Video Transcript for Curt Gooseneck Trailer Hitch Review

Jake: Hey guys, it's Jake here with etrailer today. We're going to be taking a look at two different Curt products, but they're going to accomplish the same thing. We're going to be looking at the curd spider and the Curt drop-in plate. Both of them are going to be a gooseneck conversion for your fifth wheel rails that are already in your bed.Now what I like about this is let's say you have a fifth wheel camper that you go camping with for the past couple of years. And you decide that you want to either haul a gooseneck trailer because you got a side project coming up or something like that, but you don't want to take out your bed because you still like going camping. This is designed to help you haul goosenecks in the proper way, by just utilizing the rails that are already in your bed.The first difference is going to be that our safety chain loops on our spider are going to be on the front and they're going to be spring-loaded, just like our standard ones are on your regular goosenecks.

Can be spring-loaded, pull it out, hook your safety chain on there, and you're ready to go. The ball is another area of concern. So the gooseneck ball on our spider is going to sit directly in the center of our two rails. It's also going to sit from the bottom of the spider to the top of the ball, is going to be about seven and a half inches. Let's go ahead and take a look at the Curt plate for gooseneck adapter and show you the difference.

With our Curt plate. You can see that our safety chain loops are incorporated in the plate itself. You just simply hook your safety chain hooks onto these loops, and it's going to be safe to travel down the road.You're going to notice that our ball is going to be slightly offset either to the front or the rear. We can flip this plate around depending on what kind of vehicle that we're towing it with. If we have a long bed, it's not really going to matter which configuration you use it for.

You are going to be able to use it with the ball facing the cab, or more towards the cab. And if you have a short bed truck, which you can do, is you can take the whole plate and have these handy little grip slots that you can put your hands so you don't smash it in between the bed and the sides of our plate. Simply lift it up, spin it around, set it down, and you can see very easily. We just gained about six inches back and neither of our balls are going to be in the center of our two rails.So this is going to give us that extra cab clearance that we need for the nose of our trailer, if you're hauling it in a short bed. The biggest difference between the two gooseneck adapters I'll have to say is going to be the height of your ball.

The height of our ball on our gooseneck plate here is going to be only from the top of your rails to the top of the ball is only going to be about four and a half inches. So you can tell the difference between the sheer size of our spider and our plate is that you're going to gain about three inches if you're using the spider. Whereas if you don't want to have to adjust your coupler on your trailer, or if you can't adjust it enough, we've gotten a lot of reviews that say that they cannot put their coupler any further up inside their gooseneck hitch.So they're going to have to go with the plate because the spider was simply too tall. They couldn't adjust their trailer to the right height to haul it level. Both the hitch adapters are going to install the same way; simply lift it up and drop it into place. Both the spider and the gooseneck plate are going to come with four pins so that you don't have to rely on your pins from your fifth wheel to be able to get it locked into place. Both of the hitches are going to have the same weight capacities. It's going to have a 25,000 pound gross towing weight and a 6,250 pound tongue weight. Both of these hitches are going to have a carbide black powder coat, which is going to be stronger than just your standard powder coat. You're not going to have to worry about it, shipping or flaking, and then potentially rusting your hitch.With that being said, the hitch is made of a sturdy steel construction. And it will say Curt did a very good job of making this out of a very thick quarter inch steel. So when it comes down to it, they're both going to be made out of the same materials. The spider is going to be a little bit heavier and bulkier to put down into place, and it's going to stick up higher, as we went over. They're both going to feature a 2 5/16 ball. So you're not going to have to worry about them being different in that aspect. What it's really going to come down to is what are you using it for And what are you using it with If you have a short bed truck and you have a camper that you're towing with this and that your camper has a gooseneck coupler on it, or maybe you have a horse trailer that has a larger nose, and you'd like a little bit more space for the cab of your truck to have some more clearance. I would definitely go with the Curt plate. If you have a long bed truck, or you have a short bed truck, but you're just hauling a trailer with a simple gooseneck coupler on it, and you don't have any clearance issues. Then I'd go with the spider.

Curt Spyder Gooseneck Trailer Hitch for Fifth Wheel Rails, 25,000 lbs GTW - 16085

Average Customer Rating:  4.9 out of 5 stars   (297 Customer Reviews)

- 16085

I have a fifth wheel hitch already and needed to tow Gooseneck trailers. Was able to use fifth wheel base and mount Gooseneck hitch right to it. Works great.

