It is really simple. By "cranking up the torsion bar" we mean tighten up the adjusting bolt.
Notice this will give you more height in the front, but it will cause slight more harshness in the front suspension. This only adjust the front.
The socket size is 15/16in. Or 23mm or 24mm.
Do both sides as equal as you can.
It may help to turn the bolt by taking off some of the tension off of the bars by jack up the truck by the frame so the wheels hang down, it gives you no reference where you are at with the height!
You may need to use WD40 on the bolt if it is to hard to turn.
And an Impact wrench will make easy work of it.
When done lower the truck and measure both sides of the truck to see if it is sitting level side to side, adjust if needed.
Then truck around the block to unsettle the suspension then remeasure!
You will need to get an Aliment done to the front end.
With stock Torsion bar keys/ Anchors you can tighten up all the way.
If need be you can buy Re-indexed/ lift Torsion bar keys. From www.ebay.com
They will give you more lift above what stock keys can.
When cranking up Re-indexed keys it is important you notice that the control arms has bump stops. Once you reach this point stop.
Also the Torsion bar will start bending. The bar is unsafe if bent. Keep it straight.
Notice this will give you more height in the front, but it will cause slight more harshness in the front suspension.
