The Wacker Neuson Towbar Complete is a genuine OEM component designed for the APT4T, APT6T, and APT8T series pump trailers, covering both surge brake and electric brake configurations, including cold weather variants. As a direct OEM replacement, part is manufactured to the same standards as the original unit, ensuring correct geometry, hitch interface, and brake system compatibility straight out of the box. This towbar assembly covers the full range of APT pump trailer configurations, making it the right call whether you're running a standard or cold weather spec machine. Keep your trailer road-legal and structurally sound by replacing a worn or damaged towbar with the correct Wacker Neuson part.
Key Features
- Full OEM Structural Integrity — Manufactured to the same load ratings and weld specifications as the original towbar, ensuring the hitch connection is as strong as the day the trailer left the factory.
- Brake System Compatibility — Engineered to work correctly with both surge brake and electric brake setups, preserving the brake actuator alignment and function without adaptation.
- Broad APT Series Coverage — A single part number fits APT4T, APT6T, and APT8T pump trailers, including standard and cold weather variants, simplifying parts procurement across your fleet.
- Maintains Towing Performance — A correctly fitted towbar keeps the trailer tracking true behind the tow vehicle; a bent or cracked bar can cause trailer sway, uneven brake actuation, and hitch wear.
- Brake Safety Compliance — Proper towbar geometry is critical to surge brake performance; using the correct OEM assembly ensures the brake actuator engages at the right deceleration threshold, supporting road safety and DOT compliance.
The towbar is the primary structural link between a trailer and the tow vehicle, transferring towing loads, braking forces, and directional control between the two. On APT series pump trailers, the towbar also houses or interfaces directly with the brake actuator — whether surge or electric — meaning its condition directly affects how and when the trailer brakes engage. A damaged, bent, or corroded towbar can compromise both trailer tracking and brake response, creating a safety risk on public roads and worksites alike.
