The **NSA RV Hercules 12K Tow Bar** is the ultimate solution for flat towing heavy-duty vehicles behind your motorhome, RV, or truck. Built with **aircraft-grade aluminum** and reinforced steel components, this tow bar delivers unmatched strength and durability while maintaining a lightweight design for easy handling. Its **12,000 lb towing capacity** makes it ideal for towing large trailers, boats, or even commercial vehicles—providing the confidence you need for safe, reliable towing on any terrain.
A standout feature is the **ReadyBrake supplemental surge braking system**, a fully mechanical design that applies proportional braking force directly to your towed vehicle without relying on electronics or power drains. This ensures consistent stopping power, even in extreme conditions. The tow bar also includes telescoping arms and rotating clevis connectors for effortless hookup on uneven surfaces, while the included **in-dash monitor** provides real-time feedback on brake engagement and system status.
