INTRAAX® AANL 23K trims 75-pounds from the proven low-ride suspension system leader

Hendrickson squeezes 75 pounds from the popular INTRAAX® low-ride / liftable integrated trailer suspension system with the launch of the INTRAAX AANL 23K scheduled in the second quarter of this year.


INTRAAX AANL 23K replaces the successful AAL 23K as Hendrickson™s lightest 23,000-pound capacity low-ride / liftable suspension system, giving fleets and owner operators a savings of approximately 150 pounds on tandem axle trailers.



Scheduled for introduction at the Mid-America Trucking Show, AANL 23K provides all of the benefits of INTRAAX including the first standard trailer Cam Tube System to reduce S-cam maintenance and the industry™s straightest world-class axle to help stretch fuel mileage and extend tire life. Standard QUIK-ALIGN® delivers fast, easy, accurate axle alignment.


Offered in ride heights from 6.5 to 17 inches, AANL 23K brings road-proven, tapered-beam and large-diameter axle (LDA) technologies to drop-decks, lowboys, platforms, tankers, bottom dumps and specialty trailers.


The INTRAAX AANL system uses Hendrickson™s Advanced Axle / Beam Technology (AXT), which teams tapered-beam and LDA technologies, to enhance component system strength, while reducing weight compared to similar-capacity suspension systems.


While the lighter weight of the tapered-beam construction allows haulers to carry more cargo on each run, the AANL 23K delivers the exceptional freight protection, superior performance and rugged durability that have made INTRAAX the leader in quality and technology in the air-ride suspension market.




The AANL tapered-beam design uses the high-performance TRI-FUNCTIONAL® III Bushing to deliver an outstanding ride. Road proven over millions of miles on systems including INTRAAX AANT, patented TRI-FUNCTIONAL III Bushings feature phosphate coated inner metal for corrosion protection and a unique rubber compound for outstanding durability and ride.


LDA increases the diameter of today™s traditional five-inch axle by about three-quarters of an inch while slightly reducing the wall thickness, which reduces weight while improving component and system strength.


LDA delivers as much as a 22-percent increase in bending and torsional stiffness compared to the five-inch axle tube. This reduces tube deflection under loads to keep the axle straighter and help enhance fuel efficiency and tire wear.
