cranking torsion bars 13 2500hd

[rockrv]

Would it do any damage to crank bars a few turns? I hate sitting low in front. Require alignment?

As long as its not excessive...I went either four or six turns on my 2012.

That ride height IS the height from factory , yes you need an alignment after stressing the torsion bars more than they are engineered

 

But have fun paying the price for the ""look " you want

Only going by what I've read here...as long as you do not go over 2 inches from stock height your truck should be fine. As said just make sure you get an alignment and your truck may ride a little rougher.

Have them set the truck to be within the preferred Z height then you will know that all the working angles of all the front end parts is good.

What do you mean Z height?

It's the front truck ride height , the term is "Z " height

 

Google is your friend friend !!! Lol

Z Height:

 

Z Height Measurement

Note: For vehicles equipped with torsion bars, check the Z height before performing the alignment.

The Z height dimension measurement determines the proper ride height for the front end of the vehicle. Vehicles equipped with torsion bars use adjust arms in order to adjust the Z height dimension. Vehicles without torsion bars have no adjustment and could require replacement of suspension components.

Note: Perform steps 3–9 for both sides of the vehicle.

1. Jounce the front suspension of the vehicle by pushing the vehicle down and lifting up.
2. Allow the vehicle to settle and take a measurement.
3. Point A is the contact surface of the steering knuckle for the levels.
5. Set the top edge of the level on the reference surface of the steering knuckle © and extend the level directly under the front end of the front attachment bolt of the lower control arm (A).
6. While keeping the level in contact with the knuckle reference surface, adjust the level up/down until the bubble indicates it is horizontally level.
7. Measure the distance between the center of the bolt and the top of the level for your first measurement
8. Keep the top edge of the level on the reference surface of the steering knuckle © and move the level directly under the rear end of the rear attachment bolt of the lower control arm (B).
9. Measure the distance between the center of the bolt and the top of the level for your second measurement.
10. Average the measurements between the step 6 and step 8.
11. Record the measurement.

1. For vehicles equipped with a torsion bar suspension, turn the bolt (1) that contacts the torsion bar adjusting arm as needed. For vehicles without torsion bars, replace worn or damaged components as necessary

Z Height Adjustment

The allowed measurements are 128–140 mm (5.0–5.5 in) with a preferred value of 134 mm (5.3 in) and a left to right difference value of 0 ± 12 mm (0.47 in). A good alignment shop would check this and adjust the front end within the spec then align. Higher than the allowed max value is where you can cause the vehicle to bottom over bumps and cause damage to the suspension components.

 

If you are going to try and turn the adjuster bolts up yourself then have it aligned, I would take the measurements before you adjust, go up say 3-5 turns then re-measure. If you are still within spec, you can go higher until you reach the spec limit. Jounce the front in between each adjustment and when you turn the bolts, jack the front of the truck up to take the tension and weight off the front end and the bars.
