Review from a similar Curt Drawbar in Trailer Hitch Ball Mount


I am an infrequent trailer user, but getting my daughter home from college was necessary in March. This drawbar fits my hitch and utility trailer well, did exactly what it is supposed to do, and was the last thing to be concerned about right then. I have a '11 Mini Countryman S with a Class II receiver from Mini Fini, (which cost twice as much as a Curt) where the hole is flush with the fake grille near the bottom of the bumper cover, so I needed the long bar to reach out past the bumper. The Curt receiver for that car hangs visible underneath the bumper (ugly), which also increases the lever arm on the receiver beam and would have needed an even taller rise. (Curt take note!) All just part of the kit to create an occasional 1 ton pickup out of my Mini, leaving the "bed" at home most of the time.

Review from a similar Curt Drawbar in Trailer Hitch Ball Mount


This drawbar was exactly what I needed with the 5" rise. I use it to tow my boat. My car is low to the ground so the rise was just what I needed. The drawbar is very durable as well. When I was out on my boat a hit and run was done on my trailer. The trailer was pushed into my car and both were moved about 3 feet forward. The drawbar didn't break in half. It was bent but it prevented any damage to the rear of my car because of the quality construction of the drawbar.

  • 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.

  • How Thick is the Ball Platform on Curt #45503
    The platform where a ball would install on the # C45503 is 1/2 inch. There can be slight variations due to the powder coat finish, but only slightly. The shank on the # C45503 is a completely solid 1 1/4 inch milled bar, but again, there can be very slight variations due to the powder coat.

  • 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,...

    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.

  • 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.

  • 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...

  • 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...

  • 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 # 118336, for a ball mount # C45503, 2 inch ball # A-82, and 1-7/8 inch...

  • 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...

    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...

  • 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.

  • Installation of Draw-Tite Class II # 36538 Receiver Hitch on 2014 Cadillac XTS
    The Draw-Tite Class II hitch, part # 36538 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...

  • Weight of Curt C12038 Class II Hitch for 2005 Subaru Forester
    The Curt Class II # C12038 hitch has a shipping weight of 31 lbs. Minus the shipping packaging, the hitch will weigh in at about 27 lbs. If you'll be towing with the hitch, you'll also need a wiring harness like # 118461, a ball mount like # C45503, a # PC2 hitch pin and either an # A-80 for a 1-7/8 inch trailer ball or # A-82 for a 2 inch ball.
