Shock Absorbing Ball Mount

Cutaway views of the ball mount shank showing the polyurethane cushioning

Convert-A-Ball ball mounts are designed with a polyurethane interior that helps to absorb road shock to limit bouncing and vibration while you tow over rough terrain. It also reduces the slamming and banging that occurs during stops and starts. This helps to protect your vehicle's driveline, your hitch assembly, and your trailer's contents while you're towing.


This Convert-A-Ball ball mount meets or exceeds THMA V-5 ratings in all categories and meets SAE standard J-684.

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. 316710

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.

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...... 178866

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. 567923

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! 522872

Still works well and the music continues.

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. 283369

Ask the Experts about this Convert-A-Ball Trailer Hitch Ball Mount

  • 10,000 lb Capacity Ball with 1 inch Shank # 901B Recommendation for a Cushioned Ball Mount # AMSC4
    This Cushioned Ball Mount, part # AMSC4, has a ball mount hole that measures 1 inch in diameter. If you are looking for a ball with a 1 inch shank that also has a 10,000 lb capacity I would recommend the Convert-A-Ball Interchangeable Ball Set, part # 901B. What is also nice about this ball set is that it comes with an interchangeable ball that can be swapped from 2 inch to 1-7/8 inch quickly and easily and should work very well for you.

  • Anti-Rattle Recommendations for Convert-A-Ball Cushioned Ball Mount # AMSC4
    We do have some anti-rattle locking pins that will fit the Convert-A-Ball Cushioned Ball Mount # AMSC4, but the Lets Go Aero Anti-Rattle Device and Lock # 63232 is not compatible as it needs a hollow shank to fit properly. The Tow Ready J-Pin Stabilization Pin # 63201 will fit this mount, however it requires a specific type of hitch to ensure a secure fit. I have included a graphic showing what this hitch looks like. I have included links to video reviews of this item. Another option...

  • Long Shank Ball Mount for Added Clearance While Towing
    I'm assuming that you are asking about length of the ball mount and not the drop or rise. The Convert-A-Ball Ball Mount for 2" Hitches # AMSC4 is 12 1/4 inches in length from the end of the shank to the center of the ball hole, and 9 3/4" from hitch pin hole to the hitch ball hole. If you are needing a longer ball mount than that to have additional clearance we do have other options. For a fixed ball mount that has close to the same ratings and rise and drop measurements I recommend...

  • 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...

  • Shock Absorbers in Convert-A-Ball Cushioned Ball Mounts

  • How to Pick Out Ball Mount for a Land Rover Discovery 3
    I attached an FAQ that details how to pick out the correct ball mount. Picking out the correct ball mount will allow your trailer to sit as level as possible. Basically you will first measure the height from the ground to the top of the receiver opening on the hitch while on level ground. Next, you will measure the coupler height from the ground to the bottom of the trailer coupler when the trailer is on level ground. Next, you will need to compute the difference. If the hitch height...

  • 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.

    All of the aftermarket hitches we offer for your 2014 Ford F-150 also have the same 2-inch size receiver tube and this is the size that is compatible with the cushioned ball mount you referenced, Convert-A-Ball # AMSC4. When choosing a ball mount you need to match the size, of course, but also the Class Rating (Class IV or Class V for the hitches we offer). You also want to choose a ball mount that has the correct amount of rise or drop to allow your trailer's frame to remain level...

  • 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. First is to use a cushioned ball mount, the Convert-A-Ball, which is designed to reduce this type of movement and additional road shock with its polyurethane cushioning interior; if you take a look at the accompanying diagram it displays the cushioned inside of the ball mount. I will list the different rise and drop available for this ball mount below....

  • 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. Proper loading of the trailer, with heavier items...

  • 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...

    Thank you for your recent purchase of the Weigh Safe Stainless Steel Hitch Ball w/Built-In Scale # WSUN-1. The specs for this item indicate it WILL fit on a ball mount with a 3/4-inch thick ball platform. But if you need a different 2-inch ball mount with 4-inches of drop that is confirmed to have a 3/4-in thick ball platform I recommend cushioned ball mount # AMSC4. I measured this item in our warehouse to confirm the platform thickness is 3/4-inch. It is rated for 10K, like the hitch...

  • Ball Mount Rise Recommendation for Towing K2 Mighty Mule Trailer with 2017 Toyota Rav4
    So the coupler height of the K2 Mule trailer part # K2MMT5X7 is 16 inches from the ground and then the Draw Tite hitch part # 75235 has a height of 13 inches from the ground to the top of the hitch opening. That means you would need a rise ball mount of 3 inches for the trailer to sit level. The part # AMSC4 has a rise of 2-3/4 inches so it will be close enough to work very well. For a 2 inch ball like what the k2 trailer requires you would want the part # A-90.

    As you mentioned in your question, the Reese Sway-Control Bracket # RP26003 requires the ball mount platform it is used with to be narrower than 2-5/8 inches. I narrowed down our available selection of ball mounts to those that meet your requirements (2 inch hitch, 4 inch drop, 1 inch ball hole, 7,500+ pound capacity) and then went out to our warehouse to measure the ball platform widths on these units. I found that the following ball mounts match what you are needing and feature a...

  • 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.

We also have the Cushioned Ball Mount 2-3/4 inch Rise or 4 inch Drop, item # AMSC4. If you need a higher rated ball mount for your towing needs the # AMSC4 ball mount has a 10,000 pound capacity.

    The Draw-Tite # 2753 you were looking at should work just fine for you as long as the trailer won't weigh over 7500-lbs fully loaded. 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. Both of these ball mounts take a hitch ball with a 1" shank diameter, so if you've got a 2" coupler on the trailer the 2" Hitch...
