Towing Set Up for a 2021 Mazda 3 Hatchback


Hello, My car is 2021 mazda 3 hatchback with Aero kit. Based on this question, 555352 It seems like this is exactly same car as mine with Aero kit which has a different styles of rear bumper and spoiler than without aero kit model. If it is true, that means this trailer tow can fit my car no problem Addition to that, Im looking to tow a U-Haul motorcycle trailer with my bike which is weight at 189 kg / 417 lbs My question is will this trailer tow work with this Uhaul trailer and Please also suggest all the other necessary parts like trailer balls or anything else to me so I can buy all of them at once. Also does the price shown on your website is US dollar?

Yes, the Curt Trailer Hitch Receiver item # C98BR is a confirmed fit for the hatchback model of the 2021 Mazda 3. This hitch is custom fit and bolts directly to your Mazda with included hardware.

It has a maximum gross trailer weight of 2,000 lbs and a maximum tongue weight 200 lbs. This will be suitable for the 800 lbs uhaul trailer and your 417 lbs bike but you will want to check your owner's manual to ensure your Mazda 3 has the capacity to pull that much of a load.

For a wiring harness you will need a 4-flat connector. The motorcycle trailer you are pulling does not have electric brakes so this is the only wiring harness you will need. I recommend the Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector item # 118808. This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located in the rear cargo area.

Our prices are in US dollars

You will need a ball mount and 2" ball to tow your trailer. The Curt Towing Starter Kit for 1-1/4" Hitches - 2" Ball - 3/4" Rise - 3,500 lbs item # C45147 will take care of both of those needs in this one convenient kit.

You will also want to pick up the etrailer Trailer Hitch Receiver Lock for 1-1/4" Hitches - Flush - 2-1/8" Span - Chrome item # e98879. This will keep your ball mount from walking away.

Since you are wanting to pull such a heavy load with a small car I recommend adding an transmission cooler to your Mazda. The Derale Series 8000 Plate-Fin Transmission Cooler Kit w/Barb Inlets item # D13503 is custom fit and includes complete mounting kit, OEM spec hose, and stainless steel clamps for an easy installation. The radiator-style, plate-and-fin heat exchanger provides increased surface area so that fluids can spread out along the finned chambers to cool faster. In addition to the increased surface area, this cooler also features turbulator technology, whereby fluids are agitated continuously, not only to facilitate heat transfer, but also to prevent any undesirable drop in pressure.
