Steer Axle Stabilizers

That’s what Donvel is all about. The Donvel Ride Control System reduces the bounce, rock and roll in your truck (Class 6, 7, 8). Air ride suspensions are great, but they bounce and rock, overreacting to the bounce and roll especially at highway speed and in the wind. Donvel uses air units that are being controlled in milliseconds using DVI Motion Controls. This gives you a totally different approach and solution to many of the bad effects you are feeling on the highway.

So what does this mean to you?

Greater ride safety and stability
Less physical pain and fatigue
Reduced maintenance costs

How do we do this? By using Steer Axle Stabilizers as the first line of defense against bounce and sway and then using the DVI Motion Controls to finish the job by reducing the bounce and sway of the existing air springs on the cab and sleeper, seat, drive axles and trailer axles.

The Steer Axle Stabilizers with DVI Steer Axle Motion Controls are the first to react to all road conditions.

How do the Steer Axle Stabilizers solve the problem of rock, roll, dip and snap? They are air units that are being controlled in a millisecond. But how are we doing this? We insert a DVI Motion Control in the air line at the top of each air spring. By doing this, we move beyond just air ride to the next level of air controlled ride.

You adjust the pressure needed for each load balance, fifth-wheel setting and trailer axle setting. We build internally how fast the units are reacting to the pressure the driver gives them. The Steer Axle Stabilizers react to each bump by holding and releasing instantaneously reducing the over compression and snap back of the leaf springs. This controls the steer axle and flattens the bump and reduces back slap, body roll and road walk.

In addition to reducing bounce, the Steer Axle Stabilizers control sway. If your truck hits a pot hole, the Stabilizers will compensate for it instantly. If you are leaning in the corners, the Stabilizers will work against that lean.

What all this means to you is a truck that travels straight down the road, with greatly reduced shock and vibration to the truck and yourself. The steering wheel will shake less in your hands. Your ride will be less painful and tiring. Your dash will vibrate less. You will be able to turn corners more safely. You won‘t have to fight the steering wheel to stay in the road. Your shock absorbers will last twice as long. Your tires will wear longer with less dipping.

Driver adjustable gauge and valve. Bezel Opion. As one of our customer’s said, “We are not exhausted anymore. My wife and I are not oversteering anymore, constantly correcting the truck. I used to get mentally tired focusing on keeping the truck in the road. I can think about other things now because it‘s so easy to drive. It’s an amazing transition. My coffee doesn‘t spill.” ( J. Hill, Mesa, AZ)

Control is the key to improving your truck’s ride and handling.

The Steer Axle Stabilizers are custom-built for each truck to ensure a good fit and factory appearance. They are shipped assembled with every part included for self-installation and come ready to bolt on. The Steer Axle Motion Controls on the Steer Axle Stabilizers are calibrated at our factory, but different levels of control are available. You can adjust the air pressure from the dash as the road and load changes. A bezel is also available for under dash mounting of the air gauge and valve. Because some older trucks may have had suspension changes, we have a measurement sheet (PDF format) available which will help us build specifically for your truck. Just print it, fill it in and fax it to us at (903) 845-2562.
