RoadActive Suspension is a mechanical suspension support system designed to reduce rear-end sag, improve towing stability and enhance the handling of compatible leaf-sprung Ram 2500 and Ram 3500 trucks.
Whether you own a Ram 2500 or Ram 3500, this guide will help you select the correct RoadActive Suspension kit for your vehicle and application.
RoadActive Suspension works with the existing rear leaf springs to provide progressive support when towing or carrying a load. Unlike airbags, there are no compressors, airlines or regular pressure adjustments required.
Ram 2500 and Ram 3500 trucks are commonly used for demanding towing and load-carrying applications. RoadActive Suspension helps support the rear leaf springs while maintaining normal suspension movement for everyday driving.

The Heavy Duty kit is designed for Ram 2500 owners towing heavier trailers or carrying regular loads. It provides additional rear suspension support while improving stability and control.
The Heavy Duty kit suits demanding towing and load-carrying applications where additional rear suspension support is required without stepping up to the Mega Duty system.
Mega Duty provides the highest level of RoadActive Suspension support available for compatible Ram 3500 models. It is intended for the most demanding towing and constant-load applications.
These RoadActive Suspension kits are designed for compatible leaf-sprung Ram 2500 and Ram 3500 models only. They do not suit coil-sprung Ram 1500 models. Some newer Ram 2500 models also use coil rear suspension and are not covered by the products shown on this page. Always confirm the rear suspension type and product fitment before ordering.
Choose the Ram 2500 Heavy Duty kit for compatible 2003–2014 leaf-sprung models used for caravan towing, canopies, work trailers, commercial use or regular load carrying.
Choose Heavy Duty for general heavy towing, large caravans, horse floats, work trailers and vehicles carrying moderate to heavy constant loads.
Choose Mega Duty for the most demanding applications, including heavy fifth-wheel towing, truck campers, substantial constant loads and severe commercial use.
The Ram 2500 Heavy Duty kit shown on this page suits compatible leaf-sprung 2003–2014 models. It does not suit later coil-sprung Ram 2500 models. Confirm the vehicle year and rear suspension type before ordering.
Compatible leaf-sprung Ram 3500 models from 2003 onwards are available with either Heavy Duty or Mega Duty RoadActive Suspension. Select the kit according to the load, towing requirements and product fitment.
No. The products shown on this page do not fit coil-sprung Ram 1500 models. RoadActive Suspension requires a compatible rear leaf spring suspension system.
Many newer Ram 2500 models use coil rear suspension and are not compatible with the leaf-spring RoadActive Suspension kit shown here. Check the rear suspension type before ordering.
Yes. RoadActive Suspension helps reduce rear-end sag, control suspension movement and improve stability when towing caravans, fifth wheels, horse floats and other heavy trailers.
No. Mega Duty is designed for the most demanding applications. The Heavy Duty kit may be the better option for general heavy towing and moderate constant loads.
RoadActive Suspension provides mechanical suspension support without airlines, compressors or pressure adjustments. Whether it replaces an existing airbag system depends on the vehicle and how it is used.
RoadActive Suspension systems are designed as bolt-on leaf spring support systems. Review the installation instructions for the specific kit before fitting.
