Frequently Asked Questions

No aftermarket suspension product can legally increase the manufacturer’s rated payload capacity.

However, RoadActive Suspension helps your truck handle payload more effectively, reducing squat, improving stability, and maintaining better ride control when carrying equipment.

RoadActive Suspension does not create a permanent lift.

Instead, it helps maintain the proper arch of the leaf spring under load, which helps reduce sag when the truck is carrying tools or equipment.

Yes. RoadActive Suspension is ideal for trucks that carry consistent daily weight such as tools, equipment, ladder racks, or service bodies.

The system reinforces your factory leaf springs, helping maintain proper suspension geometry under constant load. This reduces sag, improves stability, and helps the truck handle better throughout the workday.

No. RoadActive Suspension uses a progressive mechanical spring that increases support only as load or force increases.

When the truck is lightly loaded or empty, the system remains mostly neutral, helping preserve factory ride quality while improving overall stability.

Yes. RoadActive Suspension has been used on work trucks and fleet vehicles for over 25 years.

Because the system is fully mechanical—with no airbags, compressors, or electronics—it is extremely durable and requires virtually no maintenance, making it ideal for demanding work environments.

No. RoadActive Suspension is a bolt-on suspension enhancement that does not modify the factory suspension components.

Under the Magnuson-Moss Warranty Act, installing an aftermarket product cannot automatically void your vehicle warranty unless it is proven to cause a specific failure.
