Video Transcript for Curt Ball Mounts - Fixed Ball Mount - D320 Review

Today we'll be reviewing part # D320, this is a Curt Ball Mount with Sway Control Bracket. It's going to offer a 3/4 inch rise or a 2 inch drop. It does have the built in bracket here on the right hand side for easy installation of the Sway Control Kit which is sold separately. This mount is designed to fit a 2x2 inch trailer hitch receiver, Wench is in the hitch ball, you want to make sure that the shank of the hitch ball does not exceed the ball hole diameter. Measuring this hole down here. With this mount, we have a 1 inch diameter, so that means that this ball mounts' going to require a hitch ball with a 1 inch shank in diameter, not in length. The diameter of the sway bracket here is going to measure 5/8 inch. The bracket itself is going to measure about 2 inches in width by about 4 1/2 inches from the end to the beginning of the weld.

This is a really simple installation, simply just take the shank of the mount and slide it into the receiver tube of the hitch, line up the pinholes and install a hitch pin and clip or a hitch pin and lock. Those items are sold separately and you can refer to the ball mounts' product page in the related items to view those products or go to our website and type in part # PC3, and that will refer you to this 5/8 inch pin that comes with the clip. With the mount in this position, this is the drop position, if we measure from the inside top edge of the receiver tube to the top of the ball platform, it's going to give us 2 inches, so that's the amount of drop that this mount provides. Measuring from the center of the hitch pin hole to the center of the ball hole, we have a measurement, about 7 1/2 inches. This mount is available to use in the rise position as well. Just take it out and flip it over, line up the pin holes.

In this position, it's going to give us a rise of 3/4 inch. The distance from the center of the hitch pin hole to the beginning of the upright curve here, it's going to measure about 4 1/2 inches. You want to make sure you have the appropriate amount of clearance at the rear of your vehicle so that the mount doesn't interfere with the outermost point of your vehicle. If we measure from the center of the hitch pin hole to the rear of the mount, it's going to give us a measurement of about 2 1/2 inches. This does have a hollow shank on it, and the ball mount itself has a gross trailer weight of 7,500 pounds, with a maximum tongue weight capacity of 750 pounds. That's going to complete today's review of part # D320, this is a Curt Ball Mount with Sway Control Bracket. .

Item was as described and shipped very fast. I have not towed with it yet but see no problem. The shank (insert) part seemed slightly short to me. It was shorter that others I have. My trailer has an electric lift and I was concerned it might not clear the lift gate on the Jeep if it was too close. Worked out perfect though. Just something to thing about next time. 332108

by:

I cannot use this ball mount because the shaft is too short that goes into hitch receiver on my one ton Dodge truck. It does not allow enough room between truck back bumper and ball to allow any trailer tongue to be put on ball. 104820

Ask the Experts about this Curt Ball Mounts
Do you have a question about this Ball Mount?


  • Effect of Using Extra-Long Ball Mount for Towing
  • Use of an extra-long ball mount like # 80232 will not reduce a hitch's towing weight capacity the way that use of a separate extender/adapter will. Extenders like # C45791 and # D-192 actually do reduce the hitch towing capacity by 50-percent. Weight distribution hitch systems such as # C17501 should not be used with any type of hitch extender or adapter. A friction sway control unit like # 83660 can be used with an extra-long ball mount like # 80232 by adding a sway control bracket...

  • Sway Control Unit Recommendation for [email protected] Tear Camper Trailer
  • The Pro Series friction sway control unit part # 83660 that you referenced would be what I would go with if I were you. It is essentially the same thing as the other units and is at a much better price. Your trailer is pretty lightweight, but if you are getting any sway when semi trucks pass you or in strong winds this unit will help greatly. I attached an install video for more info for you to check out as well. With this you'll need a ball mount with a mounting tab for the sway...

  • Adjustable Ball Mount With Sway Control Tab
  • You can pick up a ball mount like the Curt # D320 with a sway control tab that offers 4 inches of drop right here on this page! The Draw-Tite # 7390 is adjustable between 3-3/4" of rise and 5-1/4" of drop and has a 6,000 lb towing capacity and 600 lb tongue weight capacity. Your other option is to use a ball mount with a 4" drop and 7,500 lb capacity such as the Draw-Tite # 2753 with Reese Sway-Control Bracket # RP26003.

  • Ball Mount Options that Have Sway Control Ball Mounting Tab
  • Some draw bars will have the sway bar ball attachment mounted to the side of the ball mount platform like the Curt Ball Mount part # D320. Other options include using an adapter like part # RP26003 which fits on top of the platform between it and the hitch ball. Or you can have the tab welded to the side of the platform with part # 3442. We also have an adjustable ball mount part # 7390 which allows for various drop/rise settings and has the platform for the sway control ball. With...

  • Are Additional Parts Needed to Install a CURT Friction Sway Control Arm
  • You will need a platform to attach the ball to the vehicle side for the CURT Friction Style Sway Control System, # 17200. It does come with a weld-on platform but you can also use Sway-Control Bracket, # RP26003, for 2 inch ball mounts or # RP26005, for 1-1/4 inch ball mounts. To use the weld-on platform that comes with it, you would need to weld it to the side of the ball platform on a ball mount.

