Several companies used January’s 2017 Florida RV SuperShow to gain added exposure within the RV community, including Liquid Spring LLC which touted its “Compressible Liquid Adaptive Suspension System” (CLASS) during the four-day event at the Florida State Fairgrounds in Tampa.

The Lafayette, Ind.-based firm forged a partnership with Born Free Motorcoach out of Humboldt, Iowa, three years ago, but is looking to significantly grow its market share. Currently an option on Born Free units, Liquid Springs has developed an application for gas Class A’s on the Ford F-53 platform, as well as the Class B and C segments, and is looking to spread further into the RV industry.

Carl Harr, director of sales and marketing for Liquid Spring, was on hand in Tampa to explain the company’s chassis suspension technology, which uses a compressible silicone-based fluid with a 6% compressibility aspect.

“It replaces and eliminates leaf springs and shock absorbers, and in just five years it’s already used on 98% of all North American ambulances,” Harr said. “The technology we use looks at steering, speed, brake, and height control information to control what spring rate is employed. Additionally, CLASS automatically ‘load levels’ chassis to compensate for load imbalance due to variations in payload distribution.

“So, as you’re driving down the road and you induce an evasive lane change on the steering, the suspension can ramp up the spring rate to reduce body roll. As soon as that event is over, it goes back to a soft spring to give you a soft, comfortable ride.”

Harr noted the company has conducted tests on a Liquid Spring-equipped F-550, with the result being a 53% reduction in body roll and 45% reduction in vibration.

Harr said Liquid Spring engineers will partner with OEMs, providing the CAD data for the layout of the suspension so it can work within their floorplans and be a seamless installation at the factory.

Liquid Spring was founded 20-plus years ago, initially serving the open-pit mining equipment industry before progressing to on-highway vehicles. Today, it operates out of a 50,000 square-foot facility producing 2,500 suspensions each year.
