This coupler combines with a Lock 'N' Roll vehicle-end hitch (sold separately) to create a safe, secure, fully articulating connection that's great for towing whether you're on the road or off-road. It's more secure than a traditional ball coupler, and it's more comfortable and quieter than a pintle setup. The Lock 'N' Roll connects quickly and easily, and can adapt to any towing conditions.

Strong, Safe Connection

When using a traditional ball coupler, it can be hard to tell if the coupler is fully latched around the ball. You can head out assuming the connection is secure, only to have the trailer pop off of the ball and disconnect while you're towing. With the Lock 'N' Roll, that won't happen.

Lock N Roll Connected

This unique coupler is designed to interlock with a matching vehicle-side hitch to form a tight, secure connection. Unlike on a ball coupler, the latching components on the Lock 'N' Roll system are easy to see, so you can tell at a glance if the connection is secure.

Once secure, the Lock 'N' Roll setup offers a wide range of motion, which makes for a smooth ride. Because of the articulating action of the combined coupler and hitch, the Lock 'N' Roll connection can handle the harsh bumps and road shock that could otherwise stress and potentially damage a ball coupler.

The Lock 'N' Roll connection also makes your trailer less vulnerable to theft. Unlike a traditional ball coupler, which is compatible with any hitch ball of a matching size, the trailer-side Lock 'N' Roll coupler can only connect to a vehicle-side Lock 'N' Roll hitch. So your trailer cannot be towed away unless it's connected to a vehicle with a Lock 'N' Roll hitch installed.

With the Lock 'N' Roll, you can have peace of mind knowing your connection will not come apart or succumb to damage caused by road shock, nor will your trailer be vulnerable to theft.

Comfortable Off-Road Towing

The pintle hitch connection is the most common setup when towing off road because of the flexibility in the connection. But that flexible connection can also result in a lot of slop. This can cause uncomfortable jerking as well as rattle and noise. In addition, when using a pintle/lunette ring setup, it can be difficult to back up your vehicle and trailer without jackknifing. And it can be hard to disconnect at certain angles, which may be a necessity when overlanding.

The Lock 'N' Roll assembly, on the other hand, offers a close-fit, slop-free connection that's designed for off-roading. This close-fitting design provides a smoother ride than a pintle/lunette ring connection with less rattle. It also makes it easy to back your vehicle and trailer up without jackknifing.

Offroading Jeep with a Lock 'N' Roll hitch

With the trailer end and vehicle end combined, the Lock 'N' Roll setup also creates a fully articulating connection that's great for off-roading. The bearing that's built into the vehicle-end hitch allows for 360 degrees of rotation, which means that your trailer could actually roll all the way over and not take your vehicle with it. The connection also pivots side to side and up and down, making it easy to take rough trails without jarring your setup. This also allows for fast and easy disconnection, even at extreme angles.

How Lock 'N' Roll Works

Lock N Roll Fully Connected

Each Lock 'N' Roll setup requires 2 parts - a trailer end and a vehicle end. Together they create a strong, secure connection. To connect, just line up the trailer end and vehicle end together and place the outer metal tabs of the trailer-end coupler into the hooks on the vehicle-end hitch. Then fold the latching plates on the vehicle-end hitch down and secure them in place over the tabs using the pin and clip included with your vehicle-side hitch. With the latching plates secured, the Lock 'N' Roll assembly will stay firmly connected.

In Action Diagram

When the trailer-side coupler and vehicle-side hitch are secured together, they form an articulating assembly with 3 axes of directional motion. The uniquely designed bearing on the vehicle-side hitch allows the connection to rotate a full 360 degrees. The trailer-side coupler's hinge allows the connection to pivot to the left and to the right. And when the 2 sides are joined, the tabs will roll inside of the hooks so that the entire assembly can tilt up and down.

Towing with the Lock 'N' Roll is easy, and it gives you a connection that's both flexible and secure.

Get Maximum Security Locking Pins

Get extra security for your trailer. InfiniteRule makes hitch pin locks (IR59FR - sold separately) specifically for this Lock 'N' Roll articulating hitch. You'll get two stainless steel locks: one with a 1/2" diameter pin, and one with a 5/8" diameter pin. These will replace the standard pins and clips on the driver-side and trailer-side of your coupler.

Just completed the installation in less than an hour of the Lock N Roll Hitch system, took the trailer for a spin and we’re jazzed about it. This is a well-built, heavy-duty slop. We plan to do some primitive/glamming camping and this trailer is for hauling all our tent stuff. The new “Lock N Load” hitch back up easily, turn corners easily…no jerkiness. Best purchase my wife ever made for us..Oh, besides the off-road enclosed trailer.


I recently purchased a product from etrailer. I’m not much for internet purchases and contacted them to speak directly to a live person. Best call I’ve made in awhile. I spoke with Donna from etrailer and was treated to good ole fashion customer service. Donna was great and a sale and future costumer was made. Great service great product.



Great I am very satisfied with the product


I’ve put this trailer hitch to the test on and off road, it’s a solid performer and is a great addition for anyone wanting to eliminate slop while allowing maximum maneuvering. Highly recommend this hitch system for those who pull any trailer, bonus is it’s unique hitch system and likely hood of theft occurring.


Extremely happy with this purchase and with etrailer.
Ordering was simple, communication from etrailer is excellent, every step of the way. Our first choice for purchases for anything for our offroad trailer and towing will always be with etrailer.

Our hitch we had was a cast iron and supposed to be built for off road camping, when on a steep incline, off camber and making a sudden stop the hitch popped off the ball. What a mess. This hitch will resolve that problem and work as an anti theft hitch since it is unlikely others will have the same hitch set up.


Awesome product. Can’t wait to hit the trail with it


Smooth, No play, and peace of mind that your trailer will stay connected


Been a year using it and have had zero issues. Only downside is that it’s harder to line up than a traditional ball. The tolerances are very tight so when hooking up there is less wiggle room. That’s also a plus for me I’d rather have a good tight fit anyway.


I have order a number items, everything have arrived as described. Very good place to order from. I even had to get a order returned with no issues.
