RoadActive Suspension Ford F-250 F-350
Why Choose RoadActive Suspension for Your Ford F-250 or F-350?
RoadActive Suspension is a mechanical suspension support system designed to reduce rear-end sag, improve towing stability and enhance the handling of Ford F-250 and F-350 trucks.
Whether your truck is towing a caravan, fifth wheel, horse float, machinery trailer or carrying a canopy, truck camper or other constant load, RoadActive Suspension works with the existing rear leaf springs to provide additional support when it is needed.
Unlike airbags, RoadActive Suspension requires no compressors, airlines or ongoing pressure adjustments. The system responds automatically as the suspension moves, helping the truck remain more level, stable and controlled during everyday driving, towing and load carrying.

Important overload spring fitment information
Ford F-250 and F-350 trucks may use different RoadActive Suspension kits depending on whether the rear suspension is fitted with an overload spring. Do not select a kit based only on the truck model or duty name. Inspect the rear leaf spring assembly and review the individual product fitment information before ordering.
Standard Duty, Heavy Duty or Mega Duty?
Standard Duty
Standard Duty is suitable for general towing, touring, everyday driving and vehicles carrying moderate or occasional loads. It provides additional rear suspension support while maintaining controlled and comfortable road manners.
Heavy Duty
Heavy Duty is designed for more demanding towing, larger constant loads, canopies and commercial applications. The correct kit may depend on whether the truck is fitted with a rear overload spring.
Mega Duty
Mega Duty provides the highest level of RoadActive Suspension support for applicable F-250 and F-350 models. It is intended for demanding applications such as truck campers, heavy fifth wheels and substantial constant loads.
How Do I Know if My Truck Has an Overload Spring?
Inspect the rear leaf spring assembly
An overload spring is an additional leaf used to provide extra support as the rear suspension compresses under heavier loads. Depending on the truck and suspension configuration, it may appear as an additional leaf positioned separately from the main spring pack.
Because F-250 and F-350 suspension configurations can vary, check both sides of the rear suspension and compare the vehicle against the product fitment details. When uncertain, send our Australian team clear photos of the rear leaf spring assembly before ordering.
