CAB/SLEEPER MOTION CONTROLS
	Flat Top	DV3-3045
	Mid Roof	DV2-3050
	High Condo	DV1.5-3055

The Cab/Sleeper Motion Controls check the side-to-side rocking of the sleeper and the bouncing at the back of the sleeper. How does this help you? You will not have to fight the steering wheel to keep the truck straight in cross winds. Your co-driver will be able to sleep better and not have “to hang onto the edge of the bunk” to keep from falling out. Your belongings will “stay put” in the bunk. It’s even easier to cook while rolling down the highway. As one customer with a big condo said, “my eggs stayed right in the frying pan!” You’d be surprised how much of the movement you feel at the steering wheel comes from the excess movement of your sleeper. The Cab/Sleeper Motion Controls can take most of that motion out. Cab/Sleeper Motion Controls install in the air line directly below the air spring. They never need replacing and are self-regulating. They are calibrated at the factory but different control levels are available.

Is your seat bottoming out? Is vertical seat travel taking it’s toll on your back and legs? There is something you can do about it. You can “tame” that seat movement by installing our Seat Motion Control in the air line next to the air spring. By reducing the air spring bounce, we reduce excess vertical bounce and back slap in your seat. You use 50% less air but stay comfortably in the mid range. We even calibrate the motion control according to your height and weight to give you a customized ride. Every driver and every air seat can benefit from the controlling action of the Seat Motion Control. Seat Motion Controls install in the air line directly above the air spring. They never need replacing and are self-regulating. They are calibrated according to the height and weight of the driver and passenger but different control levels are available.

The Drive Axle Motion Controls greatly reduce the bounce and bogey-hop of your drive axles. We do this by installing them directly into the suspension air springs. By controlling the movement of the air springs, we control the drive axles. What this means for you is a much smoother ride. Not only will you feel the difference at highway speeds, but in crossing railroad tracks, or pulling a tanker, car hauling, etc.. Our Drive Axle Motion Controls make a major contribution to improving the overall ride of your truck. If you have an air ride trailer, the Trailer Axle Motion Controls are just one more way to improve your overall ride. A trailer that is bouncing and swaying less means a truck that is easier to drive. Drive Axle and Trailer Axle Motion Controls install directly into the suspension air springs and never need replacing. They are self-regulating. They are calibrated at the factory but different control levels are available.
