Before
Lifting or lowering a truck can sometimes take all day, get pretty costly, and require help from friends. For all of you truck owners with torsion-bar front ends on '88-'08 Chevy/GMC, '02-'05 Dodge Rams, and '97-'03 Ford F-150 trucks, there is a quick and easy way to lift your rig up to 3 inches or lower it down 2-1/2 inches. Suspension Maxx has released a special torsion key with an adjustable cam inside the key for rotating the torsion bar and altering the suspension height.
The added benefit of the Suspension Maxx design is the factory-like ride quality, strength from the 4140 heat-treated alloy keys, and seven selectable ride height options. Marked with indicators inside the key, the cam can be placed in different locations to adjust the ride height.
After
For this story, we tracked down an '04 Chevy Silverado 4WD and added 3 inches of ride height to the truck. Out back, a small-block kit leveled the truck out. Check out the images for a detailed depiction of the install.
Included in the Suspension Maxx kit was the adjustable torsion key, cam, and instructions. | 
Made out of 4140 heat-treated alloy steel, the Suspension Maxx torsion keys are stronger than the factory units. | 
Here, you can see the slide sleeve that keeps the cam from moving. |
