  • Trailer Hitch Receiver Confirmed To Fit The 2024 Buick Enclave
    Yes, the Curt Trailer Hitch Receiver # CU29FR will fit your 2024 Buick Enclave. This receiver is designed to fit behind the removable rear fascia panel providing a clean factory look which can be hidden when not needed. You can combine this with either the 4-Way # C56394 or 7-Way # C56393 depending on which connector you may need for the trailer you could tow. If you only intend to use this with hitch mounted accessories the 4-way will allow you to use Auxiliary Lights # C53201 in the...

  • Most Concealed Hitch for a 2023 Chevy Traverse
    The most concealed hitch for your 2023 Chevy Traverse is going to be the Curt Trailer Hitch item # CU29FR. This hitch is custom fit and bolts to your Chevy with included hardware. I really like the Curt item # CU29FR because it installs behind your rear bumper cover and can be completely hidden when you are not towing. This is a class III hitch with a 2" receiver. It has a 5,000 lbs towing capacity, and a 750 lbs maximum tongue weight. I have attached a couple of pictures below, along...

  • Does Mounting Bracket For Curt 4-Flat on 2020 Chevy Traverse Come with Holes Pre-Drilled
    Hi Dave, Yes, the Mounting Bracket 4-Pole Flat # 18144 does come with mounting holes pre-drilled so you can mount the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56394 on it for your 2020 Chevy Traverse. I believe that's what you were asking, but if you were asking about if the # e56YR hitch or harness has any holes, then no it does not.

  • Recommended 4-Way and 7-Way Connectors for a 2023 Chevy Traverse
    I have both a 4-way and 7-way connector that are custom fit for your 2023 Chevy Traverse. They are the 4-Way Curt T-Connector Vehicle Wiring Harness item # C56394 and the 7-Way Curt T-Connector Vehicle Wiring Harness item # C56393. These custom-fit T-connectors plug into your Traverse's wiring harness, which is located above the muffler on the driver's side. I have linked a couple of installation videos for both below. Neither one of them have a back up alarm. The only option to purchase...

  • Trailer Hitch And Wiring For 2018 Buick Enclave Essence
    Excellent question! Personally I recommend the Curt # CU29FR which is a direct fit for your 2018 Buick Enclave Essence. Not only is the Curt a super reliable and excellently built product but it is also conceals very nicely when not in use due to its recessed design; which, allows it to sit behind the rear fascia. Additionally, a fine choice for wiring would be the Curt T-Connector Vehicle Wiring Harness # C56394 which is a super easy, plug and play harness. If you are in need of a ball...

    If I were in your shoes I would be installing the etrailer hitch receiver on my 2023 Chevy Traverse and using the aluminum Flint Hill Goods cargo basket and pick up the anti-rattle lock for some security: - etrailer Trailer Hitch Receiver # e56YR - Flint Hill Goods 22" x 60" Cargo Carrier # FHG49ZR - etrailer Anti-Rattle lock # e99047 I like this combination because the hitch installs behind the bumper cover so you still get an OEM look when you aren't using the carrier, the carrier...

I really like the Draw-Tite hitch item # 76184 because it installs behind your rear bumper cover and can be completely hidden when you are not towing. This is a class III hitch with a 2" receiver.

  • Recommended Trailer Wiring Harness For A 2021 Chevy Traverse
    Hi Motty, 2021 Chevy Traverse's have a factory connector at the back to plug into so you can go with either a 4-pole # C56394 or 7-way # C56393 connector depending on your needs. Personally, I'd go with the 7-way and if you need to connect to a 4-pole trailer wire harness you can just use an adapter # PK12716. Having a 7-way will allow you to install a brake controller and tow trailers with brakes so it's just going to offer more versatility. To mount the 7-way connector I recommend...

  • Trailer Hitch and Wiring Recommendation for 2021 Buick Enclave
    For your 2021 Buick Enclave the trailer hitch I recommend is the Curt Class III part # CU29FR which can be hidden when not in use and also has great towing capacities. I attached an install video for you to check out. Then for 4-way trailer wiring you'd want the part # C56394.

  • Recommended Trailer Wiring For A 2020 Buick Enclave
    If you need the 4 pole connector on your trailer, I would recommend the Tekonsha T-One Connector # 118761 over the Curt # C56394. It provides more length for your installation, heavier duty wiring, with a more robust dust cap construction. The mounting bracket # 18144 for installing the connector as well as dielectric grease # 11755 to keep out corrosion and dirt would wrap up this package. If you instead have a 7 pole connector on your trailer, I recommend the Curt T-Connector # C56393...

