i have an 84 totota pickup i have been working on every now and then i was just wondering how big of a lift can u put on it untill u have to buy longer driveshafts?

 

My buddy just lifted his 83 about 2.5 to 3" and his front drive shaft would not even reach together. the rear you should be able to get a few more inches out of.

 

I have 4 inches of lift on my 84 and no problem with the length of my driveshafts, have never had one slip out while wheelin.

 

Actually after some more thought i know for a fact they run different rear driveshaft set up on the extra cabs, they put in a carrier bearing to bring the shaft back further up near the body before coming down hence lowering the distance it travels.

As for front shafts they may have switched to a longer one between 83 and 84, all i know is my 85 has a longer front driveshaft than the 83. haha, hmm that wasn't much help, but sounds like you can fit 4" though

 

A lot depends on the type of lift spring. When I put on an off the shelf 3.5" lift spring, I had no issues with drive shaft length. But when I reworked the springs for more flex and especially when I moved the front axle forward about 3/4", I had to get the front shaft lengthened. A drive shaft spacer is always an option if you need to make the shaft just a little longer:

Not all extra cabs have the carrier bearing some just have a regular 1 piece shaft.

I have a 4" pro comp lift and I have no issues, but like Crawler said if I was to move my axle forward things would be different.

 

wow, that seems pretty weird. why would they do that? thanks for the correction man.
