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.

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.

Video Transcript for Lock N Roll Adjustable Trailer Coupler 336VS503 Review

Speaker 1: Today, we're taking a look at the Lock N Roll adjustable hitch for the vehicle side. The Lock N Roll hitch lets you lock up your vehicle to your trailer. It provides the connection point for a Lock N Roll trailer side coupler. Trailer side couplers are sold separately and available at etrailer.com. Now, this unit has a four hole channel on it that bolts directly inside a three-inch wide adjustment channel. So I do have an example of that.

So this is Lock N Roll adjustment channel. It fits in there. You line up the holes, and then you bolt in there with the included hardware. This allows you to move the coupler up and down to ensure level towing. Mount holes are separated on center by two inches, and mounting hardware is included.Now, this coupler system is safe, it's easy to use, and it's one of the most versatile options available on the market today.

It's ideal for off-road use or for use over rough terrain. It works really well for pulling a trailer with your UTV or ATV. To get it ready to accept the trailer side coupler, we just need to take the clip off the pin. And so we lift that up, it pulls right off, and then we can take the pin out of the pin holes, move our latch plates out of the way, and then we can take our trailer side coupler, fit it directly in, bring the latch plates back over, and then we secure it by reinstalling the pin. And then we install the clip on the other side.So the latch plates when coupled offer a really nice, secure connection.

They actually lock in place. It also offers a visible connection point, which eliminates any question as to whether the trailer is hitched correctly. Also when coupled, you have 360-degree rotation and three axes of movement at the connection point. This mechanism right here is actually designed to be able to twist back and forth. And the reason why this is great, especially for off-road use, it really prevents twisting damage to the vehicle frame and the trailer frame that's caused by sudden changes in vehicle-trailer orientation.So it really compensates for all of that.

And instead of putting the stress on the frames, it's all right here in the swiveling joints. Also, this type of connection offers a wide range of motion. That allows you to couple and uncouple the trailer with ease. It's also helpful when backing a trailer around a corner and into a tight spot. It offers really tight, close-fitting connections to reduce shock and chucking. When you're ready to uncouple, you just remove the pin and clip, slide the latch plates out of the way, and then you can uncouple your trailer.So it's a nice system to use. It's easy to use. It's very secure, and it allows that wide range of motion. So overall, really nice, and again this is ideal for off-road use. It's made from sturdy steel construction. It's SAEJ6A4 certified. The product's made in the USA, and it is covered with a limited lifetime warranty. That's gonna do it for today's look at the Lock N Roll adjustable hitch for the vehicle side.

  • How Often to Grease Lock n Roll Articulating Hitch # 336VS503
    There isn't an exact schedule for how often to grease the Lock N Roll Articulating Hitch # 336VS503 through it's low profile grease fitting but maybe twice a year under normal use. It really just depends on how often you are towing and the conditions that you are towing in like winter weather, saltwater etc. The LMX grease like the part # L11390 is the toughest and most waterproof so that is what I would recommend.

  • What All Do I Need To Use The Lock and Roll Hitch System?

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.
