Description The 7K RAM Collar Style A-Frame Coupler, part #31-CA-519-B, gives you a tough, reliable trailer hitch connection. It fits trailers with an A-frame tongue. It uses a 2″ hitch ball and handles up to 7,000 lbs of gross trailer weight capacity. This coupler works great on utility trailers, cargo trailers, ATV trailers, and equipment trailers that use a 50-degree A-frame mount. You install this coupler by welding it directly onto the A-frame trailer tongue. The collar style latch locks snugly around the ball, so it keeps the connection tight in both static and dynamic towing conditions. The hinged ball socket makes hookup easy and smooth. You get a clear visual cue when the latch fully closes. The design fits common trailer applications for everyday towing. You use this coupler with pickup trucks, SUVs, and light-duty tow vehicles that sport a 2″ trailer hitch ball. The cast steel and collar-lock style give you strength and durability you can trust on long hauls or rugged jobsites. Customers who build, repair, or upgrade trailers love how simple this part installs. They like the tight ball fit and low-profile latch design. The welded A-frame mount prevents movement and play behind the tow vehicle. You can match this coupler with safety chains, jack mounts, and trailer wiring kits for a complete towing system.
