Hendrickson Auxiliary Axle Systems has introduced an upgrade to its 20,000-lb. capacity Paralift steerable truck lift-axle system, providing adjustable ride-height and frame-width capabilities. By combining unique frame-width and ride-height spacers with a slotted crossmember, the company has designed a system that enables aftermarket installers and body builders to stock one unit to meet a wide variety of truck configurations. According to Hendrickson, the trailing arm beams now form a more efficient single paddle, z-beam configuration. In addition, zero-torsion, trailing-arm bushings help eliminate bushing wind-up and allow for the single air spring configuration.
When used with the new lift springs design, a repositioned stabilizer increases wheel cut from 18 deg. to more than 25 deg. to help improve maneuverability and tire wear.
With a 1,465-lb. system weight, the Paralift offers a 160-lb. weight savings compared to the previous model. It features 12 in. of total travel, with 9 in. of lift in ride heights from 9 to 13.5 in., all in a 28-in. package space.
