You won’t believe how much easier it is to drive

This is the Suspension with CLASS®

Compressible Liquid Adaptive Suspension System

LiquidSpring is a smart suspension system for ambulances, shuttle buses, RVs, school buses and work trucks. Liquid-based struts and an onboard processor provide better handling and control when you need it, and a smoother, softer ride when you want it. The reduced vehicle vibration increases comfort and can also lower maintenance costs. In short, we named our company LiquidSpring because it is the heart of our system, a shock-absorbing liquid, enhanced with smart controls to bring you the right sized spring for every moment, instead of a one-size-fits-all metal spring solution.

Tiffin’s Allegro 34 PA gasser closes in on the panache of a diesel pusher with the optional LiquidSpring suspension upgrade.

Fortunately, gas-powered motorhomes no longer take a step back from the luxury and livability once only found in more expensive diesel pushers.

Add on the optional LiquidSpring Compressible Liquid Adaptive Suspension System upgrade for the Ford F-53 chassis right from the factory and ride quality becomes comparable to entry-level diesel pushers with air springs.

Don’t Just Take Our Word For It

See what others have been saying about LiquidSpring suspension.

The motorhome itself seems to be much more stable

Even though I was only able to drive the motorhome a short distance from LiquidSpring back to Dynamax in Elkhart, Indiana I wanted to let you know how much better the unit rode and drove. It felt like the sting we were receiving from expansion joints and bridge joints has been controlled and lessened considerably. And, as you indicated the motorhome itself seems to be much more stable when turning, changing lanes, etc. I look forward to putting more miles on the unit to see how it performs under many different conditions, but my first impression is that it was much improved. Thank you for all your help in arranging this addition to the rig.

Update: We have now had a chance to put about 1000 miles on the motorhome and the suspension has been terrific! The ride is much more comfortable and controlled and the impact with potholes and expansion joints is so much easier on the motorhome and passengers. Thanks for a great product!

The only way to improve it is to drive a hovercraft

We had the Liquid Springs system installed on our 2016 Tiffin Allegro 36la motor-home at Henderson’s Line up in Grants Pass, Oregon. I will get the hard part over with first……COST! Our bill for the modification was $13,100.65. No State tax in Oregon helped a little!

Since picking up our unit we have driven from Grants Pass, Oregon to Bakersfield California, 623 miles of varied road conditions. So I think we have given the system a fair trial. We immediately noticed a great improvement when crossing bridge decks on the interstate, what had been bone jarring impacts on many bridges were smoothed out to the point that we barely noticed crossing the bridges. The ride was also smoothed out on sections of concrete highway that in the past we had found to be a very rough ride. However, there are sections of highway, particularly in California where we still felt jarring hits when we hit sections of concrete that had cracked and sunk or were potholed. I think the only way you improve on that is to drive a hovercraft! I had wondered when I would use the “Sport” setting. Well coming through the mountains towards Shasta Lake in California, there are some very sharp curves that in the past I have found challenging. In the “Sport” mode the motor-home suspension really tightened up and I felt very comfortable negotiating the curves. Overall, we are very happy with the system. Was it worth the cost? That is obviously an individual choice. I am in the happy position that I can afford to pay for this system and I have no regrets………However, it is not perfect and on particularly bad sections of road you can still feel some jolting hits, albeit not as bad as they were before we installed the system.

I hope this has helped anyone who is considering this system.

Purchasing our class A motor home no longer feels like a mistake

I wanted to report in that we had a delightful trip home last Friday. We didn’t notice semi trucks or cars passing, barely noticed any roughness going over bridges or rough highway, and the 4 hour drive was really relaxing for Ron. All just like you said it would be! The LiquidSpring suspension is amazing. We no longer feel like we made a mistake purchasing our class A motor home. We will be in touch in a few months to see if the front suspension is available.
