Video Transcript for Review of Reese Accesories and Parts - Sidewinder Turret Spacer - RP97FR

Michael: Hi there, I'm Michael with Today, we're going to take a quick look at the spacer kit for your Sidewinder fifth wheel kingpin. As you know, the Sidewinder is a great option for those of you who have short bed pickup trucks that are wanting to haul a fifth wheel. It's going to offset that pivot point, so it's going to give you more maneuverability so that as you're making tight turns and those sort of things, your trailer isn't going to come in contact with your cab. But the Sidewinder does have set dimensions. So if you do have a wider wing set, like any of those that you see on the screen there, you will need the spacers to make sure that everything is going to fit nice and snug and be safe.Now, these are a black powder coated finish, sturdy steel construction so they're going to hold up well, last a long time.

These are going to attach to the turret on your Sidewinder with the roll pins here and they just slide in place and that's going to keep them connected. So you're not going to have to worry about installing these every time or anything like that. It's just going to stay in place and make it just a little bit wider so that it fits in well with those wing plates that you already have. This is right about a quarter inch thick. Can hold the ruler up here so you can see, right about quarter inch in width.

So between the two of them, will take you up to about a half inch and you're going to get two of these plates as well as four of these roll pins and a set of instructions to make sure that you're getting everything installed correctly.Basically the short version is, you can see these little notches in the plate here. So the two notches here indicate that this is the bottom and the notch here indicates that this is the back. So you want to make sure that you get that installed on your Sidewinder with this on the back and these on the bottom and everything should line up perfectly for you. So if you do have that Sidewinder, you need a little bit more space to make sure that everything's going to stay nice and secure. This is the kit that you're going to need.

It does come with a limited lifetime warranty. So if you we're to have any problems with them, you could give us a call, we'd help you out with that.But I really think these are going to be a great option for you. You're not going to have to worry about rattling or just not being safe in your connection. So this is going to be the kit for you. So that's going to complete our look for today.

Again, I'm Michael with Thanks for watching..

  • How to Determine Pin Box to Replace With Sidewinder
    There are a couple of different ways to determine the pin box you have to see if you can switch to the Reese Sidewinder 5th Wheel King Pin with Rotating Turret # RP34FR. The easiest way is to try and locate a sticker or placard somewhere on the pin box itself with an identifying mark, or you can call the trailer manufacturer with your VIN. If that information is not available for some reason, you are going to need to take some measurements to determine exactly what you have. I have...

  • How to Determine Correct Sidewinder Replacement Pin Box
    To find the correct Sidewinder what you will need to know is the manufacturer and model number of the pin box on your fifth wheel and match that with the correct replacement, however, the correct part is likely the Sidewinder # RP34FR. This will replace Lippert 0719, 1621 and 1621HD, Fabex 663 and 665, M&M 663 and 665, along with Lippert 1716, 1116, and 0115 pin boxes. The Lippert 1716, 1116, and 0115 pin boxes do require the Spacer Kit # RP97FR. The pin box number should be on a sticker...

  • Recommended Rotating Turret Replacement Pin Box for Lippert 1116
    I have a solution for you, but the Reese Sidewinder 5th Wheel King Pin # RP34FR is not a fit for your Lippert 1116 model pin box. The Reese Sidewinder 5th Wheel King Pin with Rotating Turret - 20,000 lbs # RP77FR is the correct replacement. You may also need spacer kit # RP97FR to ensure a snug fit.

  • Is There A 5th Wheel Hitch For A 2001 Ford F450 Cab And Chassis Flat Bed?
    The only option for installing a 5th wheel hitch on your 2001 Ford F-450 cab and chassis flat bed is the Reese # RP30054. This is not a custom-fit hitch, nor is one available for your vehicle. This hitch requires it to be installed through a 1/2" steel plate under the deck and the plate must be welded to brackets that are bolted to the truck frame by a qualified professional. This Reese 5th wheel hitch has a gross towing capacity of 30,000 lbs and vertical load limit of 7,500 lbs. I attached...

  • Correct 20K Reese Sidewinder for Lippert 1716 Pin Box
    The correct Reese Sidewinder 5th Wheel King Pin for a Lippert 1716 pin box in 20K is part # RP34FR but you'll also need the Spacer Kit part # RP97FR. The Reese M5 5th Wheel Trailer Hitch for Ford Towing Prep Package part # RP30921 will then be correct for a 2017 Ford F-350 Super Duty with OEM Prep Pkg. You will also need the Sidewinder Wedge Kit for 20,000-lb Reese ELITE, M-Series, or ProSeries Fifth Wheel Trailer Hitches part # RP44FR but that's it.

  • Pin Box Replacement for 2010 Montana that Provides Turning Clearance so Slider Hitch Not Needed
    The Trailair pin box part # LC158777 was not designed to provide additional turning clearance so if you were looking for a pin box replacement solution that would give you more turning clearance you'd need the Sidewinder part # RP34FR which fits the same pin box replacement as the Trailair you mentioned and since it moves the pivot point of the trailer back 22 inches you end up with enough turning clearance to not need to use a slider hitch. Our understanding is that your 2010 Montana...

    Yes. You will need a Wedge Kit, # RP64FR too. Curt is the manufacturer of the Mopar branded 5th wheel trailer hitches. The Mopar M30 5th Wheel Hitch uses a Curt head and base specific for the Ram OEM Prep Package. The 5th wheel hitch head is the same as our part number, # C16590.

