Liberty Rider Serves Up a Smooth Ride (updated)

Liberty Rider, a suspension system invented by a team including industry veteran Sonny Dismuke, began to roll out in 2015. Less than 100 RVs are using it right now, and Dismuke and his team have kept the product under wraps for the past year-and-a-half due to a supply issue of quality springs from a manufacturer.

The problem was recently solved by locating a new supplier based in the U.S., with an expected re-release date, with new springs, of June 15.

Now Liberty Rider is planning to lock in a wide network of distributors for aftermarket sales.

Dismuke will be attending several rallies this year to demo it for interested customers, visiting the Heartland, Forest River, and Grand Design owner rallies. There, he will detail the results of his tests on it thus far. Hint: It’s impressive.

“I’ve tested (Liberty Rider) on my trailer, which I’ve always had the Trailair air ride on it, and it just blew it away,” Dismuke said. “I’m thinking, ‘Whaaat’s going on here?’ ”

He’s since put 22,000 miles on his company’s test trailer using the Liberty Rider.

Dismuke, once a Navy Special Forces captain on a river patrol boat in Vietnam, has a long history of perseverance. After the Vietnam War, he worked for Chevron as a construction supervisor, building pipelines, and later transitioned into establishing Toyota production systems across the U.S.

In 2000, he and his team started innovative pin box company Trailair before selling it to Lippert Components.

From there, the same group created the Fifth Airborne air ride pin box and Sidewinder pin boxes, as well as the Ground Control 12V leveling system.

Those parts were hits, and the reason is understandable. “I’m an RVer,” he said, matter-of-factly. “When I travel, my wife gets really upset with me because I’ll just walk the campgrounds talking to people to find out what they want. And then I’ll design it, build it. But the biggest change in the whole industry was the Correct Track alignment.”

Here’s how the Liberty Rider supplies a smooth ride: When a tire hits a pothole, it pushes the spring up, and slips in and out of shock absorbers and the center bracket (the goldish plates in the image), completely diffusing the force from the spring.

Normally, when RVers apply the brakes, the axle wants to twist. Doing that increases the pressure on the front axle and decreases on the rear axle, and the result is “a braking axle and a smoking tire.”

However, with Liberty Rider’s center slipper spring attachment section, the front and rear axle are independent from each other. Even more, when the spring hits the axle, the bearing – affixed with a NeverFail bushing – rolls back and reduces the impact.

“(My trailer) runs the same loaded and unloaded because the springs dissipate the spring rate,” he said.

It’s an improvement from his past Trailair pin box invention.

“The Liberty Rider makes everything ride perfectly smooth,” he said.
