Product Details
PRIMAAX? EX is a premium, heavy-duty air suspension designed specifically for the rigorous demands of vocational, severe-service and heavy-haul applications. PRIMAAX EX provides the same benefits
as standard PRIMAAX with additional features designed to increase durability, reliability and handling characteristics. The optimized geometry features a new frame hanger and torque rod
configuration that provides increased roll stiffness and reduced roll steer for improved handling. Suspension-induced driveline vibration is significantly reduced with PRIMAAX EX compared to
competitive trailing-arm air suspensions.
- Redesigned cast structural beams utilize premium materials to improve durability more than 350%*
- New, more robust frame hanger design to meet a variety of grueling vocational and severe-duty applications
- Optimized suspension geometry contributes to more than twice the roll stability of competitive air suspensions, helps improve handling and roll stiffness for expanded applications and significantly controls suspension-induced driveline vibration
- Structural beams include integrated end caps that form a solid connection with the square cross brace to form a rigid torsion system for improved stability and control
- Superior off-road mobility with up to 12.5 inches of diagonal wheel travel and 8 inches of vertical axle travel
- Advanced-design air springs lift and support the load with less air pressure, while providing superb ride quality
- Premium, heavy-duty bushings require no lubrication for reduced maintenance
- QUIK-ALIGN? system helps simplify axle alignment for reduced maintenance time and extended tire life
