Best 2021 GMC Sierra 3500 Gooseneck and Fifth Wheel Adapters

Hitch arrived on time. Packaging was a little beat up but everything inside was fine. I did the installation myself and had no issues. The install video etrailer made was a big help and good reference. I'd absolutely recommend getting this hitch if you have a gooseneck hitch and are looking for a 5th wheel hitch that can be used with it.

i've hauled gooseneck horse trailers for years with the b&w turnover ball. when i purchased my first fifth wheeler I was in the market for a 5th wheeler hitch. this companion seemed to be a no brainer. happy to report design, function and ease of use exceeded my expectations. excellent product and customer experience.

Fit like a glove. Dropped right in and I installed the 5th wheel hitch in no time. Heavy and well built.

Great product! Ive pulled a 42' to Hell and back not one problem. It is heavy, but it's very solid. My fifth wheel hitch fit straight in. Way cheaper than having to put rails in if you have a factory ball hitch in the bed. Its It's also nice that it's removable so you can haul furniture, or things that can't sit crooked ect. Great product, should last forever. Definitely would recommend

This product fits my fifth wheel hitch well and fits in the truck hitch as well. Have not pulled with it yet as winter storms are here. I expect it to work well. Expensive for as simple as it is. Hoping it is built well. Nice That I was able to get a used one at a reduced rate. Missing the pads so we’ll see what kind of a difference that makes. Very happy with etrailer as a distributor. They make the purchase easy and quick free delivery. They Always follow up on my satisfaction with my purchase’s.

only shipped half of hitch said they would over night rest never got it had to purchase different brand else where as we were leaving on trip

It looks and feels great. Nice to be able to use my truck pulling a fifth wheel.

Heavy and doesn't fit flat on my truck bed, had to add some heavy duro rubber shims between this and the bed floor. I paired this with the C611-624 gooseneck hitch.

This product is a chucking ENHANCER, not a chucking dampener. Additionally, despite what you have read, my experience with GenY customer service has been terrible. GenY will not support their warranty program, they will try to tell you everything is OK, when the fact is, their product is faulty and does not function to GenY product literature statements “Built-In Suspension Creates Up to 90% Smoother Ride”. I purchased the GenY executive hitch from eTrailer on 3/10/23, etrailer sent the wrong unit and to etrailer’s credit - they quickly took responsibility and replaced with the correct unit on 3/24/23. I installed on my DRV Elite Suites PS3 just in time to attend the SOITC rally at the Outer Banks on 4/13/23. When we left for this 750-mile one-way trip, the GenY load indicator was in the middle of the green zone, I measured the pin load at 5,200 pounds. Bedrail clearance was my reason for buying the GenY, it replaced a Trail Air on my DRV and a Reese 27,000-pound hitch on my 2022 F450. Bottom line, the GenY system provided no improvement in bedrail clearance, but did offer the ability to switch in different gooseneck balls to adjust for bedrail clearance. GenY states that a 1,000-mile break in period is required before the GenY torsion system is fully effective. My experience was that at 750 miles the torsion system on the GenY had sagged to it lowest point with the load indicator in the unit outside of the green, this also resulted in losing nearly two inches of bedrail clearance. It looks like it has a metal-to-metal stop so that the lowest the indicator will go is to the white lines outside of the green. I called GenY from the RV park and was told that the unit would not sag further. I purchased a Curt gooseneck ball which was 2 inches higher than the Ford ball to regain bedrail clearance having to rapid ship it to the RV park. Chucking became downright scary on the 750-trip home. As an example, chucking was induced every time my truck’s ten-speed transmission shifted up. Upon arrival home, I again contacted GenY customer service with a full expectation that GenY would replace the unit. Instead, here is their response: “I spoke with our QC Manager regarding your hitch. He said that you are in the correct unit and being at the top end of the green is normal after the break-in miles. As for the bedrail clearance he said that you would be able to lower the pin box down a set of bolts (with our pin boxes you are only required a minimum of 4 grade eight bolts per side) or use a B&W ball as they are roughly 1 1/2” taller.” This is unacceptable...

Without a doubt the biggest difference maker I have ever used in my 50 plus years pulling trailers. When my wife had to concede that the Gen-Y gooseneck hitch made such a drastic difference.... enough said!

The Gen-Y gooseneck has been excellent! I now have approximately 12k miles on mine and it rides very nicely with very limited chucking and handles rough roads very well. I’d highly recommend that you contact Gen-Y BEFORE ordering to ensure you get the correct load rating product. Gen-Y and Etrailer have provided excellent customer and tech support! This product definitely frees up your truck bed and does require a precise line up to hitch.

Makes life a lot easier l don’t have to remove my hitch from the bed of my truck to use it. Just flip the ball and there you go. The gooseneck hitch actually pulls better than the 5th wheel hitch I had. It is rather heavy so come up with a good plan for installing, I used the front end loader on my tractor which allowed me to do the install by myself. Great product!!!

I bought this adapter again because I had one on a previous trailer - and it worked great. I like that it screws on rather than only bolting on. Then I really know it's secure.

I love this hitch I put it on my 35’ Astoria fifth wheel it pulls great and the shock absorbers help with a smooth ride.we took a ten day trip from Ga to Maine last September and had no problems with this hitch. I guess the only negative is that it’s not as easy as a regular fifth wheel hitch to hook up by yourself but after a few times you can line it up ok. The best thing is that no big hitch taking up space in my truck bed just a ball

Order arrived on time. Packaging looked almost perfect with one corner of the box slightly damaged. Two of us installed the hitch without too much of a problem. It is heavy. Used some WD40 on the inside of the mount. Balance it on the tailgate of the truck. One strong man plus an old guy was able to get it installed. I will update this once we have a couple thousand miles on it.

Came just as they pictured it an on time

Great product, fast shipping, excellent communication, definitely recommend these guys!! We painted the square tube/king pin tube red and installed it. Works great, but there is not much of it to see in the pic. Take my word, well built & very heavy duty!!

This product is spot on, I installed it immediately and have used it twice. This product was an awesome option to purchase because of already having the B&W turnover ball system. This gave me the ability to install and the Curt Q24 slider to give the maneuverability needed when pulling a fifth wheel with a short box that the Anderson hitch did not provide. I have already used the slider option twice, it works flawlessly. Prior to the purchase of this Demco I purchased the Curt X5. The X5 did not work with my truck at all. The X5 did not even make contact with the bed of the truck for support. This Demco base to rails fits tightly to the bed of the truck. I have 2007 Dodge 3500. It is a short box mega cab.

Does exactly what is is built to do. I pull a 42’ fifthwheel that weighs 18000# with no hesitation anywhere. As always very happy with product and ther staff at etrailer. I will continue to use you for all my needs. Thank

Man,this thing is GREAT! It was 1 day late on delivery, but other than that, it bolted right up using the existing holes, NO DRILLING! I was THRILLED! It works as advertised, the powder coat paint is awesome, the auto latch works flawlessly. I am very pleased I would recommend anyone wanting to switch a 5th wheel kingpin to a gooseneck to use Gen-Y. They got their act together!

product delivered quickly and packaging was in tack. installation was pretty easy using a tractor. the ride was much improved over a sliding standard pin box system. this system opens up the rear bed space and and allows the ball to be removed like nothing was ever installed. I used the 4 inch offset from B&W to help turning radius on our short bed Ram also devivered from e- trailer. great customer service
