RAM Heavy Duty. Built To Adapt.
Big loads. Long distances. Changing conditions. LiquidSpring gives RAM Heavy Duty owners an active suspension system designed to adapt as the truck's job changes.
Whether you're towing, carrying a heavy touring setup, building an adventure truck or using your RAM across changing payloads, LiquidSpring replaces the compromise of a fixed-response suspension with an integrated active hydraulic system.
LiquidSpring applications are available for selected RAM Heavy Duty platforms. Final compatibility depends on model year, chassis, drivetrain, rear-wheel configuration, modifications and intended use.

Heavy Duty When You Need It. Comfort When You Don't.
A RAM Heavy Duty is built to work hard, but that doesn't mean it operates at maximum payload every day. LiquidSpring is designed to adapt as the truck transitions between towing, carrying, touring and everyday driving.
Built For A Truck That Does More Than One Job.
Traditional heavy-duty suspension is often designed around a particular load or operating condition. LiquidSpring takes a different approach, continuously managing suspension behaviour as the truck, payload and driving conditions change.
Heavy Payload
Designed to respond as equipment, touring gear and vehicle payload are added to the RAM platform.
Towing
Helps manage vehicle movement and suspension response during demanding towing and long-distance touring applications.
Unloaded Driving
When the weight comes off, the system can adapt again instead of leaving the truck locked into one heavy-duty suspension feel.
Adventure Builds
Suitable applications can benefit from adaptive response, ride-height control and controlled articulation beyond the road.
Changing Payloads
Suspension behaviour can adapt as the truck transitions between light and heavy operating conditions.
Towing Confidence
Designed to help provide a more controlled and composed platform while towing caravans, trailers and heavy loads.
Everyday Comfort
When the truck isn't carrying its maximum load, the system can adapt to suit more typical everyday driving conditions.
Long-Distance Touring
An adaptive suspension platform for RAM builds that spend long hours travelling with changing road and load conditions.
Monitoring Vehicle Inputs Every Second.
LiquidSpring continuously evaluates vehicle inputs and uses onboard control to adjust suspension behaviour as operating conditions change.
Find The Right System For Your RAM.
LiquidSpring is available for selected RAM Heavy Duty platforms. The correct application depends on your exact truck, model year, chassis configuration, rear-wheel setup, existing modifications and how the vehicle is intended to be used.
RAM 3500
LiquidSpring applications are available for selected RAM 3500 configurations, making the platform suitable for demanding towing, touring and heavy-duty vehicle applications.
RAM 4500
The RAM 4500 provides a heavy-duty cab-chassis foundation for specialist bodies, touring configurations and adventure builds where payload and vehicle use can vary considerably.
RAM 5500
Selected RAM 5500 cab-chassis applications can be equipped with LiquidSpring for serious heavy-duty, expedition and specialist vehicle builds.
Build The System Around The Truck.
LiquidSpring systems are offered in different configurations depending on the RAM platform and intended application. This allows suitable trucks to retain a more conventional vehicle height or form the foundation of a more extensively modified adventure build.
Stock / Levelled
For selected applications where a more factory-style vehicle height and stance is preferred.
Application Dependent2" Configuration
Raised LiquidSpring configurations are available for selected RAM platforms and vehicle applications.
Application Dependent4" Configuration
Selected RAM applications can support higher configurations suited to more extensively modified adventure builds.
Application DependentLiquidSpring applications are available for selected single-rear-wheel RAM configurations.
Dual-rear-wheel and selected conversion applications may also be supported depending on the exact RAM platform.
Tell Us About Your RAM.
A RAM model designation alone is not enough to determine the correct LiquidSpring system. Model year, chassis configuration, wheelbase, drivetrain, SRW or DRW setup, existing modifications and intended vehicle use can all affect compatibility. LiquidSpring Australia will confirm the appropriate application before proceeding.

Build The RAM You Actually Need.
A RAM Heavy Duty can be a tow rig, touring platform, camper base, work truck or adventure vehicle. LiquidSpring gives suitable applications a suspension system designed around changing conditions rather than one fixed setup.
Heavy Duty Capability. Adaptive Suspension.
The goal isn't simply to make a RAM softer or taller. It's to create a suspension platform that can respond as the vehicle transitions between different loads, road conditions and operating requirements.
Tow Rig
For RAMs regularly towing caravans, trailers and heavy equipment.
Touring Build
For long-distance vehicles carrying changing touring loads.
Adventure Truck
For heavily modified RAM platforms travelling beyond the bitumen.
Specialist Vehicle
For cab-chassis and custom builds where vehicle load and purpose vary.
