SAF-HOLLAND CBXA AeroBeam fixed frame trailer suspension expands its lineup with the CBXAS25 and CBXAS30 models, completing a family that now spans 23,000-, 25,000-, and 30,000-lb. capacities for on-highway and on/off-highway trailer applications, including tanker, bulk, refrigerated, platform and specialty fleets. The suspension uses a lightweight cast steel trailing arm beam designed to reduce overall system weight while maintaining durability, with an integrated shock absorber to improve ride performance and protect components from road debris. Features include a pivot connection tension control bolt to maintain clamp force without re-torquing and a SwingAlign axle alignment system that allows adjustments without disassembly. Available with P89 air disc brakes and multiple mounting configurations.
