This ball mount is cushioned both vertically and horizontally, and you can move it up or down as needed to level your trailer. Simply pull out the pin to change heights. You can turn it over to use it in a rise position, too. Fits 2" hitches.


We bought this to tow our 3,000 lbs. boat with our Subaru Ascent with a 5,000 lbs. towing capacity. With the OEM ball mount, we could really feel every jolt and jiggle from hard stops, going over bumps in the road, and trailering down dirt roads.

However, the dual cushion ball has really improved our trailing experience. Once we get up to speed, we hardly notice we are towing our boat. It's also great because some of the lakes we visit are down dirt roads, and the cushion makes this a much more pleasant experience. I would highly recommend this to anyone towing a boat or larger trailer with a SUV as it maintains that comfortable ride and the jostling of the trailer is much less noticeable.


Rusted within 30 days. The manufacturer refused to warranty the product. I have continued to use it, but it has required some serious rust mitigation and is a flawed product.

To be honest with these type of ball mounts, rust would not be covered under warranty. I recommend keeping a rust resistant spray on hand to touch up the ball mount as rust will be inevitable given outside exposure.


A year has passed with my Convert-A-Ball Dual-Cushioned, Adjustable Ball Mount and I have nothing but praise for this mount. Once you find the correct height to have a perfectly level trailer there's no need to adjust. The beauty lies in the cushioning! Towing a Yamaha AR190 (3200lb boat and trailer combo) is silent. Even over the bumpiest pavement the tow is smooth. There is no harsh slamming when braking or taking off from the boat ramp. I don't know why everyone isn't running one of these, I wouldn't run any other hitch mount PERIOD! If you're on the fence, get off and buy one, you will NOT regret it!

Ive been using this mount since the summer of 2015 and love it. The bare steel inside is rusting and turning orange, but the mount works the same as I did day 1.


I needed an adjustable drop hitch to pull my new 13 foot Scamp camper with my F150 Raptor and this hitch does the job. As always with etrailer you get great service and the help videos are the best. Ordering from etrailer beats the heck out of driving all over town trying to find what you need and the fast and free shipping isn't bad either.



Still a Great Hitch, I traded trucks but did not have to trade hitches, very happy with it.


I received my order in a timely manner. Very pleased with the quality.

I have made two trips from Boston, MA, to Columbus, Ohio. Pulling my trailer with my Harley Davidson on it. I have been very pleased with the performance.


This hitch is superior to most adjustables in that it leaves more clearance underneath than most competitive brands (less dragging) when in the "drop" position. It completely solved the problem (dragging, gouging roadway in dips, etc.) when towing with my motorhome with a high hitch receiver. Also, it's considerably heavier duty than appears in the illustrations.


All is good but for two things. I got a lot of clucking towing my travel trailer around town. The last hole ,furthest away from ball end,I think was drilled of center. The pin that was supplied would not pass. Used pin from another hitch company,that worked.


Best trailer hitch I ever had. Takes away all the noise that is usually associated with ball hitches and makes you forget you are even towing.


I use this mount to allow for clearance of my boat windshield under my 7' garage door. When I'm towing I raise it to level, then I drop to the lowest point when landing it in the garage. It's also really quiet with the cushioned mounts. The paint doesn't really hold up to the raising and lowering, but this would be way more expensive in stainless. Overall great product. And it is made in the USA which is rare.


Good product. Very substantial (heavy) and functions as advertised. Etrailer has great information on it which helped me make an informed decision. The vertical receiver part could have a built in anti-rattle device which would make it even better with the cushioning. It could have a set screw or bolt or be rubber lined or something.
Overall great product and service.


I've had the cushioned draw bar on my Silverados for many years and love them. Brian from etrailer had this latest version to me 2 days after I ordered it, that was extremely fast . Thanks Brian ! This is for for my up coming 700 mile trip up North pulling a trailer with my sons new Side by side ATV. This trip should be a breeze with this new hitch. We haven't put the hitch on yet , but I don't forsee any problems
thanks etrailer for you're help !


Two problems with this item. First, if you have any play between your receiver and the shank of this mount, you can't use most solutions to stop that rattle as the shank is solid. Next, there's also movement between the vertical pipe and the horizontal shank, enough that there is noise while towing, something I wouldn't have expected from a cushioned mount. I wound up swapping this with the cheaper 80412 that doesn't have these issues.


Well built, quality welds, adjustability great for using this hitch on our truck car, and side by side.


Arrived in 2 and a half days and I live in Hawaii!
eTrailer staff were courteous and professional.
Hitch mount I purchased is well built and exceeded my expectations.


four stars because I have not used it yet,and not sure when I will.Not going to take the new truck out in the salt. It looks well made and has a wide range of settings,the reason I bought it. My experience with etrailer was easy ordering and fast delivery.


This is a very robust product. I am sure it would carry a heavy class III trailer load with ease.


Like the fact that I can move this hitch from my car to the wifes and set the hight to tow the trailer level.


The connection Between vertical and horizontal sections Does not allow the pin to be placed easily I had to use a hammer to force the pin IN place I hope after it gets some use it loosens up


Great adjustable hitch! Very easy to adjust and very sturdy (plus very heavy!).


Solid built. Fully adjustable. Great pr oduct!


It is a great produvt and takes all of the noise away. No more clanging and banging as before without the isolation


This product work very well towing my boat. Less jerking back and forth. Much smooth ride.


