Master The Road
Roadmaster Active Suspension (RAS) is the only rear leaf spring suspension upgrade that converts basic “passive” leaf spring suspension to mechanical “active” suspension. Our system strengthens the rear leaf springs by absorbing and dissipating load force energy, resulting in significantly improved load and road handling without ever compromising ride quality. Add strength and stability without readjustments or maintenance. Master The Road.Product Video
