Sturdy steel ball mount with a solid shank measures 9-3/4" from center of hitch pin hole to center of ball hole. Polyurethane interior acts as a shock absorber to reduce vibration. Powder coat finish protects against rust.


Good, very solid ball mount with just the extra rise I needed, 2 3/4", to get level trailer and good clearance for the trailer jack.
But excessive shipping charges from etrailer, $[XX] for an $[XX] purchase. Found out to my cost later that [online vendor] would have shipped for free.


As a full-time RVer, e-shopping is very important for us. etrailer was the right place to shop. Right product, delivered on-time for a great price. You beat the local discount RV store by $25 including shipping. At the same time, I had another outfit send me a clearly inferior product to the one they displayed. Said they would e-mail a pre-paid shipping label for the return (didn't) and tried to put the blame on Amazon.
Thanks etrailer for a great experience !


Does take some of the shock out of pulling my wagon I use to mice corn!


Already own one of these ball mounts and it is excellent. Got a new vehicle and needed a drop hitch/ball mount to tow a trailer correctly.



I love the product. I already had or own an ball mount and the convert a ball setup. That is the reason I purchase another one but with the four inch . I have and will to continue to recommend the product.


We used this on our 2012 Sienna AWD to pull the largest single axle closed top U-Haul trailer to move furniture and bikes 400 miles through the mountains of PA, WV, and VA with no trouble. I noticed less jerking from the hitch being transferred to our van than the last time I towed a trailer like this (though that was with a large sedan). Easy to install and seemed to have decent tolerances in regards to fit and finish. Definitely increased my confidence in towing with a light duty vehicle.


Everything arrived and was in good shape. The cushioned hitch worked really well as I use it to pull a parade wagon with a bunch of musicians on it. The previous hitch bounced enough that they complained about it. This hitch does a good job of dampening the start and stops. Everyone's happy and the music goes on!



Still works well and the music continues.


These cushioned ball mounts are awesolutely awesome. I don't even know my trailer is behind the truck unless I look. They eliminate all the slamming and jerking of your tow vehicle you get with a regular hitch. I sold all my regular hitches and only run with cushioned ball mount hitches. I have the 2" and 4" drop mounts. I won't hesitate to buy a 6" or 8" drop cushioned ball mount should I ever need one. Do your tow vehicle a big favor and get one of these. You'll be glad you did too......


purchase to tow motorcycle on vac. this ball mount is built very well. it stopped the bounce on section lines in the road. also works well with brake controller. does not affect backing. stopped metal bang at startup.the only concern about the reciever stem doesn't seem to go as deep into the reciever. its still secure just sticks out further


Nice product, would definitely recommend if you do a lot of towing.


This is my second bar with shock absorber I've purchased from etrailer - I really like how they function especially when stopping and starting .

Chaz S.


Still working well. No issues. I do need to unload my older one that is to much of a for the f150. Thinking Craigs list or something.


I am using the convert-a-ball with a 2 5/16 ball to pull a tilt bed car trailer. The 4 in. drop levels the trailer to perfect. There are no sharp jolts loaded or empty because of the cushioning effect. Great product.


Will never buy another hitch without the cushion. It saves wear on the transmission jarring, and greatly smooth's out the ride. I actually will be ordering more for pulling wagons on the farm, as this one it ordered is set-up for the trailers with 2-5/16" ball.

Definitely would recommend to anyone who pulls a trailer.


Would not tow without one. I have overloaded on private property numerous times, and it still has not deteriorated the cushion. Makes regular towing much smoother. This unit, rated at 10k, with about 7500 lbs behind it, made my trailer feel a lot nicer then it is. If you spend big money on a trailer, no reason to use anything but these cushioned mounts.


Works great. Very happy with this hitch.


