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.


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.


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


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


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.

  • How to Level Trailer With Lock N Roll Articulating Trailer Coupler
    I'm assuming you're speaking of a 2 inch drop on the ball mount you're currently using, is that correct? If so, the # 336VS503505 Lock N Roll articulating ball mount you'd looked at would allow for a 2 inch drop to properly level your trailer. The premise for a Lock N Roll is the same as for a ball/coupler. You want to put the vehicle side of the connection at the proper height so the trailer is pulled as close to level as you can get it. You'll also need the corresponding Lock N Roll...

  • Parts Needed To Tow Scamp A-Frame Trailer Behind a 1978 Toyota Landcruiser With Lock N Roll Hitch
    I recommend having the Lock N Roll Articulating Coupler # 336TS504 welded onto your Scamp a-frame tongue. Then you will be able to use the Lock N Roll Articulating Hitch # 336VS503505 on your 1978 Toyota Landcruiser to get the height matched up on your trailer.

  • What All Do I Need To Use The Lock and Roll Hitch System?
    The only difference between buying the Channel Bracket # 336TS505 and the Channel Mount # 336VS503 separately is only the fact that they are purchased separately. It's the same thing so grab whichever one saves you the most money. ON the trailer side you can use # 336TS502 but you will need the weld on channel bracket # 336TS516 to install the coupler. I've included some videos for you to watch!

  • Trailer Hitch Vertical Adjustment For Lock N Roll Coupler
    Vertical adjustability is not required on both sides. In most cases the trailer side is usually fixed # 336TS504 and the vehicle side usually has the adjustments # 336VS503505. As long as the trailer and towing vehicle are level these adjustments aren't needed. If you wanted to use the Lock N Roll Articulating Coupler # 336TS502 on your trailer side to get adjustments, you can weld something like this # 336TS518 on your trailer.

  • Can Lock N Roll Articulating Coupler and Hitch Be Used on a Trailer Traveling on Highways
    There aren't any speed ratings for the Lock N Roll Articulating Coupler # 336TS502 or Lock N Roll Articulating Hitch for 2" Receivers - 2-1/2" Drop/Rise - Vehicle Side - 11K # 336VS511 but it can be used safely at highways speeds without any worry. The Lock N Roll coupler simply provides the additional flexibility needed at the front of the trailer when towing off road by allowing the connections to pivot; this shouldn't come into play during highway travel and I would have no concerns...

  • Channel That Works With Lock N Roll Articulating Coupler
    I can confirm for you that the Lock N Roll Articulating Coupler - Adjustable Channel Mount # 336TS502 will absolutely fit in the Lock N Roll 3-Position Adjustable Channel Bracket for 1-1/4" Hitch Receivers # 336VS507. The coupler fits a 3" wide channel and it's mounting bolts are 2" apart on center, which is exactly the dimensions of the channel and mounting holes on the channel so it's a perfect match!

  • Can Lock N Roll Hitch System be Used with Disc Brakes on Trailer
    I reached out to my contact at Lock N Roll and he said that their system can be used with a surge brake application and that everything will function normally. The Coupler # 336TS502 would be the easiest to install if you have that type of surge brake system, but there are also the channel mounts for 2" # 336TS528, 2-1/2" # 336TS506, and 3" # 336TS508 channels if you're able to install one of those.

  • Recommended Articulating Coupler for Off-Road Adventure Trailer
    It sounds like you're looking for an articulating coupler. For the trailer side of the equation, use # 336TS504 for an A-frame coupler. For an adjustable channel tongue use # 336TS502. If you need a 2 inch channel tongue go with part # 336TS528, # 336TS506 for a 2-1/2 inch channel tongue, or # 336TS508 for a 3 inch channel. For the vehicle side, there are several different drops available. For a zero rise/drop, use # 336VS501. For up to a 4-1/4 inch rise or drop, use # 336VS503505 or...