This is a Class III receiver with a maximum gross trailer weight of 5,000 lbs and tongue weight of 500 lbs. I have attached a picture to show what this hitch looks like installed on a Traverse.

  • Trailer Hitch And Wiring Options On 2021 Chevrolet Traverse
    A hitch and trailer wiring can certainly be installed on a 2021 Chevrolet Traverse. The etrailer Trailer Hitch Receiver # e56YR would be a great choice; this is confirmed to fit all models of the 2021 Traverse. It has a max towing capacity of 5000lbs, and a max tongue weight of 750lbs. Be sure to comply with your vehicle's capacity so that you don't overload.

  • Recommended Hitch and Wiring Harness to Tow a Trailer w/ a 2023 Chevy Traverse
    I would be happy to help you set your 2023 Chevy Traverse up to tow a uhaul trailer. The first thing you will need is a hitch. I recommend the etrailer item # e56YR. This hitch is custom fit and bolts to your SUV with included hardware. The etrailer Hitch item # e56YR has a 2" receiver which will give you plenty of ability to pull a uhaul trailer and also provide you with the most options if you want to use a cargo carrier or bike rack.

  • Hidden Trailer Hitch Recommendation for 2021 Chevy Traverse
    For your 2021 Chevy Traverse the hitch I recommend is the mostly hidden Curt part # CU29FR which is only visible when you remove the rear bumper cover so it's totally hidden when not in use. I attached an install video for this for you to check out as well on a similar Traverse. To add a 4-way trailer wiring harness you'd only need the part # C56394 which installs very easily and you'd be set. Install video for this is attached as well.

  • Recommended Brake Controller For A 2018 Chevrolet Traverse
    When it comes to installing a brake controller in your 2018 Chevrolet Traverse with factory tow package I recommend The Curt Echo Wireless Trailer Brake Controller - 1 to 2 Axles - Proportional # C51180. This controller automatically adjusts trailer's braking based on deceleration of tow vehicle. The controller has a fast, plug and play installation with no tools required. The controller has a user-friendly, app that lets you connect, monitor, and control all of your trailer's braking...

  • Recommended Wiring Harness for a 2020 Chevy Traverse
    The Curt T-Connector Vehicle Wiring Harness item # C56394 for a 4-way or item # C56393 for a 7-way is what I recommend for your 2020 Chevy Traverse. These are custom fit and quite a bit easier to install when you're putting the hitch on. Just like the Draw-Tite Hitch item # 76184 they require the rear bumper cover to be removed. If you ever plan on towing a heavy trailer like a camper you will want the 7-way Curt Wiring Harness item # C56393 because it can control trailer brakes. The item...

    The Curt Trailer Hitch Receiver part # C13380 which is a fit for a 2019 Chevrolet Traverse Premier and does not require removal of the rear bumper will still allow for use of the hands free life gate feature. In order to use the hands free life gate feature you simply need to place your foot on either side of the receiver tube opening. There are some vehicle/hitch combos that pose more issues for the hands free life gate feature than others but this is not one of them and will still work...

  • Towing Capacity for 2018 Chevy Traverse AWD
    5,000 lbs appears to be the weight capacity of the 2018 Chevy Traverse if it has the 3.6 liter V6 engine and 1,500 lbs if the engine is the 2.0 4 cylinder. Those figures are the fully loaded capacity that your truck can tow. If you are going to be at the capacity of vehicle a weight distribution system would be recommended. For that I recommend the Strait Line part # RP66082 which has a tongue weight range of 200-600 lbs and features the best sway control designed to fight sway before...

    Yes, the Curt Trailer Hitch Receiver # CU29FR does fit your 2022 Chevrolet Traverse. This hitch has a maximum towing capacity 5,000-lbs and a maximum tongue weight capacity of 750-lbs. I recommend that you check your owners manual, and refer to your vehicles maximum towing capacity, and compare that number to the hitch and use the lowest rating between the two. If you want a complete towing setup, you'll also need wiring # C56394 and a ball mount # C45030.

  • Curt vs. etrailer Trailer Hitch For 2024 Buick Enclave
    Just a single difference exists between the Curt and etrailer trailer hitches for your 2024 Buick Enclave, which is the finish - the etrailer hitch has a matte black finish, while the Curt hitch has a glossy black finish. The hitches that fit your '24 Enclave are the following part numbers: - Curt Trailer Hitch Receiver # CU29FR - etrailer Trailer Hitch Receiver # e56YR The matte black finish does generally hide those inevitable small scuffs a bit better than the glossy finish, though...
