Anybody try to swap in a driveshaft from a 2500+ pickup? I was changing the oil in my dad's 2500HD and I saw that the driveshaft was HUGE. Probably 3-4" in diameter. It looks like it would hold tons of power/torque.

I know they would be different lengths, but getting one shortened would be cheaper than buying a custom 3-4" driveshaft.


Just wondering.

Check to see if the bearing caps are the same diameter, and also if the yokes are the same size. If so, you're set.

I believe those truck driveshafts are heavier, though. Not really something you want on a performance car.

If you wanted, you could make almost any driveline to fit your car. They make 4.5" x.459 wall seemless mild steel tubing that fits trucks like a Mack Cement Mixer. Some of the later trucks/cars have drivelines that are aluminum or composite so the physical size is bigger but much lighter. The size of the driveline (wall thickness and dia.) and u-joints are engineered into the drivetrain. Would you rather have a driveline or u-joint break or have the teeth stripped off your pinion? Your messing with more variables than you think. There should be some good website (Dana-Spicer, etc...)that show the formulas for this. Shortening a driveline (economically) depends on the material of the driveline and what type of weld yokes are used. Some weld yokes are not resuseable but yes, it's still cheaper than building a new shaft. We used to charge 45.00 labor for a cut, weld & balance. More if parts like a new weld yoke is needed.
