Maintain peak suspension performance with Hendrickson Genuine Parts

Over the decades, Hendrickson Trailer Commercial Vehicle Systems has manufactured millions of air suspensions and integrated systems for trailers. Air springs, shocks, bushings, axles, brake systems and air controls are designed, tuned and tested to ensure they function harmoniously to provide superior suspension system performance. Using Hendrickson Genuine Parts helps ensure the continued reliability and performance you expect from Hendrickson.

Air Springs Not all air springs are created equal. Differences in air spring piston design, flex member length and overall dimensions may not be obvious. Critical dimensions not visible to the naked eye, including variations in internal bumpers and flex member bias angles, can alter air spring performance. Additionally, mixing air spring designs may cause adverse loading conditions within the suspension system. Always choose Hendrickson Genuine air springs for correct fit, exceptional ride quality and long service life.

Shocks Hendrickson shocks are designed with specific strokes, seal designs, bore diameters and damping characteristics to optimize the overall performance of the suspension system. Collapsed and extended lengths are critical to air

spring, mounting clevis and trailer cross member integrity and life. For example, using a shock with a longer stroke than required may result in overextension of the air spring; too short of a stroke can damage mounting clevises or trailer cross members. To ensure optimal suspension performance, always ask for Hendrickson Genuine shocks.

Bushings Hendrickson pioneered the use of a single, large-diameter bushing in trailer air suspensions with our TRI-FUNCTIONAL ® bushing. Coupled with our rigid beam and solid axle connection, Hendrickson’s TRI-FUNCTIONAL bushings deliver enhanced ride and road stability, for a dependable system that provides extended life, reduced maintenance and cargo protection. The void design and material composition of these unique bushings are critical to controlling the horizontal, vertical and roll forces a trailer generates rolling down the road. Insist on Hendrickson Genuine TRI-FUNCTIONAL bushings for exact fit and optimum performance.

ZMD ® Frequently Asked Questions

GENUINE PARTS

1. What is ZMD ® ZERO MAINTENANCE DAMPING ® technology? ZMD ZERO MAINTENANCE DAMPING technology consists of a patented ▲ air spring and a down stop that are designed to replace the function of a standard shock absorber to help lower maintenance, improve ride quality and enhance cargo protection. 2. What are the benefits of ZERO MAINTENANCE DAMPING technology? ZMD offers improved ride quality and helps lower maintenance over the trailer’s life cycle due to the elimination of the shock absorbers. It provides better cargo protection and reduces the risks associated with possible CSA violations of applicable U.S. Federal Motor Carrier Safety Administration regulations.

3. What are the advantages of ZMD air springs compared to shocks over the lifetime of the trailer? Shocks are a common maintenance item on air suspensions that must be replaced periodically. Over time, as shocks wear, their damping capabilities also diminish. ZMD air springs are designed to provide continuous and consistent damping levels throughout the life of the air springs. Since there are no shocks to wear out, the ZMD option helps save time and labor costs over a trailer’s life cycle. 4. What are the key design features of ZMD air springs? The main components of a ZMD air spring are similar to those of a standard air spring - both have a rubber bellow and a steel or plastic piston. The internal design components of this patented air spring are specifically designed to perform the suspension damping function traditionally performed by the shock. 5. How does a ZMD air spring work? The ZMD air spring exchanges pressurized air between the bellows and piston through channels that interconnect to provide continuous suspension damping. 6. Traditionally, shock absorbers are responsible for controlling the travel of a suspension to prevent overextending the air springs. Since ZMD eliminates the shocks, how will the travel be controlled? The ZERO MAINTENANCE DAMPING design features down stops to limit suspension travel. The down stops are installed where the shocks would traditionally be. 7. Is ZMD available on all suspension systems? NO. Currently ZMD is standard on ULTRAA-K ® air slider systems. It is an option on select VANTRAAX ® and INTRAAX ® models. Only VANTRAAX HKANT 40K with a 16-inch ride height equipped with Hendrickson’s QUIK-DRAW ® fully pneumatic pin-pull system are available with ZMD. INTRAAX AANT 23K and AAT 23K / 25K models with a 14-inch through 17-inch ride height and standard travel are available with ZMD. INTRAAX AAT 23K / 25K RCA models with a 14-inch or 16-inch ride height and limited rebound travel are available with ZMD. 8. Is ZMD the only option available when specifying a new VANTRAAX or INTRAAX suspension? On select VANTRAAX HKANT 40K models and select INTRAAX AANT 23K and AAT 23K / 25K models, ZMD is an option that is available to customers who wish to upgrade their suspension. Customers still have the option of specifying a suspension with standard air springs and shocks on the HKANT 40K, AANT 23K and AAT 23K / 25Kmodels. (Please refer to Hendrickson Literature Numbers L602 INTRAAX Ordering Guide, L544 VANTRAAX Ordering Guide and L1226 ULTRAA-K Ordering Guide for a complete list of options) 9. Can ZMD be retrofitted on existing trailers in service? YES. ZMD air springs and down stops can be retrofitted on select VANTRAAX and INTRAAX models with the following specifications. VANTRAAX HKANT 40K models require a 16-inch ride height and QUIK-DRAW ® . ZMD is compatible with Hendrickson’s SURELOK ® device. INTRAAX AANT 23K and AAT 23K / 25K models are available with 14-inch through 17-inch ride heights and standard travel. INTRAAX AAT 23K / 25K RCA models are available with 14- or 16-inch ride heights and limited rebound travel. Please call Hendrickson for assistance in ordering a ZMD retrofit kit.

