Features:

  • 5th-Wheel trailer's pivot point is moved an extra 22" toward the rear of your tow vehicle so that you can easily make 90-degree turns, even with a short-bed pickup truck
    • No need to get out of your truck, throw a switch, push a button or mount a 5th-wheel slider
    • Trailer tracks more closely to the truck for better driveability
  • Fully enclosed, custom-tuned air spring in air ride trailer coupler - cushions and absorbs shock
    • Reduces longitudinal shock (chucking) by nearly 60 percent
    • Decreases vertical shock by 44 percent
    • Relieves stress on coach frame
    • Reduces vibration inside coach, protecting its contents
  • Air bag can be repositioned with 2 easy-to-access screws to better support varying loads
    • Move forward for light tongue weights
    • Move backward for heavy tongue weights
  • Sidewinder-and-turret assembly bolts onto your 5th-wheel trailer pin box
  • King pin connects to standard 5th-wheel trailer hitch and allows easy hookup and disconnect at any angle
  • Included locking wedge prevents king pin from rotating
    • Some 5th-wheel hitches may require custom wedge (sold separately)
  • 1-Piece, streamlined construction
  • C-Channel design of the Sidewinder provides more stability and strength than standard pin box
    • Able to support heavier loads


Specs:

  • Designed for use with the following pin boxes:
    • Fabex 500, 503, 520, 530, 560 and 765
    • Lippert 1116, 1716 and 0115
    • RBW 7019 and 7028
  • Weight capacity: 16,000 lbs
  • Clearance: see formula below to ensure proper clearance
  • 3-Year limited warranty


Clearance Formula

Use the formula below to ensure that there will be enough space between your truck cab and trailer when you are executing a 90-degree turn with the 5th Airborne Sidewinder installed.


(A + B) - C = Clearance

A = Distance from center of 5th-wheel hitch jaw to truck cab in inches

B = Length of Sidewinder arm in inches (22")

C = Width of trailer in inches divided by 2


For example:

If you are using the 16,000-lb 5th Airborne Sidewinder, then B = 22"

If the distance from the center of your hitch to your truck's cab is 36", then A = 36"

And if your fifth-wheel trailer is 102" wide, then C = 51"

102/2 = 51

Therefore,

(36 + 22) - 51 = 7" of clearance


The 5th Airborne Air Ride Coupler with Sidewinder

16K 5th Airborne Sidewinder Diagram
  1. The rotating turret attaches to the pin box on your trailer to provide a new pivot point 22" behind the king pin.
  2. The rear mounted, heavy-duty shock absorber reduces chucking and relieves stress on your trailer frame.
  3. The air spring can be adjusted to provide a smooth ride for both your truck and trailer. Because it is fully enclosed, it's protected from UV exposure and shielded from road hazards.
  4. The reversible, adjustable king pin locking wedge (not pictured) prevents pivot at the 5th-wheel hitch.
  5. The king pin connects to the 5th-wheel trailer hitch in your truck bed.

Up to 90-Degree Turning

90 Degree Turns with 5th Airborne Sidewinder

It is now possible to turn your short-bed truck 90 degrees without having to worry that your trailer will collide with the cab of your truck. The universal king pin locking wedge included with this Sidewinder prevents your trailer from turning or pivoting at the fifth-wheel hitch. Instead, the rotating turret at the end of the Sidewinder allows turning and pivoting to take place an additional 22 inches away from the cab.

3. Holland and similar units

B. King pin


Custom King Pin Locking Wedges: The included universal wedge prevents the king pin from rotating in most fifth-wheel trailer hitches. Certain hitches, however, require a custom wedge (sold separately).


Note: Do not use the 5th Airborne Sidewinder with any of the following:

  • Curt Q5 5th-wheel trailer hitch
  • PullRite SuperGlide 5th-wheel trailer hitch
  • Reese Trail Boss 5th-wheel trailer hitch
  • B&W Companion 5th-wheel trailer hitches that mount in the Turnoverball gooseneck hole
  • Colibert 208BW 5th-wheel trailer hitch
  • Hi-Rise gooseneck-to-5th-wheel adapter by Draw-Tite, Hidden Hitch, Bulldog and Reese
  • Any other gooseneck-to-5th-wheel adapter


Note: It is recommended that if sitting idle for more than a week, the air springs be drained to relieve pressure on the system.

This king pin has been one of the best purchases for hauling my fifth wheel with a short bed ram with ramboxes.


Comments
Ive pulled my 5th wheel about 6,000 miles with the sidewinder. I do seem to have to add air everytime I hook it, but the ride quality is great and the maneuverability has made my purchase hands down the best upgrade I did to my fifth wheel.

