4 models use the same shaft or is the 4X4 longer? The transfer case should not be the issued as someone asked above, the 4X4 is still a 2 wheel drive with a front shaft, correct?

Any input would be greatly appreciated, thanks to all in advance.

 

The 4x4 shaft is shorter.

 

The 4x4 one is shorter due to the transfer case. The transfer case is attached behind the tranny then the drive shaft to the axle where as the 2wd has no transfer case so your drive shaft should be longer.

This should be ideal as you would want a longer driveshaft to reduce the angle on the pinion yoke. A shorter one will have more extreme angle. As to the actual length, i am not sure what the width of the transfer case but I would venture to say more than 6".

The tranfer case is a box attached to the rear of the tranny. The tranny output shaft spins the T case and the rear drive shaft, when engaged the transfer case transmits power to spin the front drive shaft. Hope this helps.
