The couplers (3) are of excellent quality. Ordering was very simple by telephone. All questions were answered. Shipping was immediate and the product arrived in an unmolested box which surprised me due to the weight. I expected the box to be dented and the corners smashed. Tracking of shipments was important to me. Couplers will be installed on a rather unique vehicle. Each of the three cars of this miniture train will receive the new couplers.

Bull dog has been a great hitch. One time I pulled a load upwith a five ton comealong.while winching I noticed the trailer touched the ground needless to say the truck was in the air.the tounge is rated for seven thousand, the load weighted eight thousand six hundred pounds plus the trailer. What a hitch. The only draw back I wish the insert for weldingis a little short for my preference. Wish was about three inches longer. Thanks

Just what I needed and couldn’t find at local stores. Great price.

Review from a similar Collar-Lok Coupler in Straight Tongue Trailer Coupler


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.

We hate to see rust and other complications when it comes to the products that we sell. I have sent this information over to our customer service team for them to contact you.

Review from a similar Collar-Lok Coupler in Straight Tongue Trailer Coupler


The Bulldog coupler is SO MUCH easier to hitch up and disengage than my previous coupler which required several back and forth movements of my tow vehicle to engage/disengage the hitch ball.

Review from a similar Collar-Lok Coupler in Straight Tongue Trailer Coupler


A great product. The original crappy hitch on our new trailer was always a real pain to unhitch. Typically would have to keep the trailer wheels chocked and let the tow vehicle (no brakes and in neutral) roll forward or back freely while raising the tongue - only then would the ball be released from the ball socket. Not good when on a slope. A few times we actually had to pull out the 5/8" ball mount pin and drive forward and let the ball mount slide out of the receiver. No issues at all with the Bulldog hitch. And it's nice to have the positive and easy-to-verify clam-shell hitch mechanism instead of the sliding yoke lock of the original hitch. $200 bucks to have the old hitch torched and ground off and the Bulldog welded on. Money and time well spent.

Review from a similar Collar-Lok Coupler in Straight Tongue Trailer Coupler


Really fast shipping, install only took 15 min, and much more solid than the original coupler on the trailer that used two long bolts (which wore and caused the holes to get oblong making the connection to the trailer sloppy), as compared to the four bolts provided with the new coupler.

Review from a similar Collar-Lok Coupler in Straight Tongue Trailer Coupler


Solid coupler a good company. The coupler doesn’t have any mechanism to assist in sliding the collar back but I welded on to nubs to pull it back with. I wanted several Master disk padlocks keyed alike but Etrailer could not get those for me so I went with a different online trailer co. that offered a six pack of them at a good price.

The collar hitch was put on my home made trailer and we use it 2-3 times a week. It is smooth working and easy to hook up. Thanx

Review from a similar Collar-Lok Coupler in Straight Tongue Trailer Coupler


After purchasing a trailer that came with a Collar-Lok coupler standard, we decided to swap out more of our standard couplers over to the this style. So far this product has held up very well. The only downside is the finish/coating is a bit cheap and it started showing corrosion within a few weeks.


Comments
What I recommend is touching up the coupler with a rust resistant spray to help prevent rust.

Review from a similar Collar-Lok Coupler in Straight Tongue Trailer Coupler


I bought this old really cheap to rebuild. One of the parts that had to be replaced was the hitch, I towed it home with my fingers crossed. I googled trailer hitch, trailer and etrailer was one of the sites that was suggested. I had to find a hitch that fit the 3 1/2" pipe that was the tongue, voila there it was to my amazement. I ordered it right then, 4 days later it was delivered yesterday. Today I mounted it, it was an easy installation and I am really pleased with the hitch and install. My fears of losing a trailer are now history, tomorrow it gets tested with 1 1/2 yards of gravel for the slab for my new. shop

Works great. Welded it on and was ready to go. Have ordered from etrailer before, and just like every time before my parts arrived very promptly and have never had any complaints with service. Will definitely be using etrailer again.

Product was exactly as advertised, and got here earlier than expected. I plan to use it on an old pickup truck frame which I am converting into a pull behind trailer. Staff very helpful and efficient.

Review from a similar Collar-Lok Coupler in Straight Tongue Trailer Coupler


Fast two day delivery and for the best of all shipping charge…FREE! The bulldog coupler works perfectly and look beautiful after welding, cleanup, priming and painting black to match my trailer. And the bulldog mechanism looks solid as a rock and idiot-proof (impossible to hitch wrong) when hitching up to the 2” ball. I just returned from having it welded to the trailer tongue after ditching the cheapie $xx trigger coupler (it came with the trailer) that was an accident waiting to happen. I look forward to many years of flawless performance.

Review from a similar Collar-Lok Coupler in Straight Tongue Trailer Coupler


I have a 2003 Jeep Liberty CRD. The spare tyre of the Liberty means the standard tow hitch is on a long bar to clear the spare tyre. I wanted a low profile coupling so I could bring the hitch point in closer to the rear axle to improve the towing characteristics with a 5000 lb trailer. One photo shows my old set-up and the other with the Bulldog. This coupling was ideal.

Review from a similar Collar-Lok Coupler in Straight Tongue Trailer Coupler


LOVE this Bulldog hitch! I welded it to my new custom built motorcycle trailer and I will never go back to the other kind again. So much easier to get a positive connection. I also like the integrated lock hole in the latch. It's definitely worth the money.

Review from a similar Collar-Lok Coupler in Straight Tongue Trailer Coupler


This is a perfect replacement for the one that broke, first of all my trailer was stolen, thanks to Las Vegas Metro police department they recovered it. The genius's that stole the trailer didn't understand how this coupler worked and it must have come loose. This was a perfect replacement, I cut the old one off, installed the new coupler, and my trailer is back to normal, in fact it's loaded up for a very large job tonight.
