AR2 Air Over Walking Beam Suspension

Features and Benefits

  • The Hendrickson AR2 gives you a better ride and improved suspension performance by converting your RT/RTE suspension into a walking beam air suspension
  • The air spring system in AR2 absorbs the load and road inputs — delivering the preferred combination of empty-ride and loaded stability for vocational applications
  • Hendrickson-designed air springs constantly adjust to changing road and load conditions to deliver superior ride quality
  • Improved ride reduces road shock and vibration to the vehicle for longer service life and fewer repairs to the cab, chassis and body equipment
  • Air springs provide long service life and easy replacement
  • Bar pin rubber end bushings extend service life and provide alignment capability
  • Hendrickson parts and service available at thousands of locations worldwide.
  • Comprehensive technical support

Contact Hendrickson for approval of additional applications.

1. Conversion kit center bushing — if existing RT/RTE suspension includes bronze center bushings, they must be replaced with rubber center bushings. Bronze center bushings are incompatible with transverse torque rods.

2. Installed weight is for 52-inch axle spacing. Conversion kit installed weight includes torque rods, axle brackets and frame brackets. Complete assembly installed weight includes fabricated equalizing beam assembly, cross tube, torque rods, axle brackets and frame brackets. Any comparison to other suspensions should consider all of these components, including axle brackets.

3. Contact Hendrickson for applications that may exceed GVW approval ratings.

4. Site Travel Rating — Ratings are limited to no more than 5% of vehicle operation at speed not to exceed 5 mph. Site travel ratings are consistent with published axle manufacturer’s limitations. Axle and suspension site travel specifications must not be exceeded.

5. Suspension articulation may exceed vehicle’s capability and may be limited by vehicle manufacturer; vehicle manufacturer installed axle stops may restrict suspension’s articulation.

6. AR2 is approved for vehicles equipped with aluminum beams up to a 38K maximum capacity.

7. No add-on lift axles
