Fontaine Fifth Wheel operates as a leading manufacturer of fifth wheel couplings for heavy-duty trucking and is widely recognized as the largest dedicated producer in this niche. The company has introduced No-Slack automatic slack adjustment, a feature intended to maintain a secure connection as wear develops. It runs ISO/TS 16949:2009 certified manufacturing facilities across three regional groups—North America, South America, and Europe—with its North American base in Jasper, Alabama, housing both its corporate headquarters and a major research and development center focused on fifth wheel technology. The company's offerings cover stationary, sliding, and blocked fifth wheels that feature automatic slack adjustment to minimize wear on the coupling. The technology is intended to extend component life and reduce maintenance, translating into lower operating costs per mile and a smoother ride for drivers; in 2026 Fontaine announced a partnership with Aperia Technologies to integrate fifth wheel data into Halo Connect fleet management.
