RideLite’s® installation process has been described as “seamless” by leading trailer manufacturers. The unit fits virtually all air-ride designed frame configurations without relocation of cross members. Also contributing to a streamlined installation are self-contained shock absorbers, prelocated height control valve mountings and the Huckbolt-secured® solid rubber, double-bonded pivot bushing.

RideLite® meets the needs of today’s weight-conscious fleets. RideLite’s® lightweight design features an economical non-captured axle that allows for axle replacement, if necessary, while the suspension is preserved. The use of Grade 80 high tensile steel combined with a streamlined pivot bolt and alignment system further weight savings and eliminate the need for cross channel or additional wings at the hanger.

Hendrickson AR2 Air Suspension

Maximize Driver Comfort

The Hendrickson AR2 gives you a better ride empty or loaded and improved suspension performance by converting your RT/RTE suspension into a highly engineered and lighter weight walking beam air ride.

Maximize Uptime

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 bushing extends service life and provides alignment capability. Rubber bushings enhance articulation and help reduce load on mating components.

Maximize Traction

AR2 provides the versatility for demanding job sites or off road conditions. When loaded, AR2 delivers up to 14 inches of diagonal wheel articulation to keep load on all drive wheels.

AR2 Conversion

Kit includes two new trailing arm and saddle assemblies, shock absorbers, heavy duty transverse torque rods, height control valves, four air springs, frame hangers, detailed installation instructions and a parts list.

Undrilled frame hangers are provided to accommodate numerous hole patterns
