Knowledgeable and helpful. Item was as described and just what I wanted. Quick shipping and kept me informed with tracking.

I called and staff was knowledgeable about the part I needed. It arrived in a timely fashion less than a week. Highly recommend etrailer
by:
Everything was included in the box, even self-tapping screws and cable ties. I watched their Utube video and installed it in about 30 minutes. Works great!
by:
The kit was perfect for my application just as it was listed. The installation instructions were easy to follow.
by:
Everything fit great and the harness plugged right in.
by:
This was super easy to install, truly plug and play. It appears to be identical to a factory oem harness and connector.
by:
Not oem quality requires to drill holes in bed of Chevy instead of using oem style mount plate
by:
Very easy to install. But it would be a whole lot easier if they made it shorter. You have a lot of extra wiring harness you have to wrap up tie up out of the way.
by:

Plug and play what more can you say. Easy to install fits perfect like stock.
by:
2026 Chevrolet Silverado 2500
Item came defective. Wrong cable included and plugs were cut off the ends plus it didn't have the splitter end at all. Contacted E-Trailer and was told they'd have to wait for it to get back to them before a 2 week wait for refund. Very frustrated and utterly disappointed in such poor customer support. Will be unlikely to shop here again.

Overall it was an easy install. Still need to connect to trailer and test.
by:
2026 GMC Sierra 2500
Product fit perfect . The only two negatives are it showed up later than it said when the order was placed. And the box was beat up and the hardware was loose in the box. The hardware started out in a large bag but it tore open and spread everywhere. Lucky only one nut had escaped the box. But even that was a hassle to locally source a shouldered nut of that size.

Great price, same as factory equipment, comes with adaptor plate to match factory filler plate. Installed on my 2024 Silverado 2500

This works great! Easy to install. I would ask that a small tube of dielectric grease be included.
Thank you for another GREAT purchase from Etrailer.com
by:
2022 Chevrolet Silverado 2500
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.
by:
It worked great. I didn’t have to cut or splice anything. Just plug and play. Love it
by:
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.
by:
2022 Chevrolet Silverado 2500
I ordered and paid for expedited shipping. Although I have finally received my product it is 2 weeks or longer past the time I needed it. I realize that shipping is not always your issue but I started receiving “how was your product” and “rate your product” literally weeks before I received it. I had a time frame that I would have time to do this job and that time frame has come and went a long time ago. If you guys can’t handle the logistics, use [online vendor] to market your goods.
by:
Very easy straight forward install looks factory high quality. Highly recommend.

2024 Chevrolet Silverado 2500
It works perfect and easy to install
by:
2022 Chevrolet Silverado 2500
It only took 20 minutes to install.
by:
Product was a great factory fit for my 2022 GMC 2500hd. Install was straightforward. A little dielectric grease on the connections and zip ties to hold up the extra length and we were all set. The toughest part was trying to get the spare tire down to get more working room as the key fitting for the tire was corroded and had to use spray to loosen it up!

Awesome, works like a dream

Plug n Play so easy to install.

  • Best 5th Wheel Hitch For 2024 Chevy 2500 4dr Crew Cab With 6-3/4' Bed
    Hey Justin, I can definitely help with this. I do recommend going with a sliding 5th wheel hitch since your truck is not a long bed. The slider helps with clearance on tight turns. What I recommend is the B&W Companion OEM 5th Wheel Hitch w/ Slider # BWRVK3775. This is made specifically for the factory pucks in your Chevy, so installation is simple. The slider allows for 12" of front-to-back travel. Overall the B&W hitches are super solid. The head is fully articulating so you get smooth...

This set of rails are industry standard and are definitely compatible with Andersen Ultimate 5th Wheel Hitches like item # AM3200. The brackets included with the B&W item # BWRVK2505 are custom fit and install in pre-existing holes in your Silverado's frame. They fit the both the 6-3/4' and 8' bed lengths and include all...

  • Parts Needed to Use Andersen Aluminum Ultimate in 2025 Silverado 2500 Without Prep Package
    Hey Adam! All you need to use the Andersen Aluminum Ultimate 5th Wheel Connection 2 Gooseneck # 3220 is a gooseneck hitch. The best option is going to be the B&W Turnoverball # BWGNRK1020. The Turnoverball allows the ball to be stored upside down so you have full bed access when not in use. It also gives you the option to use the B&W Companion # BWRVK3500-5W if you ever decide you want to use a traditional 5th wheel hitch. Then for a 7-way in your bed you can use the # C53CR which plugs...

    Hey Brian. To install a set of 5th wheel rails on your 2024 GMC Sierra 3500 long bed dually, I recommend the Curt Custom Fifth Wheel Installation Kit item # C16429-204.

  • What is Needed to Install Demco 6077 5th Wheel Hitch in 2020 GMC Sierra 2500
    Hey Rob, I can help you get what you need for your 2020 GMC Sierra 2500 to install the Demco # DM6077 hitch. I assume when you say "no mounting" that you don't have the side plates for the hitch, or the base rails for your truck. So with that in mind, here's what you'll need: - Replacement Side Plates for Demco Autoslide 5th Wheel Trailer Hitches # DM6003 - Curt Custom Fifth Wheel Installation Kit for Chevy/GMC Truck # C16429-204 The side plates will attach to the # DM6077, and the...

For your 2022 GMC Sierra 3500 you will need the B&W Turnoverball Underbed Gooseneck Trailer Hitch item # BWGNRK1020. I have linked an installation video below to help you get it set up.

If you have the prep package you can use the B&W Companion OEM 5th Wheel Hitch w/ Slider # BWRVK3775. If you do not have the prep package I have two options.

  • Do You Have a In-Bed 7-Way Connector w/ Camera Inputs?
    Hey Rex! Sorry, we do not carry anything like that. What you're describing sounds like the Trailer Tow Harness Connector 13530416, which is a GM OEM part. I have never seen it come with the in-bed 7-way connector like the Curt item # C53CR, you referenced. What you would need to do is source that connector from a vendor who carries OEM parts and then pair it up with the Curt item # C53CR. They both use the USCAR 7-way socket which is that circular connector. It's been standard amongst...

This will give you the proper turning clearance so you don't have to worry about hitting your truck when you're making tight turns. There's two different configurations of this hitch depending on whether or not your 2025 Chevy Silverado 2500 came with the factory puck system or not. I have listed them...
