The latest technology delivers a ride with less fatigue

Give transit riders or even luxury tour bus passengers the ultimate suspension for stability and comfort. Drivers and passengers alike instantly notice the difference. Drivers experience less fatigue and safer handling. The proven LiquidSpring™ smart suspension for bus applications offer superior advantages over conventional suspensions. Don’t just take our word for it.

The ultimate in driver and passenger comfort

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.

The bus rides more like a limousine now

I have well over 15 years of experience with commercial driving and have operated Class A trucks with doubles, Class B transit, paratransit buses, even up to super-stretch limousines. I have driven in virtually every type of driving condition on every kind of road and traffic condition.

With the LiquidSpring suspension, I have noticed a remarkable difference in how our bus rides. I oversee the bus and van transportation services for a Senior Living Community just outside of Modesto California. Modesto reportedly has some of the worst roads in America. Our new Starcraft Allstar 25 bus, with the LiquidSpring suspension, is among the very smoothest rides I have ever experienced. It rides more like a limousine than it does a bus. While traveling on the rural backroads, we frequently encounter bumps and potholes that made the ride of our old bus very uncomfortable. With the new suspension systems, passengers frequently comment on how smooth the ride is. They often say that the bus rides “like a charter bus.” We have experienced a remarkable increase in passenger satisfaction.

In our old bus, the noise and vibrations were so bad that passengers could not carry on a conversation. On one excursion, we traveled to Yosemite National Park. While on the twisty mountain roads, I was able to quickly switch the firmness of the ride to maximize stability and control, and then change back to Comfort Ride for a smooth and quiet ride.

While negotiating steep driveways and parking lots within Modesto and Turlock city limits, I have been able to quickly raise the ride-height to ensure adequate clearance, thus reducing the risk of dragging the exhaust or bumper. I have been thrilled with our new suspension system Travis. Thank you so much for the excellent customer experience!

Compared to the Original, LiquidSpring’s Bus Suspension is Like Night and Day

While it’s fresh on my mind – I rode this bus back home from Chicago last night after working at O’Hare since Tuesday. I deliberately sat over the rear axle to get the full effect of the ride quality. You can still feel bumps, but there is nothing excessive about it. We had a terribly rigid leaf spring on the stock chassis, and it was our number one source of rider complaints – probably about 90% of the legitimate complaints. I had one person across the aisle from me in my row, and one person on each side of the aisle of the row in front of me. All three were asleep most of the ride, with their seats reclined. I was able to comfortably work on my laptop and watch videos on my phone without any excessive jarring. The difference between before/after the installation has been like night and day for us. Not one single person has complained about the ride since installing the Liquid Spring suspension. With the original suspension, it was nearly impossible for me to get any work done on my laptop without accidentally hitting keys or clicking buttons. We couldn’t be more pleased with the improvement we’ve seen. It’s not a cheap system, but it has been very much worth it for us and our particular usage of the vehicle.

Pain-Free Transportation Helps Seniors Focus on Fun

testimonial-bluffsThanks for the great service and the wonderful new system. As Community Life Director for a large luxury retirement community, I plan many outings using the bus we recently purchased. Many residents stopped signing up for the trips as our bus had a basic suspension with a very rough and violent ride. Residents as well as myself complained of body pains and discomfort even on the short rides.

During our initial meeting when you assured us an improved ride quality, I wasn’t sure you would be able to pull it off since our ride was so bad. Your team has completely made a believer out of me and our frail residents. Our newly installed LiquidSpring™ system has surpassed all expectations and we are all delighted with such a smooth and comfortable ride. It is evident from the residents smiles and hearty conversation. They can now focus on having fun as they travel to their next destination! Thank you again for your expertise in engineering as well as excellent customer service. We are 100% satisfied! Again, thanks for everything.”
