Video Transcript for Curt Ball Mounts - Fixed Ball Mount - C45503 Review

Speaker 1: Today, we're taking a look at the Curt Class 2 Drawbar. This is a study steel construction. It's got the solid back here on the shank. It's corrosion resistant, meaning that you don't have to worry about rust or corrosion with this unit. It has a black gloss powder coated finish, so it's designed to look good and last for a really long time, and it goes through a high quality manufacturing process. It's CNC machined for strong consistent cuts and welds, and it goes through a seven stage washing method to deliver a smooth, nice, clean surface.

Now, once you have this installed in your inch and a quarter by inch and a quarter trailer hitch, it does offer where it can be used in both the drop and rise positions to help ensure level towing.Your hitch pin and clips are secured inside your receiver tube where a hitch lock is not included. If you're in need of one, you can find them at The pinholes on this unit will accept your standard half inch diameter pin. The product, again, it's made durable steel. It's made in the USA.

It is designed for inch and a quarter by inch and a quarter trailer inch receivers, class two only. The gross towing weight capacity is 3,500 pounds, maximum tongue weight capacity is 350 pounds. The drawbar width, it's measuring this point here, is two inches. Drawbar thickness, that measures 5/8 of an inch. The ball hole diameter is 3/4 of an inch.

The length measurement from the center of the hitch pinhole to the center of the hitch ball hole is 7-13/16 inches.That's going to do it for today's look at the Curt Class 2 Drawbar.

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

  • Trailer Hitch and Wiring Recommendation for 2004 Subaru Forester
  • Best option would be the trailer hitch part # C12038 which is a fit for your 2004 Subaru Forester, but you'd need to verify that your vehicle has the capacity for the pontoon boat. The hitch by itself has a 3,500 lbs capacity. For trailer wiring you'd need the part # C55370 which is a confirmed fit. For a ball mount part # C45503 and then hitch balls # A-82 for a 2 inch ball or part # A-80 for 1-7/8 inch ball.

  • Parts Needed to Tow a Trailer with a 2005 Mitsubishi Outlander
  • The trailer hitch receiver with the highest capacity for your 2005 Mitsubishi Outlander is the Curt Class II # C12293. It bolts onto the Outlander's frame with no drilling and includes all the necessary hardware. Then to power the trailer's lights use # 118306 for a wiring harness. It plugs into the Outlander's wiring behind the side panels in the rear cargo area. You have to remove the plastic vent covers to access the connection points. See the picture I attached for the locations. You'll...

  • Installation of Draw-Tite Class II # 36762 Receiver Hitch on 2014 Cadillac XTS
  • The Draw-Tite Class II hitch, part # 36762 does indeed make use of existing holes, but the hole used for the forward-most attachment point will need to be enlarged with a 1/2 inch drill bit. The exhaust does not need to be dropped, but one of the exhaust hanger bolts is replaced with a longer bolt. If you will be towing with your XTS, I would recommend a ball mount like # C45503. You will also need a hitch ball like # 19256 for a 1-7/8 inch ball or # 19258 for a 2 inch ball. To complete...

  • What is Included with Curt Trailer Hitch 12038 for a 2008 Subaru Forester
  • For Curt trailer hitch # C12038 you will get the trailer hitch itself and the hardware needed to install it. The other parts you need depend on what you're going to use the htich for. If you're going to be carrying a cargo carrier or bike rack you also need a support strap # 18050 per Curt's warranty. If you plan on towing a trailer you need to add ball mount # C45503 along with the properly sized ball and the wiring. Those items are not included with the hitch. For a 1-7/8 inch...

  • Recommended Trailer Hitch for a 2008 Acura RDX
  • For your 2008 Acura RDX, the two 1-1/4 hitch receivers you mentioned, # C12004 and # 36427, have the same tongue weight and towing weight ratings. They both have a similar design and mount. One distinguishable difference is that the Curt hitch is made in the USA and the Draw-Tite hitch is made in Mexico. Also, Curt requires the use of a stabilization strap, like part # 18050, when carrying any non-trailer loads such as a bike rack or cargo carrier. If you choose to tow a trailer,...

  • What is the Correct Ball Mount for Curt Trailer Hitch C11227 on a 1994 Toyota Celica ST
  • This is actually a lot easier to determine than you might think. With any Class I or II trailer hitch you will need to use the ball mount recommended in the hitch instructions. The use of any other ball mount can result in voiding the hitch warranty. The reason is that on Class I and II hitches the ball mount recommended has been tested for and approved for use as the best option for those hitch and vehicle combinations. For trailer hitch # C11227 the recommended ball mount is # C45503....

  • Can a 513 Pound Motorcycle Be Carried on a Trailer Hitch Mount Carrier on a 2001 Subaru Forester
  • You are correct. The highest tongue weight capacity of a trailer hitch for the 2001 Subaru Forester is 350 pounds for hitch # C12038. The combined weight of the carrier and the bike would have to be under 350 pounds. The best option and the safest is to use a small trailer or one specifically designed for a motorcycle. You will also need a ball, ball mount, and wiring. The recommended ball mount is # C45503. You also need pin and clip # F-4. For a 1-7/8 inch diameter ball use # A-80...