Been burnt before with online ordering, first time in a couple years Everything went smooth, appreciated having the status of the order updated all the way to delivery


The BEST!! Customer service goes above and beyond to assist with returns as well as determining the correct products to use!! THANK YOU!!!

  • Does Orientation of Convert-A-Ball Dual-Cushioned Ball Mount Affect Capacity
    The Convert-A-Ball Dual-Cushioned Adjustable Ball Mount # CAB-UM that you referenced can be used in either orientation to create up to a 7 inch rise or a 9-1/2 inch drop. Whether you insert the shank upside down or right side up, the capacities (5,000 pounds towing and 500 pounds tongue weight) remain the same. I have attached a short video demonstration that you can check out as well.

  • Could Convert-A-Ball Dual-Cushioned, Adjustable Ball Mount do 2 inch of Drop
    If you used the shank upside down with the part # CAB-UM you would get very close to a drop of 2 inches, but in reality it would be more like 2-1/4 inches. You'd have to flip the shank up side down but still use the ball mount platform where you insert it from below.

  • Can Convert-A-Ball Adjustable Ball Mount # CAB-UM Be Used with 5,000 lb Trailer
    Weight capacities are designed to tell you how much weight it can be used with and have it still be totally safe. The Convert-A-Ball Dual-Cushioned, Adjustable Ball Mount # CAB-UM has a 5,000 lb weight capacity. If you are absolutely sure you'll never be over 5,000 lbs this will work well for you and it would not be pushing it to the limit.

  • Will The Convert-A-Ball Dual-Cushioned Adjustable Ball Mount Clear My Tailgate?
    It seems like you're wanting to know if the Convert-A-Ball # CAB-UM will hit your tailgate when in the lowest drop position. When It is in the lowest setting it will sit 2-1/4" above the tube. Even in the lowest setting I don't think you'll have issues as it only sits about 6-7/8 inches from the tube. In rise position at the lowest rise the distance to the ball mount flange from bracket is 2-1/8" and the distance to the bottom of the tube is 10-11/16" In the highest rise the distance between...

  • What is the Diameter of the Adjustment Pin on Convert-A-Ball Cushioned Adjustable Ball Mount CAB-UM
    Convert-A-Ball Dual-Cushioned, Adjustable Ball Mount - 7" Rise to 9-1/2" Drop - 5,000 lbs Item # CAB-UM uses a 5/8 inch diameter pin for the adjustment part of the ball mount. This is the same as the regular hitch pin hole. The overall width at the adjust part is wider than the shank on the ball mount so if you are looking at locks I recommend # e98881 which has a useable span of 3-5/8 inches and you can order more than one keyed the same by selecting the keyed alike option on the page....

    I went out to the warehouse and pulled the Convert-A-Ball Dual-Cushioned, Adjustable Ball Mount, # CAB-UM, and took some measurements for you. The most critical measurement is going to be the measurement from the center of the hitch pin hole, to the back of the ball platform, which is 6 inches, and the measurement from the top of the receiver shank to the top of the ball platform, which is 8-1/2 inches, in the max rise position, see photo link.

  • Will a Cushioned Ball Mount # AMSC2 Benefit a 2000-lb Utility Trailer
    Cushioned ball mounts like the Convert-A-Ball # AMSC2 are rated for trailer weights up to 10,000-lbs but they will still provide a benefit when used with lighter and smaller utility trailers like your 2000-lb-er. These use a polyurethane insert that acts like a spring to reduce shock, bounce and vibration. Since your trailer weight is about 2000-lbs you could use the Convert-A-Ball Dual-Cushioned, Adjustable Ball Mount # CAB-UM rated for up to 5000-lbs. This adjustable cushioned ball mount...

  • Hitch Lock Set Recommendation for Convert-A-Ball Adjustable Ball Mount CAB-UM

This set includes two locking hitch pins with a 2-3/4 inch span (usable pin length) and an adjustable coupler latch lock to fit almost any size coupler, all keyed alike. When measuring the Convert-A-Ball Adjustable Ball Mount # CAB-UM, I found that the outer portion of the shank is exactly 2.52 inches. This means that you'll have minimal (less than 1/4 inch) play between the shank and the...

  • Can Convert-A-Ball Dual-Cushioned Adjustable Ball Mount Be Used with Weight Distribution System
    I do have a great solution for you, however the Convert-A-Ball Dual-Cushioned Adjustable Ball Mount # CAB-UM that you referenced cannot be used with a weight distribution system, in large part because of its adjustment hole spacing. Just about any weight distribution shank features adjustment holes that are spaced 1-1/4 inches apart, on center. The shank for the Convert-A-Ball features adjustment holes are are spaced apart by 1-1/2 inches. This simply means that the holes will not line...

  • Recommended Ball Mount with 7 Drop Over 5,000 Lbs
    The best option for a ball mount is one which is adjustable as this allows you to tow multiple different trailers assuming the rise/drop needs fits that of the ball mount. Furthermore, you'll need to go with an adjustable option anyhow to obtain the weight capacity you're after. I recommend the B&W Tow & Stow 3-Ball Mount part # BWTS10049B. It offers up to a 7" drop and has a 10K capacity.

The Convert-A-Ball in particular as you mentioned provides both up and down as well as side to side support via the polyurethane core.

It will however, not fit if you have lower rear fascia or a rollpan or tube bumper. It is a bolt on installation but does require some drilling.