  • Availability of 4-Inch Drop Ball Mount with Sway Control Bracket Like # D320
  • We do not offer a ball mount like # D320 but with a 4-inch drop, but you can choose the ball mount you need and then simply have the sway control bracket # 3442 welded on. For a 2-inch ball mount with a 4-inch drop and 7500-lb rating we offer Draw-Tite # 2753.

  • Sway Control Bracket Recommendation for a Left Hand Sway Bar
  • You can use the Curt Ball Mount with Sway Control Bracket, # D320, in the rise position to have the sway control bracket on the left side, but you will want to remember that doing this will raise the height of your trailer tongue by almost 3 inches. This can create additional sway issues even with a sway control bar installed. Another option that you can look into is using a weld on sway control tab like part # 3442. This tab can be welded to the side of your current ball mount to provide...

  • Adding a Mounting Plate for a Second Friction Sway Control Ball On a Ball Mount
  • You will need to use the weld-on friction sway control tab # C45822 or # 3442. It will get welded to the side of the ball mount. Welding should be performed by a qualified professional welder. Once welded on it will look like ball mount # D320 except the tab will be welded to the other side (since the plate you are using is occupying the passenger side of the ball mount).

  • Friction Sway Control Mounting Tabs for 2-Inch Ball Mounts
  • We do offer a 2-inch ball mount that has a friction anti-sway mounting tab already welded in place, Curt # D320, but this ball mount offers 2-inches of drop, not 4-inches. We do offer a 2-inch no-welding Sway-Control Bracket # RP26003 that fits on your ball mount in addition to the simple weld-on tabs # C45822 and # 3442.

  • Can Pro Series Friction Sway Control Kit # 83660 Be Installed on Driver's Side of Trailer
  • Thank you for your recent purchases. The Pro Series Friction Sway Control Kit # 83660 can be installed on the driver's side of your trailer since its internal friction arm can be removed and reinserted upside down, however the Sway Control Tab # RP26005 cannot be inverted to the bottom side of your ball mount. Instead you'll need to use part # 3442 which is a weld-on part that can be attached to the left side of your ball mount. Part # D320 shows an example of how such a combination...

I've attached a photo including some other measurements I took on this bracket for you. An easier solution to accommodate 2 friction sway control bars is to use 2 weld-on tabs # 3442 with your ball mount. The Curt Ball Mount with Sway Control Bracket # D320 has one sway control bracket already welded on to the ball mount. This ball mount offers 3/4 inches of...

  • Can Volkswagen Touareg Use Weight Distribution When Towing
  • You will need to check your owners manual to see what the trailer towing capacity is for your Touareg. Many times the construction of a vehicle will restrict the amount of weight the vehicle can tow. I looked at a 2010 Touareg and the trailer hitch we have that is designed for the 2010 is the Curt Trailer Hitch, part # 13220. This is a Class lll hitch and it has a 2 inch receiver opening. A technical note states that you cannot use weight distribution with this hitch. You will want...

  • Is There A Torque Spec For Trailer Sway Control Hitch Ball
  • I called my contact at Curt and asked about the torque needed for the ball that the sway control is attached to on the trailer hitch. They told me that there has never been a torque listed but if you would torque it to about 150 ft-lbs it will have no problems. There is no torque value in the installation instructions. You want to periodically check all of the towing components to make sure they are all secure and ready to use.

  • Can a Friction Sway Control Bar be Used with a 3-Ball Ball Mount
  • You will not be able to use a friction sway bar such as # 83660 with a tri-ball ball mount. There would be no place to attach the sway bar to the vehicle side and you would not be able to use a bracket or weld-on tab for the small ball the sway bar needs. A ball mount such as # D320 would be what you need. I have linked a video review of it for you.

  • Weight Distribution Compatibility with a 2005 Nissan Murano Class III Trailer Hitch
  • If your 2005 Nissan Murano came with a factory installed Class III trailer hitch, then your owners manual should tell you if a weight distribution system can be used or not. I can tell you that a weight distribution system cannot be used with any of the Class III trailer hitches that we offer for your vehicle. Your travel trailer is fairly light, but if your vehicle sags a lot when towing your trailer, then you could look into the Firestone Coil-Rite Air Helper Springs, # F4118. These...

  • How Does a Second Friction Sway Control Unit Get Installed on a Trailer
  • You are correct, adding a second sway control bar, like the Curt Friction Style Sway Control, # 17200, is recommended for trailers over 26 feet long. You will need to use the weld-on friction sway control tab # C45822 or # 3442. It will get welded to the side of the ball mount. Welding should be performed by a qualified professional welder. Once welded on it will look like ball mount # D320 except the tab will be welded to the other side (since the plate you are using is occupying...

  • How to Mount Sway Control Ball on Right Side of Ball Mount Used in Rise Position
  • I do have a solution for you. Simply use a ball mount with the same rise, like part # 2923 along with a sway control tab, part # RP26003. The tab is placed on top of the ball mount once it is situated in the rise position, and is installed so that it is sandwiched between the trailer ball and the ball mount. We do not carry a ball mount that would have the tab on the right side when used in the rise position.

The Curt sway control # 17200 you referenced will work great with towing your 1,400 pound Scamp. It will also include the Curt hitch ball # C40093.