- 16085

I bought this gooseneck Hitch back in 2016 I can't say I've used it everyday of the week but I do use it pull a cattle trailer occasionally and I've used it to pull 20,000lbs of silage bales out of the field and it's held up great no stress points or anything showing paint has held up great. It's a very heavy built hitch I would deffenitly recommend it to anyone that has the rails in there truck and is doin pretty stressful towing. It also sits the trailer up a lil higher and I love that really helps with twisting and turns.

- 16085

it fit our Reese 5th wheel hitch rails perfectly. We hooked our gooseneck 4 horse trailer to it and it pulled just fine.

- 16085

As tough as they get! Hauled over 60 tons of road base using it and my tandem dual dump trailer. Last load believe it or not my 2006 Dodge 3500 1 ton truck, trailer and rock came in @ 42000 lbs. Touch overloaded, but otherwise everything held up well. I bought this type of hitch for my farm truck as it already had the rails for a fifth wheel setup, also a Curt 15K hitch for RVs. Good product! Will purchase from e-Trailer again when I get ready for a hidden hitch in my 2015 Ram!

- 16085

Just got my gooseneck trailer hitch for 5th wheel rails. Very good packaging, awesome service it arrived a day earlier than expected. Hopefully I get to try it out this weekend. It looks well built.

- 16085

Really, really like this hitch! Replaced a Draw-Tite arch hitch with this one. The Spyder has a little more rise to it which helps the trailer sit and clear the bed a little bit better. I like the weight of it, easier to handle and remove/install. The integrated brake away hooks for the safety chains are a big plus. Highly recommend and would purchase again.

- 16085

Received my hitch in just a few days, haven’t used it yet. I’m glad products like this exist so I can hook up to a gooseneck. I chose this one because I have curt rails and I like the spring loaded safety chain loops.

- 16085

Sturdy built product. Didnt exactly fall into my rail slots but a few whacks with the BFH while standing on it and it aligned. Great option for getting a gooseneck ball in truck bought with fifth wheel rails compared to putting whole new ball hitch in. Ordered 2-24 arrived 2-26.

- 16085

Well made and fit perfectly into existing 5th wheel rails. Have only used once but the capacity of the hitch exceeds my trucks tow rating so am not expecting any issues. Much easier and cheaper than other options when you already have 5th wheel rails.

Have used the hitch to tow a flatbed gooseneck trailer loaded with 20ft logs over an 8500 ft mountain without worry. Very robust construction, should last several lifetimes!

Very very pleased worked perfectly with my rail system and is super easy to install. Very fast delivery with just the free delivery ordered on 4/13 and received it 4/17.. only thing i will say is its a little taller then i thought it would be but on a non lifted truck there would be completely no problem my truck does have a lift so does make the trailer sit more unlevel then a flat bed mount would but im still extremely pleased with it... will definitely use this company again for anything i need...

- 16085

Awesome service really fast shipping. Product seem really nice.

- 16085

I have been an E trailer customer for over 8 years now. I was not surprised when my hitch showed up ahead of schedule and installed with ease. Great work from a great company.

- 16085


- 16085

It has worked very well for what I need, I like to be able to switch back and fourth from gooseneck to fifth wheel, this is a great product highly recommend it!!!

- 16085

I am very happy with this product. The only negative thing I would have to say is that it is a pain to hook your safety chains.

- 16085

I installed this in minutes and it is just what I needed because my travel trailer fits over this hitch at same time so I always have this hitch in truck. It looks good to me also. It is a solid made product so I have no Cons for this unit. I would recommend this for any one that does not want to change his fifth wheel rail type mounts to the expenses hid away hitch to use a goose mount hitch.

- 16085

Works perfectly with my Reese 5th wheel rails.

- 16085

Fit perfect first time. The Reese hitch was welded together so bad its going to scrap.

- 16085

Gooseneck hitch arrived in perfect condition Very fast Delivery and I’m very Happy about the product. Thank you

- 16085

Wow, fast delivery and fits snug in the rails. Very impressed with adaptor and customer service. We use it to pull a 16 ft. Livestock trailer. Way better then a bumper pull for us.

- 16085

Excellent product; meet every expectation! Fit as advertised right into my existing bed rails. Now I'm ready for any type of trailer, gooseneck or RV. Very timely delivery; thank you etrailer!

- 16085

It's a super nice gooseneck hitch easy to install works great for hauling pur hp Horsetrailer

- 16085

I bought it originally to take in and out of my existing rails to have better use of my bed, but it was bit tough to get in so I just left it in. Very durable and has met expectations for use otherwise.
