This innovative spring system improves your RV handling

While it’s become standard equipment on many emergency vehicles, the LiquidSpring suspension system also improves RV handling. This might sound like an advertisement, but it actually follows up on a recommendation from a tech-savvy buddy, who had a LiquidSpring system installed in his Class C.

Talking with Carl Harr, head of sales for LiquidSpring Smart Suspension headquartered in Indiana, it turns out that the system installed in RVs is already standard equipment on more than 95 percent of ambulances and other emergency vehicles.

A further qualification: Tiffin, Fleetwood, Southwind and Phoenix Cruiser offer it as an option on new Class A’s and C’s, according to Harr. It comes at a hefty price, but apparently RVers find enough benefit to make the outlay worth it.

Again, it may sound like a puff piece from the company, but the friend who put me in touch with Harr is a firm believer. Harr explained that LiquidSpring is an active suspension system that improves handling and safety by monitoring steering, speed and height, which eliminates sway movement.

Another benefit is reduced vibration that causes wear on vehicles. The vibration is absorbed in silicon fluid that has 6 percent compressibility. The sales head claims that the system consumes less energy to operate due to the LiquidSpring pump only operating for 5-15 seconds as opposed to an air suspension compressor operating 2-3 minutes, which also reduces wear and tear on components.

It is being installed in Class A, B and C RVs but isn’t for tow-behinds. The cost sounds quite pricey, $10,000 to $14,000, depending on the size of the rig, but it’s the value that brings in customers.

Started as a mining equipment company, seven years ago LiquidSpring expanded into on-road vehicles, including ambulances and school buses. More information about the company and suspension repair shops that can do the retrofitting is available on their website.

I have had the liquid springs system on my Born Free Class C coach for over 5 years. It is the reason I bought the coach after test driving one with it installed. The ride and handling with this suspension is fantastic when compared to a stock Ford E-450 chassis or even one modified with premium suspension components. The article is no “puff piece” from this company. An added side benefit to the ride and handling is the ability to raise and lower the rear of the coach about 6 inches from level. As a result I do not drag the rear of the coach when entering a steep driveway. I have also found that I rarely have to use blocks to level the coach as most RV sites are off level from front to back rather than side to side. In addition I have found their customer service to be exemplary. If all RV builders and parts suppliers had their customer service philosophy Chuck would lose one of his primary topics to write about.

I join you in this. Our 2014 Born Free also has Liquid Springs. They automatically adjust to road conditions (due to the fact they are designed for smooth rides in heavy Emergency vehicles where a patient needs to be as level and not jostled about, like going over railroad tracks or rough roads). Also great for entering or leaving the entrance/exit of a gas station, where the entry is too steep for the rear end of most RV’s. With Liquid Springs you just push the up button and the rear of the vehicle is raised up.

Not enough money left after you install this thing.

Yeah, after installing this you’ll have no worries about road handling because all you’ll be able to afford is a staycation in your driveway.

Yes I agree, it sounds like a puff piece from the company. 😁

HWH has had “active air” on coaches for years. Their system uses your existing air bag system and constantly monitors road height and level conditions and adjusts the air bags automatically keeping the unit level around corners, curves and quick lane changes. Works really well. we had it installed on our old Mountain Aire Motorhome. 15yrs ago it was $8000 installed.
