Ordered this for a 2024 Silverado 2500HD even though it wasnt certain that it would be compatible. Once i figured the connections out the actual install took maybe 15 minutes! Ill add i coated all the connection pins with dielectric grease before reconnection. Worked perfectly.

The wiring harness was super easy to install. The instructions are easy to understand. I highly recommend this to anyone wanting to add a 7-Pole trailer connection to the inside of their bed.

Great Product!! Dealer wanted $200 to $300....Watched the accompanying video, and Installation was pretty straight forward on My 2022 GMC 2500HD. The only pain was getting at the Factory connection clip on the original plug... I chock that up to being my own fault for not dropping the spare tire down for ease of access...



by:

I liked this kit. It looks and feels like high quality. Installation was easy and it took very little time to get clean results. Etrailer was great to work with. I talked with Kim on the phone due to some questions that I had after I received my order. The call was professional and helpful. I would order from etrailer again.

I was mad when I saw this, paid $200 to have installed in my previous truck’s bed. When I watched the video and saw it was plug and play I ordered and installed my self in less than 30 minutes. Shipping took a week but I won’t need it until the 3rd week of August when I head out with the fifth wheel. Product came as advertised with every thing needed to install. It looks factory (see pic). I am very happy with how it came out and the installation video was excellent.

Exactly what needed and ordered. Fast shipping. Thank you!

Arrived the next day and I only selected basic shipping. This is the only company that seems to have what they sell in stock and ships quickly. Also if you have a problem they bend over backwards to make it right.

Excellent product.

It was simple to install and worked great for a 12k mile summer trip.

This was probably one of the fastest items to install on everything I have added to my 21 GMC Sierra 2500HD, Denali Duramax. The right angle plugs make it simply slip in, plug and play.

Good instructions and simple to install.



by:

Was perfect for what I needed.



by:
2021 GMC Sierra 2500

I love the setup but I have a concern that the connection in the bed once installed has a slight right angle into a sharp bed seam. It is at the spot right at the connector with no cable armor. I am concerned this will wear and cause a short down the line.

I would need to see your set up that you have under the vehicle. Can you please send me a picture of what you are concerned about?



by:
2023 GMC Sierra 3500

Worked with Neil on a GMC 2024. U known if adaptable with new GMC. Built my confidence as we spoke. Anyway, it did fit and works great with camper and boat. Made my own face plate to use the dummy hole on the driver's side. Extended my RV cord to fit. No holes drilled in bed. Would of worked better with the GMC factory fit plug but not the case. Excellent. It does work with the 2024 GMC.

Just what I was needing for my 2022 Silverado 3500 HD. Worked perfect. Great accompanying videos to help with installation

  • Can I Install a Gooseneck Hitch in a 2023 GMC Sierra 1500?
    Yes, you can! Actually the B&W Turnoverball Underbed Gooseneck Hitch item # BWGNRK1019 fits all three bed lengths and the diesel models of the 2023 GMC Sierra 1500. This system includes custom fit brackets that bolt into existing holes in your Sierra's frame. This underbed system allows you to store the 2-5/16" hitch ball upside down and inside your bed when you are not using it. This gives you full access to your bed when you're not towing. The locking handle is easily accessible inside...

  • B&W Gooseneck Hitch Fit for a 2022 Chevy Silverado 3500
    The correct B&W Turnoverball Gooseneck Hitch for your 2022 Chevy Silverado 3500 is the part # BWGNRK1020. This fits both the short and long bed pickups, is made here in the USA, and is backed by a limited lifetime warranty. We've had the opportunity to install this on a 2022 Chevy 3500 which I'm attaching the video for you to check out. I also recommend picking up the Curt Wiring # C53CR which tees into the back of your 7-Way connector and gives you a 7-Way in your truck bed so it's easier...

  • Recommended 5th Wheel Rails for a 2024 Chevy Silverado 1500
    To add a set of 5th wheel rails to your 2024 Chevy Silverado 1500, I recommend the Curt Custom 5th Wheel Installation Kit item # C65KR. This set of rails is industry standard which means they will work with most 5th wheel hitches on the market. They fit both the 6-1/2' and 8' bed lengths. To make towing with a 5th wheel easier, I recommend adding the Curt 5th Wheel/Gooseneck Custom Wiring Harness item # C53CR. This harness puts a 7-way connector in the bed of your Sierra and allows you...

  • Difference Between Curt 5th Wheel Base Rail Kits For 2021 GMC Sierra 1500
    That's a good question, and the only difference between the two base rail kits that fit your 2021 GMC Sierra 1500 (6-1/2 foot and 8 foot bed) is the finish. One is a glossy black finish and the other is a carbide black, which essentially means it just doesn't have quite as much shine to it. Otherwise, they are exactly the same, with the same parts and no-drill install in the frame rails of your truck: - Gloss Black Finish: Curt Semi-Custom Fifth Wheel Installation Kit for Chevy/GMC Truck...

  • Best 5th Wheel Hitch For 2024 Chevy Silverado 2500 Short Bed
    I definitely recommend going with a sliding hitch for your short bed 2024 Chevy Silverado 2500 to ensure your trailer doesn't crash into the cab of your truck. This is especially true since you mentioned the switchback roads and tight turns. With that in mind, the best 5th wheel hitch is going to be one that does not require you to get in and out of your truck to slide the hitch, so it will be much more convenient for you. The hitch is an autoslide, from Demco; for the hitch and 5th wheel...

  • 5th Wheel Base Rails & Custom Brackets For 2024 Chevy Silverado 2500HD
    Hi there Brad; good questions and let's start with the 5th wheel base rails, as you will need new ones to go with a custom, no-drill install kit for your 2024 Chevy Silverado 2500. The reason is you can't mix and match base rails and brackets, and I believe by "Pro" you are referring to old Pro Series rails, which there aren't brackets for. So for new rails and brackets the best option is the following: - B&W Custom Installation Kit w/ Base Rails # BWRVK2505 I like the B&W # BWRVK2505...

    So the answer to your question is yes, for your 2022 Chevy Silverado 2500 with the 6 foot 9 inch standard bed, you will need the B&W Companion Slider # BWRVK3400-5W instead of the fixed B&W Companion # BWRVK3500-5W to safely execute a sharp turn without hitting the cab.

  • Troubleshooting Left Hand Turn Signal Not Working On Curt 5TH Wheel Wiring Harness # C53CR
    I would start by disconnecting the Curt 5th Wheel/Gooseneck Custom Wiring Harness # C53CR so you will be able to verify the issue is with this and not either the wiring or a fuse on your truck. Since you mentioned that both connectors are not working I fear it may be a part of the trucks wiring or a damaged connector going into the trucks wiring. Once you have verified this please let me know what you find. Do note the harness has a 1-year warranty through Curt.
