optimum suspension ride, handling and performance.

■ Performance Ride quality and performance are key factors when designing the internal makeup of Hendrickson air springs. A low natural frequency is achieved through proprietary piston, flex member, and bump stop components. ■ Use Only Genuine Hendrickson Using non-genuine air springs can alter the weight rating and performance of Hendrickson suspensions. Look for the Hendrickson name and logo on the air spring to help guarantee you are getting genuine Hendrickson service parts.

Bolster Springs

GENUINE PARTS

Hendrickson Bolster Springs unique design and high grade rubber boost performance by withstanding heavy loads in rugged applications. In the event that replacement springs are required, Hendrickson supplies the same genuine components for service as installed on the original suspensions. These components have the same design, construction and performance, which helps ensure high end user satisfaction and peak system performance. Correct setup and regular inspections are key in maintaining optimum bolster spring and suspension operation.

HAULMAAX ® Bolster Springs ■ HAULMAAX bolster springs work in conjunction with the load springs and shim plates to provide outstanding ride quality in both loaded and unloaded conditions ■ Load spring shims can be adjusted for different empty body weights, making HAULMAAX suspensions another ideal choice for trucks being used in varying applications TIE-BAR DESIGN

■ While mandatory for 46,000 pound capacity suspensions, an optional tie-bar version is also available for 40,000 pound capacity suspensions ■ Provides greater bolster column stiffness ■ Improves suspension performance even when axles are misaligned ■ Remains consistent with the ride quality and stability of the original design

HN ® Bolster Springs ■ Proprietary rubber compounds are used to provide ideal articulation and ride quality ■ As payload increases, the bolster springs continue to compress until the load springs engage.This produces a secondary system stiffness that provides extra ride stability under loaded conditions ■ HN bolster springs absorb vertical road inputs as well as fore / aft shock to deliver superior driver comfort and handling

Bolster Springs

GENUINE PARTS

Shear and Compression Bolster Spring Loads The shear load component enables high suspension articulation and a lower unladen suspension spring rate. The compression load component allows the suspension to carry heavy loads.Trust genuine Hendrickson bolster springs to deliver these benefits and enable HN and HAULMAAX suspensions to operate and perform as designed. For optimum performance, HN and HAULMAAX suspensions require a soft spring rate when unloaded and a stiff spring rate when loaded.Typical competitor urethane bolster springs do not meet Hendrickson’s spring rate criteria, and their use will void any applicable Hendrickson warranty. In addition, competitor urethane bolsters can degrade ride quality and create excessive stress on the suspension. Hendrickson does not authorize the use of competitor urethane components in any HN or HAULMAAX suspension system.

Center Bushings

GENUINE PARTS

Hendrickson Equalizing Beam Center Bushings

Each Hendrickson center bushing is engineered for specific types of Hendrickson walking beam suspension capacities, applications, and configurations to maximize system performance.To help ensure high end user satisfaction and peak system performance Hendrickson supplies the same genuine components for service requirements as were installed in the original suspensions. Rubber Center Bushings — Proprietary rubber compound provides maximum bushing life while maintaining system performance attributes.

Fully Bonded Center Bushings ■ Designed for high‑capacity Hendrickson walking beam suspensions rated at 52,000 pound capacity ■ Low maintenance, helps maintain low tire wear ■ Provides the extra strength and durability necessary to routinely handle heavy loads ■ The bonded rubber to metal resists friction, therefore improving bushing life

High Confinement Center Bushings ■ Standard on all Hendrickson walking beam suspensions rated up to a 40,000 pound capacity ■ Can be specified up to a 46,000 pound capacity rating, when used in conjunction with transverse rods ■ Maintains a high resistance to bushing walkout over a longer period of time due to the confinement of the rubber

NOTE: These rubber bushings are also available with a loose plug for ease of cross tube installation

Bronze Center Bushings

■ Designed for severe applications that encounter extremely tight turns under heavy loads that are not equipped with transverse torque rods ■ Standard on Hendrickson walking beam suspensions rated at 46,000 and 52,000 pound capacities ■ Bronze bushing grease channels are precisely cut and located to ensure proper grease flow and long bushing life
