    • Relieves stress on coach frame
    • Reduces vibration inside coach, protecting its contents

  • 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 663 and 665
    • Lippert 0719, 1621 and 1621HD
    • M&M 663 and 665
  • 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.

5th Airborne Premium 5th Wheel Air Ride King Pin w/ Sidewinder and Turret - 16,000 lbs - RP61422

Average Customer Rating:  4.5 out of 5 stars   (90 Customer Reviews)

5th Airborne Sidewinder replaces your fifth-wheel trailer's king pin and alters the pivot point of your rig, enabling you to make up to 90-degree turns. Enclosed air spring in pin box absorbs shock and adjusts for a smooth ride.

by:

Had the flexair pin box on a slider. I hated having to stop get out and slide the hitch back just to make a sharp turn. So I decided to go with the Airborne Sidewinder. So far it I has been a great hitch and I’m very pleased with its performance. Now I can make better than 90 degree turns anytime anywhere.



by:

At this time I’m going to give it 3 stars. It was damaged in shipping. etrailer is great and they said it won’t hurt anything. I’m going to put it on and give it a go and maybe come back and edit the review

I apologize for the shipping damage. I am glad that customer service has taken care of you.

am happy with my new pinbox. Installation was very easy with some help, fit perfectly. I had to run a die nut over 2 trunion bolts that were damaged during shipping. I haven't tried towing yet, but so far I am pleased with my purchase. I have enclosed some pictures of my installation.



by:

This has turned out to be a great hitch. I have had no problems with it at all, I needed to be able to hitch it up at an angle and this is the only hitch I found that allowed that. The only problem I had is that the manufacturer should either leave the airbag valve pushed into the unit or better packaging around the valve for shipping, mine arrived smashed. E trailer sent me a new valve assembly for the air bag. Thanks E trailer.


Comments
David, thank you for your review. In the future if you ever need to replace the valve again the part is # 58382

The King Pin system is working fantastic. I have no complaints at all about it. I have only good things to say about it.
David O - 05/08/2019


by:

The pin box greatly increases the maneuverability of the trailer / truck combination by moving the pivot point back under the front of the trailer rather than in the middle of the hitch in the truck bed. Additionally, the air ride greatly smooths the bumps out on the road and reduces chucking when braking or accelerating. The only reason for not giving 5 stars is that you MUST be perfectly aligned with the pin box in order to attach it to the hitch. Unlike a traditional king pin, this one is modified to have a large steel plate behind it to force the pin box to pivot under the trailer. This means you MUST be perfectly aligned with the pin box to get it to connect to the trailer. Normally, this is not an issue if you are able to back or pull the trailer to the point where the pin box is straight with respect to the trailer. however, often spots require backing in but are not deep enough to straighten the pin box to the trailer. This means that the truck must be backed in at what ever angle the pin box is at to get it to engage in the hitch.



by:

I purchase this Airborne/Sidewinder King pin almost 1 year ago.
When I received the unit the box was in rough shape. inside was a plastic bag that was torn apart ( during shipping ) I think. Inside where only half the bolts that I was supposed to receive. I contacted Etrailer and they said the bolts were on back order but they would request 4 bolts from Reese.. I received them 2 months ago more than 6 months after my request.. I has since bought the 4 bolts I needed last summer. After I installed the unit I put the required air pressure in and got a large popping sound that was 1 of my missing bolts that was bound up inside the unit.. I'm still short 3 bolts and hope they're not inside the unit as well.. I rated this 1 above poor only because the Side winder feature on this is great... It makes a groaning noise I don't like when doing tight maneuvering but the care free turning is great! The Airborne portion of this king pin has done zero for my bucking issue and I still wonder if that's because there's still a bolt jammed in the suspension part of the king pin... My experience with Etrailer has always been excellent and that really hasn't changed, because I think these issues were out of their hands.. I spoke to Reese twice and got no help what so ever....



by:

The product is great but due to me not totally understanding how it works our desire to make 90-degree turns with my short bed F-150 did not work out but it is of no fault of the product. The ride was greatly improved over the old fixed part we had on our RV so I am 100 % pleased with the product, craftsmanship and quality. E-
Trailer provided a great price as well so the overall rating will be a 5+


Comments
In order to execute a successful 90 degree turn using the sidewinder part # RP61422 on a short bed truck the clearance formula must be taken into account. Measure the distance from the center of the 5th wheel hitch jaw to truck cab in inches. Add that measurement to the length of the sidewinder arm part RP61422 is 22 inches. Measure the width of your trailer and divide that number by two. Subtract the trailer width divided in half by the original number the distance from the center of 5th wheel to cab + 22. That is your clearance.

