  • Will I See a Benefit Using the Convert-A-Ball Ball Mount for a 3,500-4,000 lb Motorcycle Trailer?
    Hey Mark! The Convert-A-Ball Ball Mount for 2" Hitches # AMSC4 will definitely make a difference due to the rubber insert that helps mitigate movement between the truck and trailer. You can check out all of the reviews on the page to see what others are saying about it with their specific setups! What are you looking to accomplish with the cushioned 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.

  • Where Are Fulton Ball Mounts Made?
    Fulton ball mounts, like the # F47CR, are made overseas in China. If you were looking for something American made, you would need to go with something like the Convert-A-Ball # AMSC4. The Convert-A-Ball will have a higher 10,000 pound capacity, the same rise and drop as the Fulton, and a polyurethane shock absorber that helps with the jarring/clunking felt when stopping and starting. This is made out of steel though, so if you wanted to go with an American made aluminum option, I do have...

  • 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 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: #...

  • Can the Curt RockerBall Shock Absorbing 2" Hitch Ball Be Used With Convert-A-Ball Ball Mount
    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. If you are getting/expecting a lot of bouncing, rattling, and vibration, then the combination will certainly help to reduce this. If you aren't, then it probably isn't necessary. Worst case scenario it isn't going to hurt anything, only help. My...

  • 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. You can purchase separate anti-rattle devices and hitch-pin locks. I recommend the trailer Hitch Wedge # MPG908 along with the etrailer.com Trailer Hitch Receiver Lock # e98880. Just know that there is the possibility of the No-Rattle Wedge nullifying the effects of...

  • Cushioned Ball Mount for Use in 2014 Ford F-150 Factory 2-Inch Hitch Receiver
    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 with...

  • Bumper Hitch For a 2006 Ford Cab and Chassis F-350, 450 or 550 and Cushioned Ball Mount
    It sounds like you are looking for the Buyers Products Flatbed Bumper Hitch Plate w/ 2" Receiver # 3371809055. This is designed to fit a 34" wide frame for a 2006 Ford cab and chassis F-350, F-450, or F-550. If you have a different vehicle please let me know as that is what I saw entered for a vehicle. Using a Convert-A-Ball Ball Mount # AMSC4 with the internal cushion helps to reduce vibration transferring from the trailer into your chassis. This can be paired with the Convert-A-Ball...

  • Shock Absorbers in Convert-A-Ball Cushioned Ball Mounts
    The Convert-A-Ball Cushioned Ball Mount, # AMSC4, has two shock absorbers, one in front of the pin hole and one behind the pin hole. This is true for all Convert-A-Ball cushioned ball mounts. Check out the diagram I attached.

  • 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 Draw-Tite...

  • 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...

  • Ball Mount And Brake Controller Recommendation for a 2010 Toyota Tundra
    The closest fixed ball mount we have to a 2 inch rise is the Ball Mount 2-3/4 inch Rise or 4 inch Drop, 6,000 lbs, item # 2753. 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. I would recommend the higher 2-3/4 inch ball mount to allow for a bit of rear end sag when a trailer is attached. We have several 2-5/16 inch balls, you will need to...

  • 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 etrailer hitch part # e98864 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.

  • 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.

  • 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 is...

    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 ball...

  • Recommended Ball Mount with 4" Drop for 2005 Ford F-150 Towing 12-Foot Utility Trailer
    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...

  • 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.

  • 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...

  • 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.
