Torsion Bar Adjustment

What's the deal with adjusting the torsion bars on the front of the truck? I want to take the rake out of the DMAX, but the dealer said if you crank those dudes up you have to realign the front...What are the advantages/disadvantages of doing so? I'm not running huge tires, nor do I want to. I run 265/75/R16's which are fine for my driving. Also, aren't there kits available for the front end lift? Are these difficult to install? Where can I get one for reasonable? Looking for any useful info on the subject----Thanks.

You will have to realign it if you go very far say more than 1.5" . The only advantage is its free. Except for the alignment. Disadvantages-If you crank them all the way up you will have to get longer shocks or shock extender brackets($30) to keep from running out of down travel on the shocks. You will also were your ball joints out a little quicker.
I cranked mine up and its fine It will ride rougher if you dont extend those shocks.

It's really simple. First get a tape measure and measure from the bottom of your wheel to a fixed point on the fender at the bottom of the wheel opening. Write this measurment down do it on both sides. I did mine in my driveway so I just got my floor jack and lifted one side at a time.Lift one side up make sure that you are lifting in a spot where the wheel is allowed to drop and extend(such as the frame and not under the lower control arm)this allows the torsion bars to relax a little bit making it easier to turn the bolts.Oh also I would spray some penetrating oil on the bolts before hand. If you dont know where the torsion bars are look for a really long round bar that goes to the lower control arm all the way back to a cross member almost halfway back the truck. At that cross member you will see a bolt(18MM I think)that goes up to press on a key that
turns the torsion bar. Tighten that bolt how ever many turns you want to just do the same on both side. This will increase the preload on the bars raising the front up. Let the truck back down and measure at the wheel again to see how much you raised it. Its not uncommon for one side to be a little lower than the other from the factory(I think driver side lower).Remember to get an alignment and be careful use jack stands and dont try remove anything those torsion bars are under EXTREME pressure.

Yup exactly what wild turkey hunter said!!

It does look cool on your truck but you will need a aligment. It could also weakin the torsion bars due to the load. The biggest thing you gotta watch out for is if you pull a heavy load in 4wd with your truck you can break the tie rod ends real easy. My buddy was pulling his jeep up a stone road with his dmax and you could watch the tires shake when he got on it. This happend alot to people that truck pull. The fix for that is tie rod sleeves.

Do both adjustment bolts have to be at the same level? My driver side is cranked in way more than the passenger side.
