The trailer coupler is the single most critical connection on your towing setup — it physically links the trailer to the tow vehicle. This 2" coupler features a positive latch mechanism that locks onto the hitch ball with a safety pin to prevent the latch from bouncing open. couplers are built from heavy-gauge steel that resists the corrosion from road salt and weather. Replace when the ball socket shows visible wear, the latch is loose, or the body shows cracks. Rated for 5,000 lbs. ⚙️ Key Features ✅ 2" ball coupler ✅ Positive latch with safety pin ✅ Heavy-duty construction 📐 Specifications Size: 2" Capacity: 5,000 lbs Ball Size: 2" Material: Zinc-Plated 🔄 Cross Reference CT-5003 🔧 Applications Trailer tongue coupler that connects to the 2" hitch ball on the tow vehicle. The coupler is the primary connection point between your trailer and truck — it must be in good condition, properly latched, and correctly sized to the hitch ball. Always engage the latch, insert the safety pin, and verify the coupler is fully seated on the ball before every trip. Replace when the latch mechanism is loose, the ball socket is wallowed out, or the coupler body shows cracks. Match the coupler ball size to your hitch ball — using a 2" coupler on a 2-5/16" ball (or vice versa) is extremely dangerous. 📞 Call/Text: 517-225-1991 🌐 AAATrailer.com
