Henderickson Auxiliary Axle Systems’ upgraded 20,000-pound capacity Paralift steerable truck lift axle system features adjustable ride height and frame width capabilities. The trailing arm beams evolved from a dual paddle, triangular cross section design to a more efficient single paddle, z-beam configuration. The zero torsion, trailing arm bushings help eliminate bushing wind-up and allow for the single air spring configuration. The lift springs design and a repositioned stabilizer increases the wheel cut from 18 degrees to more than 25 degrees for improved maneuverability and tire wear.