I have several of the convert-a-ball cushioned hitches!!! They are very strong and provide a cushion when starting and stopping. This lessens the shock to your vehicles drive train and makes your vehicle ride a little more smoothly and you feel less vibration from your trailer or whatever you are towing. I have visted their plant and seen their quality control. They test their products to the extreme!!!!!!!!!!! MADE IN THE USA !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!


I have used this product in the past. My new truck needed more drop. So I went from a 2inch drop to a 4 inch drop. I pull a 9500 pound boat. When I haul I have confidence when using this product. I like the idea of a cushioned hitch. I also use the convert a ball on the stinger.


I already had one of these cushioned ball mounts and bought a second so I can keep one with each of my trucks. Excellent product, noticeably quieter and smoother towing, and a high tow and tongue load rating. You get what you pay for.
E-trailer shipping time and customer followup are tops. I have bought a lot of items from them and never yet been disappointed.


I really like this ball mount as it really does quiet the noise and any jerking as it is cushioned, so has some give


eTrailer is the best! Fast ship and no problems
be using the heavy duty hitch to haul my 5,500 lb boat and trailer from Texas to Michigan this spring.


I am very happy with my purchase. Shipping on my items was very fast & packaged well. This hitch isn't the only item I purchased. I like all the items I received from you. Everything I purchased was made of very good qaulity material. And competative prices.
I would recommend buying from you to others !


This is these second time ordering a cushioned ball mount from etrailer. It's the best mount out there because when you're attached to a trailer, it feels as if it's not attached. No more bouncing around. Fast shipment and excellent packaging.


Very well built & seems to dampen the push n pull effect that my trailer has while hauling tractor & bush hog. Another great product from convert a ball..


The cushion feature in the hitch is great. For a heavy boat trailering it is a pleasant experience.


Great product and a Huge fan of the Cushioned Ball Mount System. Fast and simple. Excellent customer service received from E-Trailer! Package ordered shipped within the 3 days I selected. I would and have recommended E-trailer for their products. Thank you


It's what I was looking for.

  • Does a Ball Mount have the Same Capacity in Both the Rise and Drop Positions
    Yes, on a ball mount that can be used in both the rise or drop position such as # AMSC4 that you referenced, the capacity remains the same. For this ball mount it is rated for 10,000 pounds gross trailer weight and 2,000 pounds tongue weight. I have included a link to a video review of this ball mount for you.

  • What is the Hitch Pin Hole Diameter for Convert-A-Ball Cushioned Ball Mount AMSC4
    Convert-A-Ball Ball Mount for 2" Hitches - 2-3/4" Rise, 4" Drop - 10,000 lbs Item # AMSC4 does indeed have a 5/8 inch diameter pin hole. That is the standard size for 2 inch ball mounts. The standard size for 1-1/4 inch ball mounts is 1/2 inch. If you have a 2 inch hitch receiver then you will be good to go with this ball mount. But if you have a 1-1/4 inch it will not fit. Convert-A-Ball doesn't have a cushioned ball mount for 1-1/4 inch hitches.

  • Will a Cushioned Ball Mount Work with Surge Trailer Brakes
    The cushion inside of the Convert-A-Ball cushioned ball mount # AMSC4 would have only a slight affect on the surge coupler on your trailer. You may not even notice it. The cushion is very dense and the more pressure that is put on it the firmer it gets. It would take more force to compress that cushion than to actuate the surge coupler. Cushioned ball mount # AMSC4 has a 2-3/4 inch rise or 4 inch drop but there are other options if you need a different rise or drop to tow the trailer level: #...

  • Minimum Rise for Convert-A-Ball Adjustable Ball Mount CAB-UM
    The minimum rise for adjustable ball mount # CAB-UM is approximately 2-1/2 inches. But unless you tow multiple trailers and need the adjustability of this ball mount I recommend a fixed ball mount with between 2 and 3 inches of rise. Covert-A-Ball has # AMSC4HD or # AMSC4, both with a 2-3/4 inch rise, if you want a cushioned ball mount. If the ball mount does not have to be cushioned we have # C45155 which comes with a 2 inch ball installed and with a 2-1/4 inch rise. The ball is not...

