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.

  • Dimensions of the Lock N Roll Articulating Adjustable Hitch
    I spoke with my contact at Lock N Roll about the Lock N Roll Articulating Hitch part # 336VS503505 and they were not quite sure what measurements you are looking for nor was I. That said, I went out to our warehouse for you and jotted down a few dimensions on the above in hopes these were what you were looking for. If it is not please try to further clarify this for me and I would be happy to remeasure this for you. I have attached a photo below with the dimensions I think you are looking...

  • Choosing the Correct Rise/Drop for Lock N Roll Articulating Hitch
    The # 336VS503515 comes with the adjustable channel bracket along with the adjustable channel mount and bolts. You will need to install the channel mount in the appropriate rise/drop position since it does not come fully assembled. It looks like you already have a complete Lock N Roll hitch so you actually don't need the # 336VS503515. Instead, you could get the # 336TS515 to replace your existing channel bracket. You can remove the # 336VS503 on your current Lock N Roll and install it...

  • 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.

  • Recommended Lock N Roll Articulating Hitch For Scamp Trailer
    For your Scamp trailer, the Lock N Roll Articulating Hitch - Adjustable Channel Mount - Vehicle Side - 11,000 lbs # 336VS503 will work with the Lock N Roll Articulating Trailer Coupler for 2" Receivers - Trailer Side - 11,000 lbs # 336TS510 you mentioned but I don't believe that is the best option for your trailer as that could involve cutting and welding. Instead, I recommend the Lock N Roll Articulating Channel Tongue Trailer Coupler - 3" Channel - Trailer Side # 336TS508. This will...

  • 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!

  • Recommended 2-1/2" Channel Mount For The LockNRoll Articulating Hitch 336VS503
    The B&W Tow and Stow line of ball mounts, including the # BWTS20049B, will be too wide for the Lock N Roll # 336VS503 to fit around, so I can say that one is a no go right off the bat. With that out of the way, the # 336VS503 will fit in the channel of the BulletProof Hitches # HD256. You will still be limited to 11,000 pounds of capacity as this is what the # 336VS503 is rated to. As a side note, we do also have the Lock N Roll 5-Position Adjustable Channel Bracket # 336TS515 that will...