Contact your Hendrickson Customer Service Representative for more details. 13. Why is ZMD limited to specific ride heights on ULTRAA-K, HKANT 40K and select top-mount INTRAAX models? ZMD is currently limited because this patented air spring is rated for 20K axle applications. Additionally, the down stop has been rigorously tested for these specific applications. 14. How are ZMD air springs installed? ZMD air spring installation procedures and mounting hardware are identical to standard air spring and shock installation procedures. To install ZMD air springs as a retrofit, simply remove the existing shocks and air springs and replace with ZMD air springs and down stops. The select INTRAAX AANT 23K models that are available with ZMD require an additional bolt to be added to the shock clevis on winged hangers only. Follow all applicable Hendrickson installation, service, maintenance and repair procedure publications. 15. Can standard air springs be mixed with ZMD air springs? NO. Mixing ZMD air springs with standard air springs is not recommended.While the load curves for each product are somewhat similar, they provide different damping performance to the suspension system. Mixing ZMD and standard air springs on the same suspension can adversely affect the operation and life of other integral suspension components. 16. Can ZMD air springs equipped on VANTRAAX ® and INTRAAX suspensions be interchanged? NO. Both ZMD and standard air springs are specially designed to meet the needs and geometry of the specific application. It is important to use only the exact air springs specified by Hendrickson for each model to ensure maximum operation performance and life of components. 17. How can customers tell the difference between a ZMD air spring and a standard air spring? The customer must visually inspect the air spring to verify the type of air spring. Identifiers include: • ZMD embossed on the bellows • Part number • Down stop instead of shocks Similar to today’s standard air springs, the Hendrickson part number will be located on the ZMD air spring bellows. 18. Is there slack in the down stop on ZMD? • Sealed piston bottom • Black plastic on ULTRAA-K

YES. There is slack in the down stop to allow 3 to 4 inches of suspension travel on ULTRAA-K ® and VANTRAAX HKANT 40K models. The select top-mount INTRAAX models available with ZMD will allow for 2 inches of suspension travel. 19. Will the down stop kink or twist? The down stop cover helps prevent the down stop from twisting and kinking at installation and while the trailer is in service.

GENUINE PARTS

Hendrickson genuine replacement cam tubes Hendrickson’s revolutionary Cam Tube System ™ is patented ▲ with a unique 4-tabbed design. Engineered to perform, this 4-tabbed Cam Tube System is manufactured with tight tolerances creating a clamping force that is symmetric around the cam tube.

▲ This product is covered by at least one or more U.S. and/or foreign patents and/or pending U.S. and/or foreign patent applications. See Hendrickson for details.

Hendrickson’s 4-Tabbed Design

Competitor’s 2-Tabbed Design

Competitor’s O-Ring Design

Structural Design Hendrickson’s 4-tabbed design is manufactured to perform. • The symmetric clamping holds the cam tube in position to help prevent cam tube rotation, which can cause premature wear to the brake spiders and could result in an expensive replacement of the HALFTRAAX ™ axle / beam weldment. Bent washer design provides increased durability and resistance to rotation versus the flat design. • Bent to allow the washer to be common between a 15" and 16.5" diameter INTRAAX ® brake.

Mechanical Properties Hendrickson’s cam tube clamping bracket is manufactured using high- strength, low alloy, high quality steel. • On certain will-fit brands of cam tubes, testing indicates the clamping bracket mechanical properties have a lower torque causing less resistance to movement than Hendrickson’s bracket. • The clamping force will not deform the plate. Hendrickson’s cam tube bushing has internal lubricants to reduce friction and extend wear life.
