XB Tag Suspension

A tag axle allows for increased GVWR, enhanced maneuverability and superior handling.

 

 

ZF Tag Suspension

10,000 – 20,000 lbs.

Thanks to its modular design, the ZF axle systems allows for tailored axle configurations, depending on the installation environment. The independent suspension allows for active or passive steering; steered axle systems increase a coach’s maneuverability, enabling much smaller turning circles and reducing tire wear, while ZF’s passive tag axle features steering dampers and pneumatically activated lock cylinders. For active rear axle steering, ZF’s RAS/RAS-EC systems are the perfect solutions.

Neway Tag Axle

More than just an “add-on” to handle more weight, the Neway Tag Axle is designed to be integrated into the overall chassis and braking system, enhancing overall stability and providing consistent braking.

  • Additional payload capacity – up to 47,000 lb. GVWR
  • Longer floor plans – the tag axle accommodates floor plans up to 45 feet for more space and design options
  • Automatic load proportioning system – an industry first – distributes weight proportionately across all three axles to ensure a smoother, more comfortable ride and decrease tire scrub during low speed and back up
  • CAD-designed coupling plate provides superior strength in high-stress areas
  • Five-year, 100,000-mile coolant is pre-charged with SCA
  • Air-disc brakes with ABS dramatically decrease stopping distance in virtually all braking conditions, while minimizing fade during rapid or extensive application of the brakes

UltraSteer®

Handling Luxury with Precision.

As the first line of tag axles that are fully-integrated and precision-tuned to react to turns and maneuvers of the coach, UltraSteer establishes a new standard for premium ride and handling.

Features

  • Auto-Locks to straight @ 20mph and in reverse for complete control
  • Flexible coach packaging for increased storage options
  • QuickAlign and optimized rubber bushings increase suspension life and reduce maintenance
  • Compatible with disc and drum brakes

Increased Maneuverability

  • Significant reduction in curb-to-curb turning radius
  • Remarkably tight turning angle

Improved Ride & Handling

  • UltraSteer’s outboard-mounted design is more reactive to roll input than inboard-mounted shocks, which improves handling in turns and maneuvers such as sudden lane changes
  • Wide track suspension arms provide increased lateral stiffness over narrow track suspension arms, improving handling and safety (B-Series)

Tire Savings

  • In contrast to rear mounted tie rods that can still cause tire scrub, the UltraSteer’s forward-mounted tie rods and correct steering geometry enable the inside wheel to have a 12° turning angle and follow the ideal turning path—eliminating tire scrub

Options

  • B-Series

    A straight beam axle and wide track suspension arms provide increased lateral stiffness, delivering improved handling and safety in turns and sudden maneuvers while offering OEMs flexible floorplan options.

  • I-Series

    An independent suspension on the tag axle provides enhanced overall ride quality and stability, with a comparable weight capacity and turning angle to the B-Series.
