Hendrickson, a global leader in reliable ride solutions for the commercial transportation industry, is highlighting its proven portfolio of trailer air suspension solutions for trailers, featuring ULTRAA‑K®, VANTRAAX® and INTRAAX®. Building on decades of trailer suspension expertise and a reputation for reliable performance, Hendrickson helps keep fleets moving. These solutions improve ride quality, reduce maintenance and support long-term asset value for fleet maintenance leaders, operations teams and equipment specifiers.
Today, more than 70 percent of fleets in the U.S. market use air suspensions on their trailers (Source: Hendrickson). Fleets originally moved to air suspensions to reduce shock and vibration transmitted from the road, which helps cut wear and tear on trailers, extend trailer life and improve resale value. In addition, air suspensions can enhance tire life, support better fuel economy and provide the smoother ride and cargo protection that drivers and shippers increasingly expect. With decades of experience in trailer air suspension design and integration, Hendrickson is a leading partner for fleets that rely on air systems across their trailer portfolios.
INTRAAX sits at the core of Hendrickson’s trailer suspension lineup as one of the industry’s first fully integrated trailer air suspension systems. It brings the suspension, axle and brakes together in a single engineered system where each element is tuned to work as part of an optimized, harmonious design. It is specifically designed for platforms, tankers, dumps and specialty trailers and is engineered to deliver smooth ride control, confident braking and long‑term durability. It also helps fleets manage weight and maintenance through LDA™ Large‑Diameter Axle and integrated system weight savings.
INTRAAX highlights:
- Integrated suspension, axle and brake system engineered as a single, optimized package to maximize value and performance for modern fleets.
- Advanced axle wrap design and window weld that provide optimal structural integrity
- LDA Large‑Diameter Axle technology to increase stiffness and payload potential while supporting better tire wear and fuel economy versus conventional 5‑inch axles.
- Uptime‑focused design with fewer parts, easy QUIK‑ALIGN axle adjustment and long‑life TRI‑FUNCTIONAL® bushings to help reduce maintenance and keep trailers on the road.
For dry van and refrigerated trailers, VANTRAAX pairs the proven INTRAAX integrated suspension with Hendrickson’s patented K2 slider box to deliver a robust, weight‑efficient air slider system for regional and long‑haul operations. The K2 design and diagonal K‑bracing provide an optimized strength‑to‑weight balance, helping the slider resist racking and harsh loading while supporting higher payloads. Together, its ride and alignment features help trailers track straighter, reduce irregular tire wear and cut rolling resistance that can hurt fuel mileage.
VANTRAAX highlights for dry van and refrigerated trailers:
- K2 slider box and diagonal K‑bracing deliver an optimized strength‑to‑weight design for demanding dry van and refrigerated applications.
- High‑strength main rails and robust slider components help the system resist racking and harsh loading in regional and long‑haul service.
- Driver‑friendly QUIK‑DRAW® pneumatic pin‑pull mechanism reduces driver strain when repositioning the slider
Together, Hendrickson’s integrated INTRAAX and VANTRAAX trailer suspension systems deliver a smooth ride whether trailers are loaded or unloaded, helping reduce driver fatigue, minimize road‑induced cargo damage and cut wear and tear on the trailer chassis.
For fleets pushing payload and efficiency in dry van and refrigerated applications, ULTRAA‑K is Hendrickson’s next‑generation lightweight tandem air slider. A reinforced main rail, overlapping frame brackets, optimized crossmembers and diagonal K‑bracing create a rigid, stable structure that stands up to repeated loading, docking and tight maneuvers. Its weight-optimized design delivers strength comparable to standard and heavy-duty 40,000-pound sliders while reducing weight by up to nearly 100 pounds versus typical tandem air sliders.
ULTRAA‑K highlights:
- Standard with exclusive ZMD® “shockless” ride technology that eliminates conventional shock absorbers from the maintenance schedule.
- Service‑friendly details such as improved air spring access, protected height control valve mounting and pivoting mud flap brackets to help reduce downtime and nuisance repairs.
Across ULTRAA‑K, VANTRAAX and INTRAAX suspension systems, Hendrickson also offers value‑add technologies such as ZMD® ZERO MAINTENANCE DAMPING® air springs, RTR® READY-TO-ROLL® wheel‑end packages and TIREMAAX® tire pressure control systems, giving fleets additional options to enhance performance, reliability and total cost of ownership.
By integrating trailer air suspension, axle and brake technologies into fully engineered systems, Hendrickson delivers reliable, high‑performance trailer suspensions that outperform traditional designs. These optimized, integrated air systems reinforce Hendrickson’s position as a leader in trailer suspension technology and help modern fleets boost uptime, protect asset life and spec advanced suspensions for demanding dry van, refrigerated and platform applications.