  • Is it Okay to Use Cushioned Ball Mount with More Capacity than Needed
    It really doesn't hurt to have a ball mount with more capacity than needed. If anything it's just added insurance that the ball mount wouldn't fail. For 14k capacity cushioned ball mounts we have the part # AMSC2HD which has a 2 inch drop, part # AMSC4HD which has a 4 inch drop and part # AMSC6HD which has a 6 inch drop.

  • Will The Cushioned Ball Mount # AMSC6 Help Reduce Bounce On Coachmen Clipper Trailer
    The item you selected, Cushioned Ball Mount, part # AMSC6, will help a bit in any noise or bounce of the drawbar. The recommended rise and drop for a ball mount on your 2011 Volkswagen Routan is 2 inch rise and 4 inch drop. You will need to use Cushioned Ball Mount, part # AMSC4. Another thing that can contribute to the rough ride you are feeling is low tongue weight. The tongue weight on your Coachmen Clipper 1285 SST may be very low.

  • How to Pick Out Ball Mount for 2014 Toyota Sienna Towing Boat Trailer
    I wasn't able to find the coupler height of the trailer you are interested in so your best option would be to contact who you are buying it from and have them measure from the ground to the bottom of the coupler lip with the trailer level. When we installed the Draw Tite # 76112 on a 2014 Toyota Sienna like yours we found that it measured 12 inches from the ground to the top of the hitch opening. If you compare that 12 inch figure to the coupler height you get for your trailer you'll be...

    You could certainly use the Convert-A-Ball Ball Mount for 2" Hitches # AMSC4 together with the Curt RockerBall Shock Absorbing 2" Hitch Ball # C40047. Whether it is pointless or not is dependent on what you are doing or experiencing right now.

I have attached a very helpful video for your reference. This ball mount is rated at 14,000 lbs and has a shock absorbing center to help with bouncing and chucking. For a 2-5/16" hitch ball you can use part # 19286 with the ball mount.

  • Gaining Rise With a Hitch Ball
    You can get get a hitch ball with a 1 inch diameter shank that will give you 2 inches of rise with a 2 inch ball # C40034, though that is going to limit your towing capacity to 6,000 lbs. If you needed to stick with a 10,000 lb towing capacity, then you would need a new ball mount, # C45338 for 8 inches of drop, # AMSC6 for 6 inches of drop or if four inches of drop was needed, # AMSC4. I have added links to video reviews of each of these ball mounts for you to take a look at.

  • Measuring for a Ball Mount with the Right Rise or Drop for a 2008 Chrysler Aspen
    Ideally you would measure for the amount of drop needed in a ball mount with the 2008 Chrysler Aspen loaded because it will be closer to the actual towing situation. Since the vehicle is sagging with gear loaded in it, it is going to sag even more then the trailer is coupled because of the tongue weight of the trailer. What I recommend is weight distribution so that the vehicle does not sag and will provide you will better braking, steering, and visibility. To choose a weight distribution...

  • Recommendation to Help Back and Forth Movement in Trailer Hitch While Towing
    To help alleviate the back and forth chucking you are experiencing with your 2 inch receiver there are a couple of things I recommend doing.

I will list the different rise and drop available for this ball mount below....

  • Which Hitch Ball is Better, the Curt or the Draw-Tite?
    Both the Draw-Tite item # 63836 and the Curt item # C40030 will work with the Convert-A-Ball Ball Mount item # AMSC4HD. The 1/8" difference in shank length will not affect the function of the hitch ball. I recommend the Curt item # C40030 because it has a slightly higher capacity and it will save you some money.

If you're going to be towing up to 10000-lbs, the Convert-A-Ball # AMSC4 would be a great option that will help reduce some of the jerking and bouncing since it's a got some cushioning inside the shank that smooths out the ride.