This kingpin is awesome! Short bed fifth wheel towing solved. I tow with a Crewmax Tundra and I never worry about hitting the cab. This pin solves the need to have a slider hitch (which are heavy, cumbersome and expensive. I needed to watch my weights as well since I tow with a 1/2 ton. No additional weight with replacing the pin. The ride is great too having the shock absorber and air bag in the pin box. Can't say enough good things about it. Once the wedge is set and aligned properly, you are set. Only negative is you need to drop and hook up straight on. It doesn't work well when dropping/hooking at an angle. I keep a torque wrench and a 5/8" socket with me in case I need to adjust the turret back to the "straight" position.

After having used the 5th Airborne Premium 5th Wheel Air Ride King Pin w/ Sidewinder and Turret for about 7,500 miles (one year of towing for me), I would not recommend this pinbox setup unless it was absolutely necessary for your application. PROs: It does provide a nice ride quality (albeit with the occasional odd popping noise) and provides additional clearance for shortbed trucks (and the ability to pull a fifth wheel with a RamBox equipped Ram Pickup). CONs: Poor quality. The turret is not completely square, it requires consistent maintenance for it to operate smoothly and the directions I received with the packaging was not clear (and did not match the posted online instructions which were more up to date). Also, as with all the recent Reese products I have purchased, the powder coat/paint was damaged on delivery and easily flakes off over time.



- RP61412
by:

I am very happy with this Sidewinder. No more having to slide my hitch in order to get my trailer out of storage. The only trick is making sure you are lined up with the pin box so the wedge engages correctly. You can hook up at any angle by just pushing the pin box so it lines up with your approach angle. It takes a little more time, but it is far easier than using an auto-slider. Once you are hooked up, you no longer have to worry about tight turns or backing into spaces.

This item works as described. Diana in sales was awesome to work with and made sure they had the right parts I needed for my rig after Reese told me what parts I needed for my rig. I can't compare it to other kingpins as I haven't had a 5th wheel in 20 years. I will say that for my rig, this is perfect. I'm pulling with a 2012 Dodge Ram 2500 short bed with the Ram boxes. I called Reese and they told me exactly what parts I needed to order from Diana to set this up correctly for my truck. I can turn tight angles and have no worries at all.

A great purchase. The shock absorber removed virtually all of the chucking. What little that is left is very mild and generally only one bounce.

Excellent product! Nice ride, easy hook up! I almost bought the Pull Rite 12K model 3100. When I saw it weighed 350lbs, I looked for a better solution. The Sidewinder was the answer! No compromise!

Review from a similar Airborne Premium King Pin in Fifth Wheel King Pin


Love this pin box. The air ride provides the smoothest towing ride for our 36ft 5th wheel as well as our Chevy 2500HD High County over this rough spots and rail road tracks. This is our 2nd one as we just sold our last 5th wheel and felt we just had to have this same smooth ride with our newest RV. I’ve got to add that the sales and support by Tara G. Was outstanding, very knowledgeable and super friendly service. Many thx

Review from a similar Airborne Premium King Pin in Fifth Wheel King Pin


I like my airborne fifth wheel air ride coupler. Every thing inside out of the sun clean and neat looking. the best part is when there (some boon docking ) all the draws and cabinets are closed. A bad dip and bump is nearly smoothed out about five miles from home. Not worried about damaging 5th wheel. More relaxed drive. Yes it leaks some no big deal just like checking the tires. glade I did it!

Review from a similar Airborne Premium King Pin in Fifth Wheel King Pin


This Airborne Kingpin box works great! Our hitch location in second-hand truck seems located in less than ideal position. This resulted in lots of "bucking & chucking" but Air-ride has changed it to gentle float at worse. Great product at fair price!

We just recently were able to take the 5th wheel out for a trip after installing the air ride coupler. Our ride was soooo much better, no more jerking in the cab and things bouncing round in the trailer. So glad that we made the purchase.

Review from a similar Airborne Premium King Pin in Fifth Wheel King Pin


I had a Fabex 5th airborne hitch pin on my other 5th wheel and was very pleased. Bought new 5th wheel and put on Reese 5th airborne hitch pin expecting the same performance, but the Reese does not perform as well as the old one. I have tried different air pressure and different air bag positions but cannot not find the smoothness I had with the old one. Also, I have had to touch up paint because of rust causing the paint to chip and come loose in certain areas. Just wish I could give it a better review.


Comments
I am sorry to say that I am not happy with this product. Although it is only one year old the paint has faded and it looks much older. I continue to touch up, have tried waxing it but believe at some point I will have to replace with another brand or re- paint. Guess I just got a bad one.