  • How Long is the Curt Class II Ball Mount D-55003/45503
  • Curt ball mount # C45503 measures approximately 7-3/4 to 7-13/16 inches from the center of the hitch pin hole to the center of the ball hole. From the center of the hitch pin hole to the nearest part of the welded-on ball platform it is approximately 2-1/2 inches. I have included a picture that should help as well.

  • Trailer Hitch for Towing Small Trailer with 1991 Toyota Camry
  • We have a trailer hitch fit for your 1991 Toyota Camry, the Curt hitch part # C11223. But it has a tongue weight capacity of 200 lbs so it would not be able to carry a wheelchair that weighs 300 lbs unless you went with a small trailer instead of a carrier. We do have small utility trailers like the part # K2MMT4X6 which would work. For a ball mount you'd need the part # C45503, for a 2 inch hitch ball part # A-82, and then for trailer wiring part # C59236.

  • Hitch Recommendation for a 4 Bike Hitch Mounted Rack on a 2006 Mitsubishi Outlander
  • I can help you figure out which hitch and bike rack you will need to support your 4-bike capacity on your 2006 Mitsubishi Outlander. You are correct, a Class I hitch is only capable of supporting the weight of 2 bikes, even if the bike rack is a 4-bike because your limited by your lowest rated capacity which would be your hitch. I would recommend going with the Class II Curt # C12293 over the Class I Hidden Hitch # 60824. The Curt Class II will give you a maximum of 300lbs tongue...

  • Recommended Hitch Receiver For 2006 Mitsubishi Outlander To Tow A UTV
  • For your 2006 Mitsubishi Outlander, I recommend the Curt Class II Receiver Hitch, # C12293. This hitch receiver has a 3500 lb towing weight and a 300 lb tongue weight which is the highest tongue weight available for your vehicle. The tongue weight is the amount of weight that the trailer coupler puts on the ball of your hitch. Typically this is 10-15% of the total towing weight of the trailer. I've attached an article that outlines how to determine trailer tongue weight. This hitch...

  • Hitch Recommendation for Transporting Dirt Bike with a 1997 Acura TL
  • The only hitches available for your 1997 Acura TL are Class I hitches with lower capacities. There are no motorcycle carriers that we offer that will fit a Class I 1-1/4 inch hitch. Your best option for using your TL as a tow vehicle is going to be to find a lightweight trailer for transporting the dirt bike. The hitch part # C11155 would be the correct hitch to use. For trailer wiring you would then want the part # C55366, for a ball mount # C45503, 2 inch ball # A-82, and 1-7/8 inch...

  • Will Installation of Trailer Hitch Receiver on 2008 Subaru Forester Require Drilling
  • We have two trailer hitch receivers for the 2008 Subaru Forester. The Curt # C12038 and Draw-Tite # 36311 and they both install without any drilling. I've linked install videos for both of them for you. If you're going to be towing a trailer with your Subaru use # 118461 for wiring. This harness installs by plugging into a connector that is located either behind the driver's side tail light or in the spare tire compartment. Once installed you'll have a fully functioning 4-way trailer...

It will be a little more confining but it can and has been done. If you don't want to do the work yourself, you can have any local mechanic you trust do the install for you.

  • Trailer Hitch for a 2007 Subaru Forester to Carry a Motorcycle
  • The only trailer hitch available for your 2007 Subaru Forester are Class II hitches with 1-1/4 inch receivers. But the Curt option, # C12038, has a high enough tongue weight capacity at 350 pounds. You would just need a carrier that fits a Class II hitch. And you will also want to check the vehicle owners manual for the tongue weight capacity of the vehicle. Whatever is lower, the hitch or the vehicle, is the capacity you need to go by. If you can tell me the size of the motorcycle you...

  • Trailer Hitch and Wiring for a 1992 Mercedes 400E
  • There is a special circumstance when using a Class I trailer hitch for towing. Basically you will have to use the ball mount specified by the hitch manufacturer or it can void the warranty. This is to ensure that the wrong ball mount is not used (which could be too much stress on a Class I hitch). Trailer hitch C11085 does not fit your 1992 Mercedes 400E. The hitch you need is # C11816. The recommended ball mount for this hitch is # C45503. For a compatible 1-7/8 inch ball use # 19256...

  • Hitch Pin Recommendation for a Curt Ball Mount C45503
  • I checked your order notes and it looks like you ordered the Curt Ball Mount part # C45503 and the hitch ball part # A-82. For a standard hitch pin and clip you would want the part # F-4 or for one that would lock and give you a bit more security you would want the locking hitch pin part # RH2-XL which is designed for 1-1/4 inch hitches. I attached a review video for this lock for you to check out as well.
