Video Transcript for Curt E16 5th Wheel Trailer Hitches Sidewinder Wedge Review

Hey guys, Kevin here with etrailer and today we're gonna be taking a look at the custom fit Sidewinder wedge kits for the Curt E16 5th wheel hitch. As you can see, we have three different custom fit wedge kits. Four are E16 and there are a little bit of a difference in the designs. These two right here, we have our Curt and then we have two Reese ones. These are gonna be more like what you'll see generic that comes with your Sidewinder, or maybe if you have a Lippert Turning Point, you'd see some kind of generic wedge like that. And these are pretty typical, pretty easy to put in place.

So whenever you lock in your king pin into the hitch head, this Sidewinder wedge is going to come up and slip into place. And what it does is it prevents the kingpin from being able to turn. So when our Sidewinder's in place we're not gonna have two pivot points because we want that pivot point to be pushed back at the connection point at the trailer so that we gain that extra turning clearance. Now with the different designs each is gonna give you a little bit more pressure on the funnel itself and that's just gonna kinda take off the pressure from a certain other point. So if you have too much pressure on one side you can kind of get a little bit more wear and tear on it versus these custom fit wedges where it's gonna kind of fit and fill in that funnel and just kind of spread out that pressure.

Now with the Curt one, obviously with it being just a rectangle shape, it's only gonna slip in there. It's not actually gonna touch the funnel at all. With this Reese one here, you can see it's kind of a fan shape, so it kind of fits that funnel a little bit better. So it's gonna put pressure all along it and spread it out evenly. Now with our other Reese one here, I was having some difficulties.

The paint that they put on it is pretty thick so me pushing it up against it isn't really getting it to pop in place. Obviously when you back your truck up to the trailer and you get it in, it'll pop right in. But you may see that on this specific wedge. I tried a couple of them, they all seem to have a little bit too much paint on 'em. But same concept here, basically this rectangle portion's gonna pop inside of our hitch head and then we'll have this slanted portion pressing against the funnel.

Now I don't want to kind of push you away from your generic Sidewinder wedge. You can still use that. It's still safe. I just prefer to use the custom ones and I always recommend them just because it just evenly distributes that weight across the whole hitch head and I just prefer to take that extra step and keep my hitch looking nice and brand new. Now with these, it's a simple two bolt installation. You'll notice on one side it kind of has a divot in, that side is going to have the bolt head. So when we're looking at our pin box we would have this side facing down. The bolt would slip through and screw into the plating into our pin box. Here we have the same setup but this one also has a little track on the outside so it kind of keeps it in that line. And same thing with our other one over here. This one's got a little bit less to it. This one's pretty flat with just a little bit of space in here. And you can see there's a little bit of a weld spot on there to kind of separate the two bolt heads. Now we've gone over some of the specifics of our wedge kits. Let's go ahead and show you how to install it. So here we have a trailer with a Reese Sidewinder. Here's the generic like rectangle-shaped Sidewinder wedge kit that's typically gonna come with your Sidewinder. If you look back here, you can see the rotary wheel. And what this does is it allows our wedge kit to kind of move back and forth so that we can kind of fine tune exactly where it needs to sit. So if I pull this pin out and I turn it, so turning it counter-clockwise here, if I'm facing towards the trailer, is gonna push it forward more towards the king pin. And then if I put it back clockwise, we can get it kind of back towards the trailer. Now one little tip I do recommend doing is once you find that sweet spot of where this needs to sit so that it properly aligns in the head of the hitch, go ahead and just mark it. So like our neighbor today, they've already marked it. You can kind of see it, it's a little bit scratched up just from connecting to the hitch but there's a yellow marker on here, so that way you know exactly where it needs to sit every single time. You can easily put it back to where it needs to be and pop your clip back in. But let's go ahead, we'll take this off and show you how to put on a new one. So here is our old generic Sidewinder wedge kit. If you see right here, it has one less tab on it, on this part. This is gonna be facing towards our hitch 'cause it's gonna kind of overlap the head a little bit. And then it'll stop right about here. So with our new one, we're gonna copy that as well. We'll have that facing towards our hitch. And I'm gonna go ahead and just reuse the same bolts. So we'll go ahead and get down under our pin box. And right here is that little plate I was talking about that we can bolt into. Go ahead and place our wedge up here. Just hand tighten that in for right now, so we get this fully set and then we can use our wrench. Once we have 'em pretty tight we can go ahead and torque 'em down. Also, gonna go ahead and back this one up a little bit. This is a little bit larger than our last one, so we're gonna need to push it out of the way. We'll hook up to our kingpin and then we'll go ahead and select this into place, get it in the right position. Now we're hooked up to our hitch, we can go ahead and start turning our rotary wheel and get it fully locked up in position here. Pretty tight. All right, once we got in a position that we like, you can go ahead and slip our pin back in place and we're good to go. Well, I think about does it for today's look at our custom fit Sidewinder wedge kits here for our Curt E16 5th wheel hitch. My name's Kevin, thanks for watching.

