      Description

      Powerful, Quiet Towing. The A25 Sliding 5th Wheel Trailer Hitch delivers heavy‑duty performance—25,000 lb GTW and 6,000-pound vertical capacity—while reducing noise and shock during towing. It’s designed specifically for GMC Sierra 2500HD models with the 6.5‑ft standard box and factory 5th wheel prep, making setup fast and reliable.

      Construction and Appearance. Built with a cast steel yoke and heavy‑duty interlocking jaws, the hitch head features poly‑torsion inserts to buffer road shock and minimize noise. Finished in a durable carbide black powder coat, it resists corrosion while maintaining a rugged, professional appearance.

      Installation. Installation is straightforward using the truck’s OEM puck system and the included S25 slider. No drilling is required—simply drop in quarter‑turn anchors into the bed pucks and lock in place.

      Warranty. Backed by a limited lifetime warranty on structure, with a one‑year coverage on finish and parts.

      Application. This A25 Sliding 5th Wheel Trailer Hitch fits 2016‑2019 GMC Sierra2500HD models with the 6.5‑ft standard box and 5th wheel prep package.
