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.


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 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.


Other than picking the wrong drop, which is on me, this hitch system has been great. I was very happy to see that the system includes grease fittings on the articulating parts as well. Something that isn't very clear in the pictures both here and on the manufacturer's web site. If you are looking for a strong hitch system for an off road trailer, I would recommend this over a pintle and lunette ring system. No banging and no potential binding.


OUTstanding. Lift height was what I needed. Very easy to order, Nicole was super user friendly. Ask for Nicole everytime.....


The whole order showed up and it was all correct.


It will fit on A 2022 Jeep Wrangler And not interfere Would the spare tire or tailgate in the up orientation. I needed to Level out my Taxa Woollybear.


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.


Great product


Price gouging!


Looks like the real deal for off road. Yup its not cheap.


Went camping with my Jeep and it worked amazing!!! Great product. Thank you.


made from thick and sturdy material

  • Can I Back Up Normally When Using a Lock N Roll Trailer Coupler
    The 360 degree rotation of the Lock N Roll Articulating Trailer Coupler # 336VS511, along with the left to right and up and down articulation allows fantastic maneuverability, especially when backing a trailer around a corner and into a tight spot.

  • Does Lock N Roll Articulating Hitch part # 336VS511 Reduce Weight Capacity
    When using an articulating hitch like the Lock N Roll part # 336VS511 there is no reduction in weight capacity on the hitch or the trailer when compared to a ball mount. If your truck has a 5,000 lb weight capacity and the trailer you are getting weighs 6,600 lbs the only solution is a different truck with a higher towing capacity.

  • 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...

  • Will Lock N Roll Articulating Coupler Fit 2020 Sunset Park Traveler
    From what I can tell based on the photos I looked up of your 2020 Sunset Park Traveler it does have an A-frame coupler on it so as long as the frame is weldable then yes, you can use the Lock N Roll Articulating Coupler - A-Frame # 336TS504.

  • Which BOLT Lock Can be Used with 2016 Toyota Tacoma
    Yes, the BOLT hitch lock part # BL7023584 does work with the key of your 2016 Toyota Tacoma that unlocks the tailgate. This lock has a usable width of 3.55 inches which would be more than enough to be used with a Lock N Roll Articulating Hitch like # 336VS511 as the shank of the Lock N Roll is same width as any standard 2 inch hitch accessory.

  • Usable Span and Diameter of Replacement Pin for Lock N Roll Articulating Hitch for 2 Receivers
    We don't have a pin lock that would replace the pin of the Lock N Roll # 336VS511 that you referenced but if you found a 1/2 inch diameter pin that has a usable span of 4-3/4 inches that would work since the replacement pin # 336HP001 has these dimensions.

  • Converting Pintle Setup of M416 Stevens Military Trailer to Lock N Roll Articulating Coupler
    Since your Stevens M416 has an A-frame design the correct coupler setup you'd need for your trailer to use a Lock N Roll Articulating Coupler would be the part # 336TS504 which was designed for A-frame trailers for a direct fit that won't extend the trailer tongue. This would have to be welded on which I am sure you wouldn't have an issue with. If you were really wanting to extend the tongue of the trailer out though you'd have to use the # 336TS508 instead and find someone willing to...

  • Axle and Other Towing Part Recommendations for Small Overlanding Trailer
    For your application I recommend going with the Timbren Heavy-Duty Axle-Less Trailer Suspension - Straight Spindle - Off-Road Tires - 3,500 lbs # ASR35HDS01. This uses independent rubber suspension which is extremely popular among the off-roading community as it gives your trailer a much more stable ride quality. To add brakes and a hub/drum kit to this you'll need the Brake Set # 23-458-459 and Hub/Drum # AKHD-655-6-EZ-K which has a 6 on 5-1/2" bolt pattern. Since you're wanting to use...
