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.

Fast delivery, very good heavy duty 4" drop hitch 692731


I like the “no bang and jerk “ you have with solid hitches-should be easier on the pin and hole 576633

Hauled 12 loads~6 yards ea with bumper pull gravel trailer-worked great-no noticeable wear

Great product 491961


These cushioned ball mounts work perfectly. I had a 2" drop version that I used for a couple years. Purchased this 4" drop due to trailer height adjustment. 454887

This unit continues to work perfectly. It connects our car hauler trailer to our motorhome and gets about 10,000 miles a year of usage
Norm M - 11/26/2018



I just received my ball mount receiver and ball. Great looking product. I'm excited to see how the cushion works. Torqueing the ball to 450ft lbs. was fun!!! 331265


This was my second order from Etrailer. I am very pleased with the quality of this product it appears to be built very well. etrailer came through once again and got my order to me very quickly. Once I tow my 10000lb car hauler I will add to the review. 200701


Fantastic! I've used these before with lighter truck/trailer combos, but the difference with a heavier truck and trailer is even more amazing compared to a non-cushioned ball mount. 199150


This is the second hitch I own. Previously, bought the 2 inch drop and I wanted the 4 inch drop. The hitch works great! 160839


This is a very good quality drop hitch! 126313


This receiver is built like a tank !! 68421


Very pleased with service and product. Thanks very much. 55546


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

  • 14k Capacity Ball Mount Options
    The ball mount part # AMSC4HD has a 14k capacity and is designed to fit a 2 inch hitch. This ball mount has a 2-3/4" Rise/ 4" Drop. For a hitch ball you would want the part # 63836 as it has a 14k capacity as well and is a 2-5/16 inch hitch ball. Or for an adjustable ball mount that can do various rises/drops you would want the part # AM3298. I attached a help article on how to pick out the correct rise/drop ball mount as well.

  • 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...

  • Recommended Cushioned Ball Mount That is 10 Long and 4 Of Drop
    We do have a cushioned ball mount with 4" of drop and 10 inches from the center of the hitch pin hole to the center of the ball hole with part # AMSC4HD. 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.

  • 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.

  • 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...

  • 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...

  • 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...
