This hitch combines with a Lock 'N' Roll trailer-end coupler (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 hitch, 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 hitch is designed to interlock with a matching trailer-side coupler 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 hitch and coupler, 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

When combined, the Lock 'N' Roll hitch and coupler also create 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 included pin and clip. 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 parts 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.

Ideal for the rough rigors of off-road towing or overlanding, this vehicle-side hitch works with your trailer-side Lock N Roll coupler (sold separately) to form an extra-strong connection that is safe and secure, no matter the terrain.


Towed my Opus Op4 camper through some of the most gnarly terrain to date. Worked perfectly and I prefer the 4.5" drop/rise compared to the original hitch.


I switched to the Lock N Roll hitch on my raft trailer (will never go back to the ball hitch) and started with the adjustable 4" offset. Having used that for more than a year, I decided to get this fixed 4" offset which will protrude less from the 4Runner's bumper and will be lighter.


The Lock N Roll is a great towing set-up for off road trailers. Super strong, great articulation and made in USA. Just an FYI that I have not seen mentioned on any web site: the rise/drop is measured from the center of the 2" receiver.



It still works great. Really put it to the test crossing the Great Basin west to east and back. My trailer felt safe and secure thru multitudes of different terrain.


This is amazing engineering. It will surely meet and exceed any performance demand I might place upon it.


This is what I have been wanting for a while to off-road my trailer


Well built. A great solution for any off-road situation.












Both connecting lock n roll products are a great addition to my project roof top tent, utility, kayak mounted, Solar energy equipped overland adventure trailer. Not only has my travel range increased due to this go anywhere upgrade, but my trailer security and its value has increased also. I am a very happy customer. So.e fab work may be necessary.


Some of the backroads we drive look more like a riverbed, and we worried about the twists and turns on our conventional hitch. The Lock N Roll hitch eliminates that worry. But the best part is the ease of hook-up. The Lock N Roll hitch is more forgiving in hook-up angle, and no more beating on the trailer mechanism to get it to grip the ball. Good heavy-duty product.


Very secure and solid!! It keeps your trailer tight with no shifting like a ball mount. It also allows for hooking up from any direction if you get boxed in by another vehicle. I was boxed in and only could attach from an angle and not straight in. A life saver!!!


This is the best hitch! Super durable, easy to use and secure. Really well build solid. Is super heavy which shows the quality

Let me just tell you that I got rear ended while the hitch was on ….short story nothing happen to my car or the hitch, but the person that rear ended me, well that’s a different story


This hitch has made it possible for both our Subaru Outback and our truck to pull our small RV. It was a good price for an invaluable piece of equipment!


The Hitch as exactly what we needed as our new vehicle was a bit lower and we need to have the extra positions to get the correct height. The hitch has performed as expected...great product, we love the hitch.


The articulating hitch system has worked great for my offroading needs. I've got a Rubicon and have no worries about taking my a Smittybuilt Scout trailer off the beaten path and finding some great dispersed camping spots.


This new set up has resolved a long time issue with my overland trailer and tow vehicle.


The product is great. Just wish etrailer’s return process was a bit more frictionless. Having to call costumer service to get a return approval, address, and being threatened with a 20% restocking fee as well as being charged for shipping. After ordering five products from over the past three months, I’m now convinced the local store, even if it’s within 100 miles is a better way to go, FOR ME.

  • Comparing Lock N Roll Hitches Drop and Rise
    The Lock N Roll # 336VS517 has a rise or drop of 4 1/2", and the Lock N Roll # # 336VS503505 has a rise or drop of 4 1/4". The main difference between the 2 Lock N Roll hitches # 336VS503505 and # 336VS517 is that the # 336VS503505 is adjustable. There's 3 different positions it can be mounted in the channel.
