SAF-Holland Cuts 30+ Pounds From Slider With Tougher UltraLite40 Design

Key Details SAF-Holland has redesigned the UltraLite40 Slider for its ULX40 Mechanical Sliding Suspension and Axle System, delivering a lighter, more durable option for on-highway van and refrigerated trailers. The new 40,000-pound system sheds more than 30 pounds while offering three times greater durability compared to the previous generation. Why It Matters Weight reduction directly increases payload capacity and fuel efficiency, addressing two critical pain points for trucking operations. The redesign extends trailer lifespan and simplifies OEM installation, helping manufacturers reduce parts inventory and production costs. What's New The ULX40 comes fully assembled with suspension, axle, brakes, and controls from one source, backed by a 10-year warranty. SAF-Holland engineered the system using years of real-world operating data and tested it under more demanding cycles. Robotic welding and streamlined manufacturing improve consistency and supply reliability, with standard galvanization protecting against corrosion. Timeline The UltraLite40 Slider will be available in the fourth quarter. Simplified configurations mean fleets can integrate the system across multiple applications without complex customization.
