Suspension Maxx Offers an Adjustable Torsion Bar Lever to Level Lift Your Chevy Truck or SUV

Level lifting the torsion bar-equipped GM trucks is a fairly simple modification. Traditionally a person has had two options for raising the nose height of GM trucks that possess a torsion bar front suspension. These models include 4x4s from 1988 on up as well as 2500 and 3500 98-up two wheel drive models. Tahoes, Suburbans, Escalades and even Hummers also fit into this same category. The options for leveling usually involved either cranking the torsion bar lever bolt up in order to twist the bars and consequently increase the front suspension ride height. This method, though visually appealing, has many functional drawbacks. Generally the added tension on the torsion bars makes the ride very stiff.

A substitute option has been to install a "leveling lever or key". These are levers that reposition the torsional location of the bar in order to achieve the desired ride height while allowing the lever to reside in a near stock position in the torsion bar cross member. But one of the drawbacks of this type of lever is basically the height you get is what you get with the lever. It isn't adjustable aside from repositioning the lever, which in the end can affect the vehicle's ride.



Suspension Maxx has a great new torsion bar lever called the Maxx Cam 2 that is basically an all-in-one lever that can raise, or even lower the truck per the height the owner wants while allowing the lever to be positioned in a factory setting. The Maxx Cam 2 features seven selectable ride height positions that can lift the front of your truck up to 3 full inches or lower it 2.5 inches with virtually no loss of ride quality. A guide is provided with each kit which describes what position to place the interior cam in order to achieve the desired height adjustment. The two-piece design allows the installer to calibrate the Maxx Cam to compensate for torsion bar sag from added equipment such as heavy bumpers, winches, snow plows or any reason increased suspension height is needed.

If you are looking for a great new way to level your truck, then the Maxx Cam 2 could be what you are looking for. The piece of mind of knowing you can alter the height without having to buy another product is priceless! Installation is easy and requires the vehicle be aligned afterwards. This product doesn't increase the load carrying capability but does Suspension Maxx does state that it does add suspension travel. To document the installation of the Maxx Cam 2 kit, we visited the suspension authorities at So Cal Supertrucks in San Bernardino, California where the kit was installed on a 2006 Chevy 2500 HD. In this installation we used another one of Suspension Maxx new products; the Super T Maxx Torsion Bar Tool which is universal for most makes and models of trucks and makes removing the torsion bar levers much easier.

The first step in the installation was to put the truck on a lift. For this particular operation we rolled the truck up onto one of So Cal Supertruck's alignment tables where the conversion and alignment could take place without having to move the truck around. Prior to beginning installation, a measurement was taken of the unaltered ride height by measuring from the table to the bottom of the fender lip.	The measurement was 36.75 inches and documented as such to compare with the lift achieved once the Maxx Cam 2 installation was complete.	Next step is to unbolt the upper shock mount hardware.
	The lower shock mount bolt is also removed so the shock can taken out.	The reason for taking the shock out is that Suspension Maxx includes a shock spacer that installs onto the upper mount stem. This effectively and minutely increases shock travel which is better suited for this type of level lifting procedure.
With the front lifted up on the table enough to allow the suspension to hang at full droop, an 18mm socket and impact gun are used to remove the torsion lever bolt.	Remove the bolt and place close by as the same bolt will be re-installed with the Maxx Cam 2 lever.	Suspension Maxx offers the Super T Maxx torsion bar tool which is designed to handle the force of compressing the lever up into the cross member so the horizontal adjusting nut can be removed.
The horizontal adjusting nut slides out from the side of the cross member as shown.	The Super T Maxx tool was then removed to allow removal of the factory torsion lever. In order to remove the lever, you will have to slide the torsion bar forward slightly.	The Maxx Cam 2 is an innovative way to level your truck. The torsion bar hole is keyed into the center cam in a manner which allows the owner to determine how much height adjustment he or she wants.
One side of the cam is labeled "A" and the other is labeled "B". Each cam tooth indention on the level has a number. By looking over the provided position guide from Suspension Maxx, the right position can be determined and the cam placed appropriately into the lever as shown. For this installation we were looking to get roughly 2-inches of lift. The tallest increase on the chart for the 2500 is listed as 1.75-inches with the lever set at the stock position. We installed the cam at the B1 setting.	Before installing the Maxx Cam 2, we took the opportunity to place the factory lever next to the Maxx Cam 2 to illustrate the differences. The most important element to note is that with the torsion bar insertion hole lined up on both levers, the adjustment arm of the Maxx Cam 2 is downward instead of level like the factory lever.	The Maxx Cam 2 lever installed into the torsion bar cross member in the same manner in which the factory lever was removed.
The Super T Maxx tool is then installed over the cross member with the jack screw pressed into the indention in the lever arm. Using the impact gun, the lever arm is raised upwards.	With the lever raised up enough, the factory horizontal adjustment nut is inserted into the cross member. This nut is what the lever arm rests on when the tension from the tool is released.	Before installing the factory torsion bolt, some anti-seize grease is applied to the threads.
Thread the bolt into the horizontal nut to the point the head of the bolt just begins to touch and lift the lever arm.	Lower the front suspension back down to the new ride height and then check the upper control arm frame bump stop to make sure there is adequate clearance between the stop and the bottom of the control arm. Around 3.4-inch gap is sufficient, but you don't want any less gap than that.	This photo illustrates the shock spacer installed at the beginning of this article. The spacer extends the shock about ½-inch more than in the stock configuration, which in turns allows the shock to work more efficiently and not top out when the suspension is at full droop.
For the last and equally important step, SoCal Supertrucks dialed the alignment back in using their Hunter equipment.	Measuring the front end height afterwards we achieved just over 2 inches of lift at the cam setting we chose. Once the suspension settles in after driving a bit, we expect the height will come down to almost what the Suspension Maxx guide stated that cam position would be in terms of achieved lift.
