Shuttle/Limo Bus and RVs

One of the challenges in designing a vehicle to transport people is to provide a comfortable ride while maintaining the load-carrying capacity needed. What if your suspension system could automatically adjust itself to provide the optimum balance, even accommodating a change as small as when just one person enters or exits your vehicle? The R4Tech Suspension system can!


Better Ride Quality | The use of air springs and load-adaptive shocks allows the R4Tech Suspension system to provide the needed load-carrying capacity with the softest ride possible. The system uses height-control valves to sense changes in weight and quickly adjust the system. Your passengers will appreciate the improved ride quality.

Improved Vehicle Control | The R4Tech Suspension system controls the axle much better than the factory system, greatly reducing wheel shudder, improving braking efficiency, and providing better traction during acceleration. The self-leveling feature maintains front suspension geometry for improved handling.

Kneeling On-demand | This system allows you to lower the rear of the vehicle up to six inches* on demand. Even when fully loaded, the system can return the vehicle to normal ride height in seconds. This feature is also extremely helpful when connecting a trailer.

Cost Savings | Depending on your driving habits, you'll also see a fuel savings** because the R4Tech Suspension system weighs less than the components it replaces.

Durability | Our system is designed with the same tools and standards used by the original vehicle manufacturer. We use a range of computer-aided engineering (CAE) tools as well as real-world testing to ensure that our system will serve you dependably every day.
