Torsion Bar Crank

The torsion bars on our crew cabs are simply explained as the device that controls the I.F.S. to move in vertical directions by twisting steel. You can adjust the torsion bars at the cross member under the truck right where the 2 doors meet.

So to add up to 2" of height to our crew cab, you can tighten these up, thus lowering the wheel down from its standard riding position. Only do this mod if it is right for you. There are always negative affects to everything. It is a common problem for cv boots to wear out fast. Also, the ride will stiffen. YOU MUST GET AN ALIGNMENT!!!! after this is done! If you mess with your torsion bars, you have just messed up your alignment and it will eat your tires fast if you don't get one soon! A common modifaction to do with this, would be to add shackles or to do an add-a-leaf.


  1. Measure the distance between the ground and the fender after parking on a flat surface. Mine was was 33.5"
  2. Measure the distance between the top of tire and the fender. Mine was 6.5"
  3. Then jack the truck up evenly and always use jack stands.
  4. Measure the distance between the top of tire and fender again. I think mine was 9.5" (not sure)
  5. Now with an 18mm socket, turn the adjustment bolt clockwise. I did mine 3 revolutions for a 1" lift. The amount of turns is up to you. Keep track of your turning! Some people say that you can see the wheel lowering, but mine didn't, even after i measure it, it didnt move. Also, it is normal to have one side higher than the other, I had to crank on my passenger side 3.5 turns to make it even.
  6. So I lowered it down and walla, I had a 1" lift in the front. Now the truck will settle a 1/2" or so after a few bumbs in the road. So actually as soon as I had mine down, it was an 1.5" but it settled to an inch.
  7. Measure the distance between the fender and the ground and the top of the tire again. My new height was 7.5" from fender to tire and 34.5" from ground to fender.
  8. Get an alignment!
