Adjusting Your Torsion Bars

You should be aware of the possible side effects that can be caused by adjusting your torsion bars.  The author of this article or is in no way suggesting that you should adjust your torsion bars.  This article is  being provided as a informative guide only.  Height increases of approximately 2" can be attained by adjusting the torsion bars but only at  the risk of increased wear on suspension and  drive train components.  This could also void your factory warranty.  The author or assumes no responsibility for damages or injury that may occur if you should decide to attempt the process being described.

Before you start make sure you vehicle is parked on level ground and take a measurement from the bottom of the frame directly behind the front tire to the ground.  Do this on both sides of the vehicle and write the measurements down.
In order to safely adjust the bolts you must take most if not all of the weight off the front wheels of your vehicle.  I jacked my truck to the point where the wheels where just about to come off of the ground.  This will relieve most of the stress being placed on the torsion bars but it is also a good idea to lubricate the the bolts and nuts before turning them.  Use WD-40 or a similar lubricant.

Using a 19mm box wrench loosen the lock nut located on the top of the Torsion Bar Adjustment Bolt.  Loosen the lock nut a few turns.  See Figure 2 and 3.  Mark the head of the adjuster bolt head with a felt tipped pen so you can count the turns you put on the bolt.   Use a 19mm wrench or socket turn the adjuster bolt clockwise.  This will tighten the tension on your torsion bars.  The nut below the lock nut is welded to the cross-member so you don't have to worry about holding it with a wrench  Don't forget to count your turns.  Repeat this process on both sides.  I would start with about four turns
Figure 3
Lower your vehicle and drive it backwards or forwards about ten feet to let everything settle into place.  Take a measurement from the same location you measured from earlier and make sure both sides are the same height.  If the increase in height is to your satisfaction tighten the lock nut.  If the height increase is not enough give the adjuster bolt a few additional turns.  If you have any questions, comments or suggestions please feel free to email me
