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   (34 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:

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.

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

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:

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:

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



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:

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

Part looks good. I have not used it yet though

  • Does Sidewinder Pin Box Wedge Need to Be Adjusted Each Time Before Towing
    You may not need to actually adjust it, but you will want to check your Sidewinder Wedge Kit # RP64FR for correct placement and torque prior to towing each trip (see attached instructions for Sidewinder pin box). This is the case no matter what wedge you're using.

  • Adjusting the Wedge on a Sidewinder/Revolution Pin Box For a Curt E16 5th Wheel Hitch
    When installing a wedge for a Sidewinder, it is important to make sure the wedge is making contact with the opening of the fifth wheel head. Check out the photo I attached showing how the universal wedge should fit in a head. Keep in mind, this is a universal wedge, so there may be a small gap, even if the wedge is all the way against the king pin. For a better fit, I recommend using the Custom Wedge for the Curt E16 Fifth Wheel Hitch, # RP64FR. This wedge was designed to fit the Curt...

  • Reese Sidewinder Pin Box Wedge With 3/4 Mounting Hardware For a Curt A-Series 5TH Wheel Hitch
    Since you have the newer Reese Sidewinder 5th Wheel King Pin # RP34FR, you will need the Wedge Kit # RP64FR. This will include the 3/4"-10 bolts that you have on your Sidewinder and fits E-Series Curt 5th wheel hitches.

  • Custom Wedge for Reese Revolution/Sidewinder Pin Box and a Curt E16 5th Wheel Trailer Hitch
    There is a wedge for the Curt E16 5th wheel trailer hitch. You will need custom wedge # RP64FR. Considering the weight and stresses involved in 5th wheel towing, be sure to inspect the wedge, hitch, and pinbox before each trip.

  • 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.

  • Can a Curt E Series Fifth Wheel Hitch be Used with a Sidewinder
    The Curt E16 Slider hitch part # 16516 can be used with a Sidewinder like the part # RP34FR that you referenced. The Q Series of Curt hitches have a very wide jaw that prevents it from being compatible with a Sidewinder. The E series has more of a standard jaw design so it can be used with a Sidewinder. The correct wedge kit you would need is part # RP64FR for your fifth wheel. If you had a Q16 hitch you could use the new wedge part # C16992 though.

  • 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.

  • Replacement Pin Box For A Reese 10K Revolution Pin Box
    The Reese 10k Revolution was a uniquely designed pin box that can only be replaced with another 10k Revolution. Your 10k Revolution is a sidewinder so if you're using a slider it must be locked out. You can unlock it by removing the lock out bolts like you can see in the attached picture and adding on a Sidewinder Wedge Kit for Curt A-Series and E-Series Fifth Wheel Trailer Hitches Item # RP64FR and locking out your sliding hitch. Doing this will move the pivot point further back than the...

  • Is Curt Q20 5th Wheel Hitch Compatible with Reese 5th Airborne Premium 5th Wheel Air Ride King Pin
    I do have a solution for you but unfortunately the Curt Q20 hitch head is not compatible with a pin box that has a rotating turret like the Reese 5th Airborne Premium 5th Wheel Air Ride King Pin. This is due to the spherical axial bearing that allows the hitch head to easily pivot. Instead, I would go with the Curt E16 5th Wheel Trailer Hitch - Slide Bar Jaw - 16,000 lbs # C16115 and Wedge # RP64FR. The wedge will keep the king pin from rotating inside the fifth wheel hitch and this setup...

  • 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.

  • Recommended Sidewinder And 5th Wheel Hitch For A 2016 Ram 3500 And Grand Design Momentum 5th Wheel
    For the fifth wheel hitch I recommend Reese M5 5th Wheel Trailer Hitch - Single Jaw - 20,000 lbs # RP30928. If your 2016 RAM 3500 has oem prep package then you'll also need Installation kit # RP30154. If there isn't a prep package then you'll instead need installation kit # RP50085-58. Unfortunately, there is not a rotating pin box that is rated higher than 20,000lbs so you will need to ensure you stay under the 20,000lbs when loaded to safely tow your 2019 Grand Design Momentum 376TH...

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.

  • Custom Wedge for a Sidewinder and Curt E-16 5th Wheel Trailer Hitch
    If the universal wedge you are using with your Sidewinder did not lock out the pivot point of the trailer at the hitch, which is what the purpose of a wedge is, then that is what would have caused the problem. When the wedge locks out the pivot point that will allow the trailer to pivot 22 inches further back. But the turret on a Sidewinder (which is where it pivots 22 inches back) can also be locked out. So if the wedge was not in the right place and the turret was locked out the trailer...

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.

  • Problems Unhooking Trailer with Sidewinder King Pin from Curt 5th Wheel Hitch
    You may want to check out the Sidewinder Wedge Kit for Curt E-16K Fifth Wheel Hitch # RP64FR. If you are using a universal wedge, it could be your problem. Curt also offers a wedge for the E16, part # C16991. I recommend the Reese wedge # RP64FR. This wedge is more of a custom fit than the Curt # C16991 wedge.

  • Does Reese Mounting Bracket for 5th Wheel Trailer Hitches # RP58023 Fit a 2012 Ram 3500
    Bracket # RP58023 does fit the 2012 Ram 3500. It comes with installation kit # RP30035-023. You mentioned that your truck has the Ram Box feature. There are specific parts needed to be able to tow a 5th wheel trailer on Rams that have the Ram Boxes. Basically, because the bed on Ram Box models is narrower than on the standard beds, what will happen is during a turn the pin box will hit the bed sides. To prevent damage to the truck and trailer the fix for this is to use a stationary 5th...

  • 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.

  • 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...

  • Is Using a Custom Wedge with a Sidewinder a Better Fit than the Universal Wedge
    When using a Sidewinder pin box, you unfortunately can't use a Curt A-Series anymore due to a new design. Instead, you can use a fixed hitch like the Curt E16 5th Wheel Trailer Hitch - Slide Bar Jaw - 16,000 lbs # C16115. You'll want to use Wedge # RP64FR with this Hitch and a sidewinder. This custom wedge will be the best fitment when it comes to the Curt E-Series hitches.

  • 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.

  • Best Sidewinder Wedge Kit Fit for the Curt E16 5th Wheel Trailer Hitch
    I reached out to my contact at Curt and they advised me that once you actually bolt the Sidewinder Wedge # C16991 on the Sidewinder there should not be any wiggle room. The Sidewinder Wedge Kit for Curt E-16K Fifth Wheel Hitch # RP64FR will provide the same fit as the # C16991. I recommend using the # C16991 or the # RP64FR instead of the Universal Wedge because they are specifically made for the Curt E16 5th Wheel Trailer Hitch.
