Video Transcript for Reese Spacer Kit for Rotating Turrets Review

Today, we're going to take a look at and show you how to install the Reese Rotating Turret for the 5th Airborne and Sidewinder 5th Wheel Kingpins. Now, when we use this with part number RP61301, which is the spacer kit, it's an exact replacement for the ST100 rotating turret. In that configuration, it'll fit the Fabex 500, 503, 520, 530, 560, and 765, as well as the Lippert 1116, 1716, 0115, and the RBW7019, and 7028. Now, here's what our turret's going to look like. We're just going to be replacing the existing turret that was on our customer's Airborne Sidewinder here. Basically, what has happened is he's switched to a different camper and this doesn't give him the width we need, so we need to go with one just a little bit wider to make up that spacing.

Nice thing about it, we have several different turrets available. In this case, if like this customer, if you are switching campers, we can just simply get a new turret to put on there to fill up that gap. We don't have to buying the whole Sidewinder kit again. These work really well with the Sidewinder or with the 5th Airborne Sidewinder kits. They're just a replacement. Here, we've got four bolts that we're going to remove.

We have already added on one of our side plates here. Once we have it installed, we'll show you how to add the other one on. It's really straightforward, really simple. With the side plates that we've got here, part number RP61301, this is actually going to turn our turret right into that ST100 that was previously offered. This'll sit right here on the side.

We'll show you how that goes on in a minute. Let's get the turret installed on the Sidewinder. We want to remove the four existing bolts right here on the top. Hang on to them, because we're going to be reusing them. Lift that plate up.

With the plate should come our ring. Our turret kit's going to come with a new ring, so we won't need to hang onto that. Keep that for backup. Grab both sides of the turret, lift straight up on it. See there it's going to slide right off. We'll set this aside. The new turret is going to slide right down on it. This cutout here should be facing toward our truck. We're going to place our ring right down on top. See, that's going to allow it to spin freely there. Our top plate's going to come down on, then we'll snug those bolts down and torque them to the specifications that we'll find in our instructions. Now, for our side plates, simply take the roll pins that are provided. We want the notched side to be facing downward. We'll line up the small holes, see we've got two here in the side plate. There's going to be two in the side of the turret. I'm just going to set our side plates down on a flat surface. Use the roll pins and a hammer, and we'll just tap these in. Once we've got them started there, line them up with out turret. Then, we can just simply knock them on in. We want to make sure those roll pins are flush with the outside edge here. As we slide this in place, our pin box is going to slide down the outside. If those pins we're sticking out at all, they're going to cause it to hang up on us. Let's go ahead, head out and get it installed on the camper. Depending on which pin box we're going into, or which set of brackets we're going into, that's going to vary which hole location that we'll be using now. We're doing the Lippert 1716, so we're going to use hole pattern or configuration B, which is going to be the low hole closer to the middle on the bottom, then the hole closest to the middle on the top. You can see I just used a little white paint marker, kind of marked them. That way, when we get it up in place we'll be able to kind of identify those. We'll be looking through the side plate, so we want to be able to identify that we've got those lined up. Now, let's go ahead and stick it up in there. Now that we've got our holes lined up, we'll take our bolt, we're going to take our provided hardware with the flat washer. Slide it through from the outside. Then, on the backside, we'll have a conical tooth washer. The teeth of that need to face outward towards the side plate. Then, we've got a hex nut that we'll put on there as well. Now, we'll just go through and snug down each one of our bolts, then we can torque them to specification. Now we've mounted our breakaway switch and our junction box back up into place. We're going to keep them mounted on the part that's attached to the camper itself. That way we don't have to worry about our wires being stretched too much. Remember, it's going to pivot here now instead of here on the front. We don't want to attach that stuff up here, because then it's going to be flexing that wire in and out all the time as it turns. With everything back in place and re-secure, that's going to complete today's installation of the Rotating Turret for the 5th Airborne and Sidewinder 5th Wheel Kingpins.

