Every serious hauler knows the neck is the lifeline of a trailer. It's the part that takes the most strain, especially when you’re fully loaded and maneuvering through tight job sites or winding backroads. That’s why we created the Neck Boss design, a structural reinforcement that brings long-lasting strength right where it's needed most.

Why the Neck Matters

The junction where a trailer's neck meets the main frame is a constant target for stress. Under heavy use, this area can become a weak point that leads to bending, weld fatigue, or outright failure. For many users, especially those hauling daily, this results in costly downtime and repair bills.

Our Neck Boss solution is a proactive reinforcement, it ensures that your trailer won’t just survive tough jobs, but thrive under pressure.

Inside the Neck Boss Structure

We didn’t just slap some extra metal on and call it good. The Neck Boss design includes custom gussets and angle plates create a rigid, interlocked structure, while weld-through reinforcements connect deeper into the frame to strengthen overall integrity. Additionally, the optimized geometry distributes pressure evenly across multiple planes, enhancing durability and reducing stress concentration points. This design minimizes flex and keeps structural stress away from critical weld points.

Smart Engineering for All Trailers

We’ve built the Neck Boss into both our gooseneck and bumper pull lines, with adjustments tailored to each platform:

On goosenecks, it fortifies the long neck against vertical stress and side loading common in industrial hauls. On bumper pulls, it strengthens the tongue area without adding bulk or weight, a win for both safety and fuel efficiency

Whether you're towing 5,000 lbs or 15,000 lbs, the result is the same: more confidence at the core of your trailer.
