- Large volume air springs support the entire load to improve spring rate by up to 34%*
- Patented, maintenance -free torque box system improves multi-axial stability and control.
- Highly efficient and lightweight design.
Non-torque Reactive System
- Unique parallelogram geometry eliminates frame rise and helps reduce suspension induced driveline vibration.
- Pinion angle remains constant even with changes in ride height.
