SECTION 2

Product Description
The Hendrickson AR2 offers a better ride and improved suspension performance by converting
your Hendrickson RT™•RTE™ suspension into a highly engineered and lighter weight 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.
AR2 provides versatility for demanding job-sites or off-road conditions. When loaded, AR2 delivers
up to 14" (356 mm) of diagonal wheel articulation to keep load on all drive wheels.
Unloaded articulation varies with vehicle configuration and empty body weight. Available in conversion or complete kit form with 40,000 and 46,000 pound (18,144 and 20,865 kilograms)
capacities, AR2 can be installed by service centers and OEM dealerships who want to give their
customers a new suspension solution.
