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.

  • 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.

  • Will Curt A20 5th Wheel Hitch Work with Reese Sidewinder 5th Wheel King Pins
    I do have an option for you but the Curt A-Series 5th Wheel Trailer Hitches like part # C16140 are only compatible with the first generation Reese Sidewinder 5th Wheel King Pins, not the second generation Reese Sidewinder 5th Wheel King Pin because there was an issue with the wedge shearing off during testing. If you have the first generation then you can use the Sidewinder Wedge for Curt A Series 5th Wheel Trailer Hitches part # C16992 but if you have the second generation then you will...

  • 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...

  • 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.

  • 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.

  • Curt E16 5th Wheel Hitch and Base Rail Compatibility with 2017 Ford F150 5-1/2 Foot Bed
    The Curt E16 5th Wheel Trailer Hitch # C16115 will fit the industry standard base rails compatible with your 2017 Ford F-150. If you don't have the base rails yet, then I recommend the Reese Quick-Install Custom Installation Kit w/ Base Rails for 5th Wheel Trailer Hitches # RP50087-58 confirmed to fit your truck. These brackets won't require drilling into your truck frame. If you want to use the kit # C16116, it will work with your truck, but you will need to drill into your frame for...

  • Solution for Front Axle of 2018 Ram 2500 Transferring Weight to Rear Axle
    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...

  • 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...

  • 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...

  • 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...

  • Can Anderson Ultimate 5th Wheel Hitch Be Used With Sidewinder Pin Box
    I have another option but unfortunately neither the Anderson Ultimate 5th Wheel Hitch or the B&W Turnover ball gooseneck hitch are compatible with a rotating pin box like the Reese sidewinder you mentioned. 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...

  • 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 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.

  • 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...

  • 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.

  • 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.

  • 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 90º turns with the recommended 4 inches of clearance between the rear of the truck cab and the front...

  • How Do Rotating Pin Box Wedge Kits Work And How To Choose The Correct One For Your Setup
    Hi Steve, The wedge kit is designed to prevent the king pin from rotating inside of the jaws to force the pivot point back to the turret of the Sidewinder for additional turning clearance. Most rotating pin boxes will come with a generic rectangular-shaped wedge kit to fit the variety of hitches on the market but there are specific fit wedge kits designed to spread this force out more evenly across the funnel of the hitch head. The wedge handle should only need to be adjusted on the initial...

  • 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 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.

  • Are The Curt Q-Series Fifth Wheel Hitches Compatible With Sidewinder Pin Boxes
    The little tech note on Reese's page is worded a bit misleadingly. The Sidewinder Wedge Kit for Curt E-Series Fifth Wheel Trailer Hitches # RP64FR you were looking at is only compatible with the Curt E-Series hitches, which is why it says not to use with the A-Series. The Q-Series hitch heads are not compatible with the stress that a Sidewinder would put on it which is why we list it as not compatible.

  • 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.

  • What Is Needed to Tow 5th Wheel Trailer With 2020 Ford F-150 With 5-1/2 Foot Bed
    You can tow a 5th wheel with your 2020 Ford F-150 with a 5-1/2 foot bed, but you will need a standard/fixed 5th wheel hitch and a Sidewinder rotating pin box. The reason for that is the Sidewinder will move the pivot point back to the turret, which allows for the needed clearance so your 5th wheel trailer does not crash into your F-150's cab. The correct Sidewinder will depend on your 5th wheel trailer's pin box model number, as you'll need that in order to know the correct fit. For a...
