Rigid Mount Design

This rigid-mount coupler fits tightly within the channel bracket (sold separately) for a secure and rattle-free connection. Four mounting bolts with nuts are included for installation.


Hexagonal Grooves

Hexagonal grooves are cast into the inside of the coupler's channel to hold the nuts in place for you as you tighten the bolts down when mounting the coupler in your trailer's channel bracket. This not only makes installation faster and easier, but it also allows for a tighter fit that eliminates movement and noise. It also reduces any jolting that occurs during acceleration and braking.


Collar-Lok Connection

Collar Lok

The ball-and-socket joint of the coupler keeps the hitch ball captive by providing a continuously tight fit. Within the socket, the ball retains full range of motion so that it can rotate in any direction to keep your trailer from binding up.


To hook up your trailer, simply lower the coupler over the hitch ball and close the hinged latch around the ball. Then slide the Collar-Lok over the latch. When the collar is in place, it not only protects the hinge joint, but it also gives you visual assurance that the latch is securely closed. As a final step, slide in the coupler pin. This pin is chained to the coupler so you won't lose it. Because the pin hole is angled instead of being straight up and down, inserting and securing the pin is easy.


Spring-Loaded Hinge

Simply reverse the steps to unhook your trailer from your tow vehicle. Slide the pin out and push the Collar-Lok back.The spring-loaded hinge will pop open for a quick release. A built-in stop tab will keep the jaw from flinging out too far as the coupler opens. The stop tab is a unique addition that prevents the hinge from overextending.


The latch has a force-transfer feature to add stability as the ball is forced against it on bumpy roads. This keeps the hinge joint and latch from breaking or torquing to extend the life of the coupler.


Downward Bias

The downward bias of the coupler improves the angle at the articulation point and allows for a better connection with the hitch ball. The result is better support for heavy loading and a nice, streamline look.

I have bought a few of these over the years for all my trailers. I have never had a problem with Bulldog couplers. They have updated the design on this one. The rear channel casting has hex insets cast into the channel. It uses (4) bolts instead of (2). This makes it nice to adjust height and easier to get the bolts thru. It is also nice because it does not have to deflect the channel so much to get tight. Really like the changes and the quality is still great.

It take a bit of getting used to, but you can certainly tell this is a best in class hitch. I pulled my 2006 crew cab longbed 7500 lbs. truck across the country on my PJ car hauler...

Once at new home I used trailer\hitch to haul 4klbs. - 5klbs. of fence material - no worries...



by:

Quality product as I thought it would be. First time order from etrailer, timely shipping.

Still very pleased.

Ordered my adjustable bulldog coupler for my trailer so I could get rid of my pintle hitch.Got upgraded on my shipping for free. Coupler arrived ahead of schedule. I'll definitely be doing business with etrailer again.



by:

This coupler is super strong. The weld is of excellent quality and the piece itself is nice and heavy duty. Just make sure you keep it lubricated with good old wd40 for the sliding collar and the opening mouth and this thing will work every time. I used this to replace that sloppy píntle ring on my trailer and I am extremely happy I did !!!



by:

Much better than the stock hitch. Good quality manufacturing.

Five star service from etrailer, and maybe a two or three-star product from Bulldog. Aside from the rust and the fact that the collar is so stiff that it can't be operated by hand, the fabrication on the steel attachment plate is poor. The holes for the tongue jack are punched out, twice in some cases, resulting in an enlarged hole, but there are no threads for the tongue jack so you'll have to fumble around and use nuts underneath. The vertical angles on the steel are wrong, so it will splay out at the bottom and won't fit tightly to the A-frame and you will need to shim it out. The interior of the casting is full of weld spatter that will chafe the tow ball. I bought the less-expensive Ram sleeve-lock coupler under a Curt label and the fabrication is much better, having none of the problems the BullDog did. etrailer kindly sent me an RMA to return the BullDog.

The best coupler we have used for our construction business. I have been using these for 14 years now without any problems. We replace them every 5 years at about 160,000 miles when we purchase new trailers. I currently need three now but they have been out of stock for several months. Still waiting for new stock to arrive so I can order. I feel safe with this type coupler and my employees also like the security it provides.



by:

Don’t buy this!!! It literally does not work. You can’t open the coupling because it was built incorrectly. There isn’t enough room to slide the coupling back. Of course I didn’t realize this until I had mounted it on my trailer. etrailer customer service is about to get an earful!