Sidewinder Wedge Kit for Curt E-Series Fifth Wheel Trailer Hitches - RP64FR

Average Customer Rating:  4.7 out of 5 stars   (43 Customer Reviews)

Bolt this wedge onto your Reese Sidewinder (68220) to prevent the Sidewinder's king pin from rotating in your Curt E-Series fifth-wheel trailer hitch.

by:

The Reese Sidewinder (20k) setup I use with my 2022 Ram 2500 with a 6.5ft bed has been fantastic! I paired it with the Curt A25 and the OEM puck bracket to pull my 43' 15500 GVW 5th wheel, and it does not disappoint. No need to slide my hitch or worry about cab contact for sharp turns. I can turn 90deg with no issues if needed and have experienced very little line up issues getting it hitched up (mainly a result of the factory air ride releveling before the king pin fully seated in the hitch head). Great engineering by Reese all the way around! For those who will ask, no additional trailer sway and no turning limitations.



by:

Had to take a metal file to remove some of the welded spots and paint for a proper fit. Manufacturer should take time for Quality control and proper fitment.



by:

Having a Ram 3500 Megacab, short bed, I was terribly worried about hitting the cab with my Momentum toy hauler given it's 102" wide. My choice was slider or this Reese Sidewinder. I chose the Sidewinder and darn glad I did. It works as advertised and I can turn a full 90 degrees with about 5" of clearance between the cab and my front nose of the trailer. Some words of caution: this pin box is heavy! Get it professionally installed by your RV dealer. The wedges for your particular hitch will take some getting used too. Move wedge back to hitch, move forward to lock into place. Even still, I need to lay in the bed and have rigged up a heavy wire to assisting getting that wedge tight in the funnel. If you don't, the hitch will move on corners and you feel a big shift of weight.

Bottom line, I like it, it was the right decision for me and didn't take up any more payload than necessary unlike a heavy slider hitch. Recommended! And etrailer delivered on time as promised.



by:

I received the part I ordered the 1st time, the gentleman that took the order did a great job. When I called to follow up people were awesome with customer service.

Great, but it is the same as the standard wedge that came with my Sidewinder.
I will need to return it.

Didn't fit my hitch. Doesn't have track.

The staff was very helpful and friendly. They made sure that I was ordering the right parts.

Parts where on back order per information given by my 2 other vendors etrailer had it in stock and arrived on time before original ETA
As a owner of a small business etrailer is great to work with and always helpful.



by:

I am giving it 3 stars because I was told, by etrailer, I needed it for my Sidewinder pinbox. You do NOT if you are using the pinbox with a Reese hitch. The Sidewinder comes with the Wedge kit bolted to it.



by:

I needed this due to the model of hitch I have. Works great! Installation instructions were spot on.



by:

Looks good will install tomorrow



by:

This wedge kit works in conjunction with the Reese Sidewinder pin box. The fit was perfect and a very simple install. As always, etrailer had exactly what I was needing and was quick with shipping.



by:

This wedge kit is essential to the Reese Sidewinder pin box. It works great and, as always, etrailer has great service getting me this item in a crunch.



by:

The wedge kit needed to use the Sidewinder has been amazing. I can't say enough about the whole Sidewinder hitch system. Makes towing, parking, even showing the hitch a breeze



by:

Sidewinder worked great for my short bed Ram. Be sure to get the matching wedge for your hitch.

Thanks etrailer. I will be using you for all my trailer components



by:

Part looks good. I have not used it yet though



by:

She assisted me promptly and accurately thank you for being so fast and helpful



by:

Nice hitch and good people to deal with

What I expected. Great quality.

  • Troubleshooting a Curt A16 5th Wheel Hitch Not Hooking Up Smoothly to a Reese Sidewinder
    I have a suspicion on what the issue could be. There is a good chance that the 5th wheel hitch and wedge are not compatible with the Sidewinder. It at all comes down to what Sidewinder you have. If your Sidewinder is the more current model (68220), then the Curt A16 5th Wheel Trailer Hitch # C74FR and Sidewinder Wedge for Curt A Series 5th Wheel Trailer Hitches # C16992 would not be compatible. There was a design change between the Sidewinder generations that causes the wedge to sheer...