Average Customer Rating:  4.7 out of 5 stars   (12 Customer Reviews)

Kit is required for use with Sidewinder rotating turret RP61300 if the pin box on your trailer measures 12-1/2". Pin boxes that meet this criteria include Fabex 500, 503, 520, 530, 560 and 765; Lippert 0115, 1116 and 1716; and RBW 7019 and 7028.

- RP61301

Adequate quality. Had one large burr that had to be filed off before installation. Used to adapt Goosebox to Lippert #1716. I realize that is made to fit many applications, but they really missed an opportunity to strengthen the connection. Recommended position is the lower bolt pattern, but the adapter plate could have been made taller and tied into all nine holes, making the whole assembly stronger. Same for the Goosebox. It just begs for the center two holes on each side to be drilled though and have 12 bolts instead of 8. Just like the OEM mount was. 814716

Best decision I have made! 802389

Plates work well and fit into the gap between the Lippert factory box and the Reese Goosebox. The crush pins could be easier to install but overall it worked well. 749014

  • How to Determine Which Reese Goose Box Replaces Lippert Pin Box
    The Reese Goose Box Air Ride Coupler Adapters are going to replace the Lippert pin box on your Fifth Wheel so the hole spacing on the brackets is pin box specific. Your existing Pin box should have a sticker on it that tells you the Lippert OEM pin box number. Common Lippert pin boxes are 1621, 1621HD, and 1716 so you would want to choose a Goose Box that fits the bolt hole spacing of your particular pin box. If you are not able to find a sticker then you will need to measure the bolt...

  • Is a Spacer kit Needed for Sidewinder Rotating Turret?
    You have the correct Rotating Turret # RP61300 for your Lippert 1716 pin box; if it is too narrow you are correct that you would need Spacer Kit # RP61301, which mounts on the side of the turret and should be used with pin boxes that measure 12-1/2". I've added a link to a review video of this kit for you as well.

    The correct air bags for your 2005 Ford F-350 2WD are the Firestone Ride-Rite Air Helper Springs part # F2398. Then add the Air Lift QuickShot Compressor System for Air Springs - Support Line and Reserve Tank part # AL25572 to fulfill your needs. As far as the 7.5" measurement you are asking about it is in fact the measurement from the center of the ball to the leading edge of the pin box.

  • B&W Gooseneck Hitch to Replace OEM Gooseneck Hitch on a 2016 Ram 3500
    You can replace the OEM puck system on your 2016 Ram 3500 with the B&W Turnoverball Underbed Gooseneck Trailer Hitch # BWGNRK1314 but you will need to use the installation hardware that comes with the B&W kit. Not only have these bolts been tested and approved with the B&W gooseneck hitch but typically hitch hardware, whether it is for bumper pull or 5th wheel/gooseneck hitches, is only meant to be torqued once. The reason that other gooseneck hitches don't have an offset is because they...

  • Reese Goose Box for 2017 Fuzion Toy Hauler with MorRyde RPB72-1116 Pin Box
    For the Reese Goose Box that will work perfectly to replace the existing MorRyde RPB72-1116 model on your Fuzion Toy Hauler I recommend the Reese # RP94720 along with the Spacer Kit # RP61301 (which is what allows it to fit the Lippert 1116 wing brackets).

    Yes, the Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter # RP94720 can replace your existing 1116 pin box on your Keystone Fusion if the Spacer Kit # RP61301 is used. Since your Fusion is rated at 17K the # RP94720 will be perfect, it's rated at 20K GTW and 4K TW. For a goose ball and safety chain kit I recommend B&W Ball and Safety Chain Kit # BWGNXA2061.

    On your 2011 Open Range 375BHS with 14, 140 GVWR, the 16,000 lb Reese Goosebox will work well. The 20,000 lb option is not necessary. If you have the number 1621 on your pin box, then you will use the Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter # RP94720. If you have the pin box number 1716, 0115, or 1116 then you will use the same Goose Box, but you will also need the spacer # RP61301.

It also completely removes one of the other factors that could be coming into play, which is a hitch with a loose jaw system or a worn-down king pin.
