OK. Just installed the convert- A - Ball Multi -Cushioned Coupler this morrin. Took about 15 min. Took it for a test drive down the I10 just a mile from my front door. [ Casa Grande AZ.] It reduced the felt bumps and road jars by about 80%. I drove down the access road for a few miles. [ uneven, repaired spots, really ruff road.] Then got on the I 10 and drove between The Pinal exit and the McCartney exit. # lane just repaved about a year ago. Did not feel any road vibration that you get at 70 MPH. Other coulper go for 2 to 3 times this much. And require a lot of up keep. I would recommend this to anyone hauling horses,or any big trailer that whats a smoother ride.



Are you still satisfied with your convert a ball hitch.I am thinking about purchasing one for my living quarters.thanks pat.


Got stuck several times. Would not release. I finally had to cut it off. Cheap locking mechanism.


Works good


This hitch assembly is far better than the slide catch original equipment. Very easy to latch and unlatch with the benefit of being shock absorbing. Well worth the price!


This was a nice replacement for our BullDog coupler that was over 15 years old. The locking and unlocking mechanism is very smooth. However the rod that is supplied to reach into the bed is very awkward to use.


I cranked down on the bolts on my trailer and it still slipped in the tube. Be sure to drill through holes and put a hitch pin in it if you actually haul any weight. I love the ball lock mechanism, but I use a lock to ensure it doesn't come unlocked by something in the bed of my truck. The cushion part seems to damper some of the jarring when hitting bumps with the trailer.


This addition to the trailer has been wonderful. The trailer pulls as smoothly as anything I’ve ever pulled. I have noticed a decrease in the bumping when coming to a stop, and when accelerating for a stop. I would definitely recommend this to anyone wanting to smooth out their ride a bit.


this coupler does not have any holes to mount it.trying to drill 3/4 " holes is not fun.they call it cushioned but did not cushion it much.another problem is you can't see the ball to hitch it on a crew cab short bed.I ended up buying a B&W companion 5th wheel hitch.Pulls much better,and easy to hitch up.that is what you get buy trying to take a short cut.


Here are some Pros and Cons that I have on this Coupler. Mind you I have only taken the trailer for a short test drive with an empty Four Horse Trailer with Living Quarters. Trailer is 32.5 on the floor and has always ridden rough when there are no horses in the trailer, smooths out as the number of horses increases, loading up the axles on the trailer.

Design-I like that it does not take up a lot of room in the bed of the truck compared to other units. We are always hauling extra Hay/Feed and supplies in the bed when we are going to a Horse Show so like that I did not loose any bed space.

Craftsman ship-it is made extremely well, high grade steel, welds are very good, solid design

Locking Mechanism-Very easy to move the lock handle. Though I'm not sure why they give you a handle to lock and unlock it if you are using your safety chains as you should be. You are still going to need to get into the bed of the truck to attach the chains so might as well lock it while you are there.

Ride: I was hoping to give this Coupler a very high review but I did not get the results I was looking for in regards to ride from the item. I did not do a back to back comparison with the old Coupler vs the new one, but it seemed to buck just as much going over bumps with an empty trailer. I'm sure the ride will get better with horses on the trailer and it is probably helping with wear and tear on the truck and trailer taking up some of the road shock. I used to drive a truck with an air bag system hitch so I am comparing this to that. It was a very high end unit and was not looking to spend that kind of money again.

Locking Mechanism: I know I listed this as a Pro for ease of locking, but afraid it could be too easy. As stated before we like to haul items in the bed of the truck. It could be possible for an item to hit the lock arm and move it to unlock if you are moving around in a parking lot or driveway. I am going to mitigate this by putting a clip in the lock hole of the Coupler when attached to the truck.

Overall I think it is a nice product and looking forward to see how it does with full trailer. If your on the fence I think it may be worth the try. In the picture there is a custom spacer, not included with the Coupler.


My husband and I love this coupler. Product is exactly as described. Before installing the cushioned gooseneck coupler I could barely stand riding in the truck when we were pulling our new living quarters trailer. This cushioned hitch takes out the jarring . It’s like you barely know the trailer is back there. I would very strongly recommend this product. Thanks etrailer for the super quick delievery.


This is probably the way all gooseneck trailers should come from the manufacture. I put it on my 30 ft. equipment trailer for my transport business. The first job was 147 miles empty to pick up an excavator bucket & return the 147 miles. I pull with a Dodge ram 2500 4x4 Cummins turbo diesel. Amazing difference on driver comfort, cushioning to a degree that relieves the stress & fatigue i felt from the pounding before installing the CG i know is easier on the pickup as well. THANKS


This coupler is great. The cushion you get from the bushings is nice on long trips. I really like the way it locks to the ball and the way you are able to lock the coupler with a padlock, hooked to the truck or trailer just sitting.


Been using this for one year, very happy with it. It greatly reduces the vibration between the trailer and pickup. Extremely easy to hitch and un hitch! Well worth the money.


Perfect fit. Good amount of space available to adjust the overall length. I switched from a hidden gooseneck ball to a gooseneck ball that attaches to my fifth wheel rails. This raised my ball about 4 inches and the new coupler easily provided the needed adjustment.


This is the 2nd coupler of this kind we have had on our trailers. It always seems to give the trailer a smoother ride (which our horses appreciate) and I love the ease of the lock down latch.


Received my received today. Installed it with no problems and am looking forward to getting on the road and trying it out. I did drive a 48 ft living quarter horse trailer with this receiver 1500 miles and was totally impressed.
A well made product that is a great addition to any gooseneck.


No problems at all. Easy to install. I have it on a 42' horse trailer that I pull all over the lower U.S. states.

Works great, I have not had any problems.


I replaced the existing coupler on my 20' 14,0000# GVW flatbed trailer with this coupler. What a difference! I think it would be conservative to say that making this change has cut the jarring from the trailer to the tow vehicle easily in half. After buying the first one of these for my own use I ordered a second one for a conversion to a customer's trailer. What a simple fix for a very annoying problem!


I do think it seems more stable and smoother ride. We also put new tires on same time. Rides softer. Handles fine.


Super fast shipping and handeling. Hitch installed easily, haven't got a chance to tow the trailer yet.
This company is awsome, would definatly do business with them in the future


I recently ordered a coupler assembly for my gooseneck horse trailer. The service provided was outstanding in every way.


seems like a well made hitch easy install. Haven't pulled with it yet excited to test it out.


Best money I’ve ever spent on my trailer!

Seth K.


Still stand by my earlier statement, the best money Ive ever spent!


GREAT improvement! Easy installation, well made product. Really helped my horse trailer ride & pull smoother. Vibration & jarring is much less~ which reduces damage to LQ & makes horses happier.


Received my goosneck coupler fast.Communication from seller is outstanding,cept me informed ou what was going on,i like that.Have not yet installed the coupler but it looks very promising.Im trying to stop the bouncing and shaking too much.Just wish there was a better way to open and close the latch but this is not bad at all.Beats climbing in the truck everytime. THANKS.