  • Do I Need A New Wedge To Use A Reese Sidewinder With A Curt 5th Wheel Hitch
    The universal wedge that came with your Reese Sidewinder Pin Box really should not be used with a Curt 5th Wheel Hitch. Instead, you will want to use a custom one as this will provide the tightest fit, part # RP64FR since you have an E-Series Curt 5th Wheel Trailer Hitch.

  • Will Curt A20 5th Wheel Trailer Hitch Work with Reese Sidewinder Pin Box
    I have a solution for you, however, the newly-updated Curt A-Series Fifth Wheel Hitches are NOT compatible with Reese Sidewinders, and they haven't been confirmed to fit other rotating pin boxes either. For this reason, I recommend to a Curt E-Series like Curt E16 5th Wheel Trailer Hitch - Slide Bar Jaw - 16,000 lbs # C16115 which is compatible with sidewinders when used with Wedge # RP64FR.

  • Are Curt Q- or E-Series 5th Wheel Trailer Hitches Compatible with Sidewinder Pin Boxes
    The Curt Q-series 5th wheel hitches are NOT compatible with Sidewinders! They are compatible with the E-series Curt hitches though. I checked your order and you did get a 16K E-Series hitch and wedge kit # RP64FR. The key with the wedges is that they need to be installed exactly as the instructions state. Any other orientation will not work. If the 5th wheel trailer is not tracking straight then the wedge is not in the right position or has come out of the right position.

  • Which Curt 5th Wheel Hitches are Not Compatible with a Sidewinder Pin Box?
    The Curt Q-series and A-series 5th wheel hitches are the only Curt hitches not compatible with a Sidewinder pin box. Instead of these models, you can use something like the Curt E16 5th Wheel Trailer Hitch - Slide Bar Jaw - 16,000 lbs # C16115. If you have the prep package then you'll also need Adapter rails # C47BR. If you don't have prep package then you'll instead need Rail Kit # C16411-204. To swap out your standard pin box with a rotating/sidewinder pin box you will need to know the...

    The Curt E16 5th Wheel Trailer Hitch for Nissan Titan XD Towing Prep Package - Slide Bar Jaw - 16K Item # C16515-16026 will indeed fit your 2017 Nissan Titan XD with the OEM prep package. You'll also need a wedge to prevent the pin box from rotating at its connection to the hitch. If you go with the E16 hitch, use the # RP64FR wedge. In most instances, the Lippert Turning Point will allow 90ยบ turns with the recommended 4 inches of clearance between the rear of the truck cab and the front...

  • Recommended 5th Wheel Hitch For 2013 Ram 1500 5.5 Foot Bed With Rambox
    If you don't already have rails, I recommend the Reese Custom Rails # RP50142-58 for your truck. Once you have rails, I recommend theCurt E16 5th Wheel Trailer Hitch - Slide Bar Jaw - 16,000 lbs # C16115 which will fit with your rails. This hitch has interlocking jaws and a fully articulating torsion head for controlled coupling and a quiet stable ride. This hitch has an adjustment from 13 to 17 inches tall. This hitch will work well with a Sidewinder that is required for a 5-1/2 foot...

  • Can Curt Q Series Fifth Wheel Hitch be Used with Sidewinder Pin Box
    There isn't a wedge that will work with the Q Series of Curt hitches as that hitch is not designed to be used with a Sidewinder. The stress of the Sidewinders ends up damaging the head of the hitch. Instead, you'll want something like the Reese M5 5th Wheel Trailer Hitch - Single Jaw - 20,000 lbs # RP30928 which can be used with a Sidewinder when used with Wedge # RP44FR.

  • Will Curt Q20 Work With Lippert Turning Point Pin Box
    There is a great option for a Curt 5th wheel hitch you can use with your Lippert Turning Point pin box, but the Curt Q20 Fifth Wheel Hitch # C16130 is not compatible. The reason is the head of the Q20 has what is called a "spherical axial bearing" which is really a fancy way of saying it pivots 360 degrees. This means it is not stable enough to work with a rotating pin box such as the Turning Point or a Sidewinder. A very similar hitch that will work with your Turning Point pin box is...

  • 5th Wheel Hitch and Pin Box for 2016 Nissan Titan XD
    If I understand correctly, you have a Curt E16 5th Wheel Trailer Hitch, # C16115 mounted in the back of a 2016 Nissan Titan XD (6.5 foot bed?). You have a Lippert 1621 Pin Box, # LC1387883, on your 5th wheel but not enough clearance for the cab. I get the impression that you have the hitch mounted on Base Rails such as # C16200. If you have a short bed truck you need, at minimum, the Curt E16 Hitch # C16115, mounted on the Curt R16 Round Tube Slider for E16 Hitches, # C16560. Another...

