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.

. Clever design and super heavy duty. This is one thing you wont have to worry about breaking



by:

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.



by:

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.



by:

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.

Seems like a good item. My problem is that it didn’t come assembled or even with the proper bolts or locking pin like shown in the picture or in the video like they said it did. When I called customer service, the representative kept asking where does it say that it does come with those items instead of helping out and seeing that it should come with it. Next time I will order it directly from the manufacturer. Terrible customer service.



by:

A little disappointed that this didn’t come with the pin or any of the hardware to assemble or use this hitch. Even though in the pictures those items are there. I’ve ordered from the manufacturer directly before for another vehicle, and the pin and bolts were included.



by:

Easy to work with, very effective. My sole caveat: 360 degree articulation means your off-road trailer can, and under the right circumstances, will flop on its side (ask how I know).



by:

Hitch has been solid and works well with my lofted truck. I am basically living in my off-road camper and see rough roads and trails every week. No complaints after a year of use.

  • Is There a Trailer Coupler Designed For Offroading
    There is a trailer coupler designed specifically to be used for offroading, from Lock N Roll. This uses an articulating connection between the coupler and accompanying hitch mount that gives a full 360 degree rotation between the two. So the trailer won't bounce off a hitch ball as you go over uneven surfaces as there isn't a hitch ball in use. You can use either of the following couplers, depending on if your trailer has an A-frame or 3" channel: - Lock N Roll Articulating Channel Tongue...

  • 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. The holes are spaced 2" apart, so 4 1/4" is the lowest and highest setting, about 2" for the middle position, no drop or rise at the third position. The # 336VS517 is not adjustable...