Excellent service and total knowledge of their products.
They always followup to make sure there customers are happy. So rare these days



by:

Great product! I've now used this with a Ford short bed and my new Dodge crew cab short bed.



by:

The service & delivery was great. The 5th Airborne works very well allowing me to get in & out of tight places. I didn't give it an excellent rating for a couple of reasons. One of the nuts had a weld bead in the threads which resulted in a cross-threaded bolt had to use a tap & die to correct. Also, the decal on one side is upside down which I would like a replacement decal as it reflects on the quality of the product, see picture.



by:

Just received, opened and checked for damage. Came with out any, but not really well done. The pin box looks to be just what I needed, well built and smaller than you might think looking at it in a picture. I added this to the model specific rail mounts for the '14 ram that is the new tow vehicle. etrailer has been great through the whole process. Delivered as promised fast and all the bits and pieces there. Very pleased.



by:

Stacey was very helpful. worked through every question i had. payment was super easy and delivery was faster than i expected.

Outstanding !!!! i will be back!!



by:

I have just installed the in box but have not had a chance to pull the camper with it. It will be a new experience.



by:

I installed this on my 2010 Cougar 26SAB. I am towing the 5th wheel with a 2010 Dodge Ram Crew Cab with a 5'7" bed. This is exactly what I need! I can easily turn 90 deg. without worrying about cab impacts. One note: make sure you keep the 4 bolts torqued properly at the pivot point. I check the torque before every tow. Great product!



by:

The unit is heavy so it took 3 to 4 guys to lift it but other than that the product works as advertised

Great customer service and product. All communication courteous and very professional. Thank you.

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


I would have left 5 stars, but the package arrived just about destroyed and the pin box was significantly scratched and the air valve was bent and had to be replaced which I did myself. I had to touch up the paint on the frame of my trailer from the old pin box, so i also touched up all the scratches from shipping.
The hitch is absolutely awesome and was exactly what I was looking for to absorb some road shock! Just got back from a 1,700 mile trip and although it took some experimenting along the way to get it just right, it was worth it. Probably going to add a compressor and wireless valve to control the pressure in the cab because weight and air temps require different psi's. When we left Chicago it was 30° and by the time we got to southern Arkansas, it was 75° and had to let the air out 3 times. On our way back, had to add air multiple times.

I will have our Customer Service team reach out to you. You have already done what I would have suggested which would be to touch up the affected areas with a rust resistant paint.

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


Installed this in 10 minutes. Super Easy to install, you can do it by yourself if you're strong and have some skills. Having a helping hand doesn't hurt though. Although the custom bed isn't done on my truck, it's time for vacation. I used a new B&W turnover ball and companion 5th wheel hitch and connected my newly (easily) installed Airborn air bagged pin box.... rides like a dream!!!!! I shouldn't have used my other non-air ride pin box for 10 years! This pic shows my test run, usually the car is a boat.

DarrenI see you have a flatbed installed on your truck. What issues did you have with height and length of bed? What brand bed and size of bed did you use? I will need to do the same thing to my f350. Tx. Dennis

Hi Dennis, This is a slightly unique emphasis on slightly truckbed combo. First of all its a 5500, not a 3500. 1 ton and smaller Ram, Ford, Chevy all have a 56 CA cab axle, the commercial versions 450

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


I didn’t give a rating yet because it depends on the outcome of this order. I received the pinbox I ordered, installed it, but it was damaged. The airline and fitting was broken off of the airbag. If my order gets replaced with a new pinbox, I will be satisfied.

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


I really like my new King Pin with airbag and sidewinder and turret. I am not the greatest at backing up but I feel I have better control due to the geometry change. It is much easier to make sharp 90 degree turns. I hated to have to stop and move the slider. I have had to reset the four bolts on top of the turret and the two bolts holding the wedge to 150 pounds. I use a white lithium spray to ensure an easier connection. I am still trying to figure out what pressure I should set the airbag though. I have it set between 60 and 65. The ride is very smooth with very little chucking.

I absolutely love this turreted kingpin and airbag