  • Will Sidewinder Pin Box Void Warranty on 2020 Jayco Talon 403T
    Since a Sidewinder like the 20K # RP34FR is a pin box replacement it won't void the warranty of your 2020 Jayco Talon 403T. With that being said, we do want to make sure that you get the correct one that fits your 5th wheel. The pin box that you referenced is a direct replacement for the following pin boxes: Fabex 663 and 665 Lippert 0719, 1621 and 1621HD M&M 663 and 665 Lippert 1716, 1116, and 0115 (spacer kit required - # RP97FR) If you have something else please let me know and I'd...

  • Recommended Pin Box Replacement for Lippert 1116 for Use With 2017 Ram Short Bed Truck
    Because you have a short bed on your 2017 Ram, for your Lippert 1116 pin box replacement I recommend the Trailair Air Ride 5th Wheel Pin Box - Lippert 1116 - 21,000 lbs # LC155943 if you want to use a sliding 5th wheel hitch. This will give you a cushioned ride with less jarring and chucking due to the integrated shock absorbing air bag. If you are looking for superior turning clearance, then you will want to use a non-sliding 5th wheel hitch along with a Reese Sidewinder. This will...

  • Towing 5th Wheel Trailer with 2014 Ford F-150 with 5-1/2-Foot Bed
    Thank you for the photo of your new 5th wheel trailer showing its front profile. Very short bed pickups like your 5-1/2-foot bed must use a Sidewinder replacement pin box to have enough turning clearance to avoid cab-to-overhang contact. 6-1/2-foot beds can use a slider type hitch for turning clearance but a 5-1/2-foot bed cannot get by with extenders. You will need to replace the pin box on the trailer with a Sidewinder pin box that extends the pivot point by a full 22-inches and use...

  • Sidewinder Pin Box & 5th Wheel Fixed Hitch for 2016 Ford F-150 with 5-1/2-Foot Bed
    A pickup with a 5-1/2-foot bed cannot use a slider hitch for extra 5th wheel turning clearance. Sliders will work well enough on 6-1/2-foot beds but for a 5-1/2-foot bed you will need to use a fixed (non-sliding type) 5th wheel hitch along with a replacement 5th wheel trailer pin box called a Sidewinder. A Sidewinder replacement pin box bolts right up in place of the existing OEM pin box and provides a full 22-inches of additional turning clearance. Most slider hitches provide 12- to 14-inches...

  • Compatibility of Curt C16044 A-Series 5th Wheel Hitch With Sidewinder for 2019 Ram 3500
    The Curt A-Series 5th wheel hitches like the # C16044 20K version you'd looked at is indeed compatible with rotating pin boxes like the Reese Sidewinder/Revolution or the Lippert Turning Point. The leg kit provided with the hitch is compatible with the Ram OEM puck system installed in the bed of your truck. The exact Sidewinder model you need will depend on which OEM pin box your 5th wheel is equipped with. The bolt pattern is pin box specific, so you'll want to choose the proper replacement...

  • Is The Reese Sidewinder RP34FR Compatible With B&W Patriot 5th Wheel BWRVK3255
    The B&W Patriot 5th Wheel Hitch # BWRVK3255 will work with the Reese Sidewinder # RP34FR, but wedge # SWW-06 is required in order to keep the B&W hitch from pivoting. Keep in mind that the Reese Sidewinder will only work with the following pin boxes: Fabex 663 and 665, Lippert 0719, 1621 and 1621HD, M&M 663 and 665. With the Lippert 1716, 1116, and 0115, a spacer kit is required # RP97FR. You will need to check and see which pin box you have on your trailer and make sure it is compatible...

  • 5th Wheel Hitch And Rotating PinBox For 2018 Ram 2500 With RamBox
    The B and W 5th wheel hitch kits for your truck are sliding, and sliding hitches are not compatible with the RamBox on your 2018 Ram 2500 6-1/2' bed. You will need to install a fixed 5th wheel hitch along with a rotating pinbox so that you can clear the bed rails. I would first install the Reese Quick-Install Custom Outboard Installation Kit w/ Base Rails # RP56009-53 which fits your Ram 6-1/2' bed without the OEM prep package. This will give your bed the industry standard rails for most...

  • Can 2018 Ram 3500 with Ram Box Tow Fifth Wheel Trailer.
    The problem with the Ram Boxes is that they make the bed rails so narrow that you can't make turns with a fifth wheel trailer even if you are using a Goose Box. Normally we have to recommend people use a Sidewinder pin box replacement as it's the only pin box that pivots higher and prevents interference with the Ram Boxes. Since you are installing a Goose Box that means you'd have most likely the Lippert 1621 style pin box and the Sidewinder you'd need is part # RP34FR or you have the...

    The factory puck system is not an aftermarket option so there is no way to obtain one on your 2019 Ram 3500, and there isn't an underbed option, but you can still add a 5th wheel hitch to your truck. You will need above-bed rails to do so, and since you have the RamBoxes, a Sidewinder is required as well in order to obtain the needed clearance so the pin box does not hit the RamBoxes. For a 5th wheel hitch you'll need one compatible with a Sidewinder, and for a hitch and base rails I recommend...