I bought the Reese fifth wheel king pin for a upgrade to the factory one. It was easy to install. What a big difference it made. After some adjustments, as per the instructions, no more chugging or very little. Now enjoy traveling with the Fifth wheel.

Still enjoying the Reese fifth wheel kingpin. When we are done for the season I let the air out of the airbag and refill in the spring. Has a little bit of surface rust on it. Will sand and paint. Still a great product.

Review from a similar Airborne Premium King Pin in Fifth Wheel King Pin


This pin box made a tremendous difference in my fifth wheel trailer. With the original pin box, the trailer controlled the truck and now it is the other way around. Now instead of huge jerks on rough roads, I get cushioned bumps. I can look in the rear view mirror and see the pin box absorbing the bumps.

After a year, I still love this product. The best improvement I have made on my 5er.

Review from a similar Airborne Premium King Pin in Fifth Wheel King Pin


The air valve stem would not accept air. Replaced the valve core to correct the problem. Fiberglass fairing on LongHorn 5th wheel would not fit new king pin box as it is longer that the original one. Just finished about 3500 miles with this new King Pin box, finding the ride somewhat improved, especially on rough freeway often found going through big cities. Did installation myself by first pushing box onto hitch, then using truck positioning and trailer jacks, was able to get box into correct position. Later repeated the exercise to lower the box one row of bolt holes to better match original king pin height.

Review from a similar Airborne Premium King Pin in Fifth Wheel King Pin


Air fill valve was damaged in shipment ( as mentioned in many reviews). Etrailer had mfg send a new one overnight. I suggest that you ship with the fill valve not installed, having the customer install it when attaching to 5th wheel. Mfg sticker specifies that the attaching bolts be torqued to 200 ft. Lbs. Had to rent a torque wrench to install, thanks to my nephew, he was able to to apply enough pressure to achieve that setting. Hard for an old retired person to exert that much force. Now the good stuff. We traveled from California to New York. By the time we got there, my back was in bad shape due to the severe chucking. Ordered the pin box to be delivered to one of our Campground stops. We're now half way home, and my back is not hurting at all. Chucking is gone, great product!

  • Do Sidewinder Pin Boxes Help Towing With Long Bed Trucks as Well as Short Bed Truck
    Sidewinders give the most benefit to short bed trucks since they allow turning clearance without needing a slider hitch but they also provide other benefits that all truck bed lengths will benefit from. The trailer will track better behind the truck as you make tight turns. This means that the trailer won't take quite as much of a "shortcut" as you make tight turns since the pivot point is further back. And Sidewinders make reversing the trailer easier too. In my (and many others) Sidewinders...

  • Would Sidewinder/5th Airborne part # RP61412 Have Capacity for 15.5k 5th Wheel Trailer
    Yes, the Sidewinder/5th Airborne part # RP61412 that you referenced will have the capacity you need and would work well. Your trailer at it's max weight capacity would weigh less than what the Sidewinder is rated for so as long as you stay under the weight capacity of your trailer you would be just fine.

  • How to Choose Correct Reese Sidewinder without Pin Box Number
    In order to choose a compatible Reese Sidewinder like the 5th Airborne # RP61412, you will need to determine what kind of pin box you have. Since you are unable to read the label with the pin box number on your existing 2010 Jayco Eagle Lite, you can use the bolt hole measurements of your pin box to determine which one you have. I have attached a helpful FAQ that explains how to do this. Once you have determined which pin box you have, you can then go to the separate article I attached...

  • 5th Wheel Towing with 2014 Ram 2500 with Rambox
    For a Ram short-bed truck with the Rambox feature the best bet for 5th wheeling is a Sidewinder pivoting pin box that replaces your standard fixed pin box. This will extend the truck/trailer pivot point toward the trailer by 22-inches. The wedge that you will use to lock the king pin in the hitch will keep the pin box straight so that the trailer actually pivots at the rear of the Sidewinder. You will select the wedge made for your specific hitch. We have several Sidewinder models that...

  • Does Sidewinder Pin Box Affect Where Pin Weight is Carried on Truck and Trailer

  • Does Sidewinder Pin Box Fit Fifth Wheel Trailer With Non-Removable Pin Box
    Sidewinders require very specific fit applications on trailers. Basically you have to be able to remove the pin box on the trailer and it has to be a standard style of pin box so that you can pick out the correct one to fit in its place. There isn't a universal way to attach them to a trailer and if you have to cut your old one off to remove it that's a strong indicator that there isn't a way to install a Sidewinder on it.