  • Best 5th Wheel Options For A 2001 Ford F-250 Short Bed
    Pretty much all of the above bed rails made today are an industry standard design to accept most brands of 5th wheel hitches but there were a few older above bed rails out there that were specific to their brand. In order to ensure a proper fit you will need to measure the distance between the mounting slots. I have attached a photo on how to properly do so. The only auto-sliding 5th wheel hitch options we have available is the Demco Hijacker Autoslide 21k part # DM8550035. Available in...

  • Curt Fifth Wheel Hitch That is Compatible with Sidewinder
    A Curt Q24 fifth wheel hitch such as # C16245 is not compatible with a Sidewinder and should not be used with one. The reason for this is its spherical axial bearings in the hitch head of the Q24; there is far too much movement in the head unit to be safely compatible with a pin box that rotates. This is also the reason there is no a wedge for the Q Series of hitch. The best option is really going to be a new fifth wheel hitch. While I know that is not what you expected, it is the safest...

    The B&W # BWGNXA2062 Gooseneck Ball and Safety Chain Anchors for Ram Under Bed Gooseneck Hitch would indeed be compatible with the Demco # DM8550045-5W Recon 5th wheel hitch, but it might not be the correct setup for you. With a short bed truck like yours you'll need to use a sliding 5th wheel hitch to prevent the front of your 5th wheel from contacting the back of the truck cab during turns, unless the front corners of the 5th wheel are dished in. Also, the Recon isn't compatible with...

  • 16k Fifth Wheel Hitch Recommended for Use with Reese Revolution Pin Box
    The Curt Q series of fifth wheel hitches cannot be used with Reese Revolution or Sidewinder pin boxes because the jaws are too wide on the hitch. I spoke with my contact at Reese to confirm this. One option would be to go with the E16 hitch you referenced part # C16115 and then the wedge part # RP64FR. Or for a hitch more similar to the Q16 in features I would go with the Reese 16k Fifth Wheel part # RP30047. This has a 2 jaw system as the Q16 so it would provide a smoother ride quality...

  • Is There a Wedge that Fits Curt Q20 Fifth Wheel Hitch
    There isn't a wedge that can be used with the Q Series Curt fifth wheel hitches. The Q series of hitches cannot be used with Sidewinders as their jaws/head will get permanently damaged. Instead, you'll want to use something like the Curt E16 5th Wheel Trailer Hitch - Slide Bar Jaw - 16,000 lbs # C16115 with Custom Wedge # RP64FR.

  • Is There a Sidewinder Wedge that Fits Curt Q Series Fifth Wheel Hitches
    The Q Series of Curt fifth wheel hitches can't be used with Sidewinders as the jaws and heads end up getting damaged. Instead, I recommend using the Curt E16 5th Wheel Trailer Hitch - Slide Bar Jaw - 16,000 lbs # C16115 with Wedge # RP64FR. The wedge keeps the king pin from rotating inside the hitch and will work great with your sidewinder.

    Since you have a Sidewinder pin box on your 5th wheel trailer, you will need a new 5th wheel hitch since the current models of the Curt A-series and Q-series are not compatible with sidewinders. Instead, you can go with the Curt E16 5th Wheel Trailer Hitch - Slide Bar Jaw - 16,000 lbs # C16115 and custom wedge # RP64FR. This should help put the front end of your Ram lower since the legs are almost 100 lbs lighter than the slider but I can't guarantee that your pickup will be at factory...

  • Determining The Correct Gen-Y Pin Box For A 2018 Keystone Raptor 426TS
    Hey Daryl, To determine the correct Gen-Y pin box or pin box to gooseneck model for your Raptor you'll first need to determine the pin box bolt pattern for your trailer. There's typically a white sticker somewhere on the pin box that lists the Serial #, RPO #, and LCI item # that we can use to determine the bolt pattern. If not then you'll need to measure the bolt pattern using the guide I've attached below. The next step is to measure the pin weight of your trailer when fully loaded....

  • 5th Wheel Trailer with Sidewinder Pin Box Chucking in Curt E16 Hitch
    Yes, what you are describing is normal for 5th wheel hitches that use a slide bar style jaw. The slide bar allows for a lot of play between the pin box king pin and the hitch jaws. But to be sure, make sure the jaw is fully closing and locking into place. Check the king pin on the Sidewinder for excessive wear as well. There shouldn't be hardly any wear on the Sidewinder king pin though because it is locked out at the hitch by the wedge. It can still move back and forth though. Normally...

Instead I recommend using the B&W Companion Slider Gooseneck-to-5th-Wheel Trailer Hitch Adapter # BWRVK3400 which will install into the B&W Turnover ball already installed on your 2017 Ram Short Bed, and will give you 12" of front to back travel for additional clearance when making...
