The SAF-HOLLAND CBXA AeroBeam Series of Fixed Frame Suspensions is a line of lightweight top mount trailer fixed frame air suspensions and includes 23,000-, 25,000-, and 30,000-lb. capacity models. The lightweight cast steel trailing arm beam boasts durability, while providing low overall system weight. The integral shock absorber design improves ride performance, provides undercarriage clearance, and protection from road debris. To further improve suspension life, the pivot connection tension control bolt maintains proper clamp force. The constant clamp force design prevents bushing and frame brackets from wearing out, avoiding premature tire wear. Features the patented SwingAlign system.
