Atro’s Freightliner TufTrac Suspension is designed for vocational uses such as refuse, construction, asphalt spreading, heavy hauling, mining, logging, oil/gas field service and high-center-of-gravity applications. Available in 40k, 46k and 52k capacities, TufTrac combines parabolic springs with elastomeric load cushions. The center elastomer load cushion acts as a pivot point to allow articulation while smoothing out the typically harsher ride experienced with spring-only suspensions. The end spring pads help cushion the ride, especially when unladen, while reducing noise and vibration. The suspension’s design also raises the undercarriage components for more ground clearance. Atro offers two options for the 40k and 46k models: TufTrac and 2-Stage Tuftrac, which uses a load cushion with a softer spring rate due to voids in the rubber material between the steel plates.
