5th Airborne sidewinder replaces your 5th-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.
Features:
Specs:
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
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" away from the cab.

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

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.

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 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.

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.
Review from a similar Airborne King Pin in Fifth Wheel King Pin
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.
Review from a similar Airborne King Pin in Fifth Wheel King Pin
This hitch is great, no more chucking and it also takes the hard bounce out. Would recommend to anyone. You will need to adjust the pressure in the air bag to suit the weight of your pin. 100% better pull, you wont be sorry.
Review from a similar Airborne King Pin in Fifth Wheel King Pin
I have a 40 foot, 16,000 GVWR fifth wheel towed by a 1 ton, SRW, long bed with Timbrens also purchased from etrailer. The FW came with a Rotaflex kingpin. The kingpin did a good job with chucking, but the overall ride was very rough. I decided to go with the Reese Fifth Airborne. We went on a 250 mile trip just before installation of the Reese Fifth Airborne. My wife likes to knit while riding. There were stretches of the interstate where she would have to stop because the ride was so rough. We happened to go over the same stretch of road after the installation of the Reese Fifth Airborne. She did not have to stop her knitting once. The road doesn't turn smooth as glass with this kingpin, but the jarring is eliminated and turned into a a smooth, more subtle bounce. There are similar products on the market and other setups that are greatly more expensive. IMO, the Reese Fifth Airborne works very well, is relatively affordable and doesn't detract from the looks of the FW. And, of course, purchasing from etrailer is great.
Edward K - 05/01/2021Review from a similar Airborne King Pin in Fifth Wheel King Pin
Unit arrived in good condition. Was a breeze to install, about a 1 hour job with 2 people including removal of old Tri-Glide. Didn't like the "banging" back and forth with the tri-glide. The only issue I had was having to drill pilot hole for breakaway switch screw. Non issue! Can't wait to make a haul with it. Alaska here we come!
ROY J - 05/03/2018Review from a similar Airborne King Pin in Fifth Wheel King Pin
I've had my Elite Airborne Sidewinder for about 6 months now. it's mounted on a 33 ft Jayco and pulled by a 2016 F-150 Lariat with a 5.5 ft box and the Max tow package. Total trailer weight is about 7800 lbs empty and closer to 9-9500 when we are loaded. We have done several short trips (under 200 miles) and one longer one so far from Montreal to Charleston, SC. I'm nothing short of blown away by this coupler. There is no chucking, and it pulls so smooth you'd hardly think there was a trailer back there. Even my wife has commented that it hardly feels like we're towing. The sidewinder allows 90 degree turns easily and I can back it down a 80 ft driveway easily. I check the air once in a while in the air ride and have yet to check the key but I can back on to it easily. This coupler does exactly what it was advertised to do, and does it extremely well. We've had it out 6 times this year already and have a few more in mind before calling it a season. My thanks to Reese for an amazing coupler and to Pat and etrailer for their help in getting it to me so fast! Great customer service!

Wow...what a difference! Replaced our pin box with the 5th Airboure and the ride immediately improved. Almost no chucking! Even my wife noticed how nice and smooth the truck now rides.
Review from a similar Airborne King Pin in Fifth Wheel King Pin
The 5th Airborne Air Ride Coupler is very well made with quality welds. Installing on a 2010 Cyclone 3612 Toy Hauler, I did have to cut about 1/2 inch from the fiberglass at the top front of the Lippert Trailer Mount. This modification provided the 3/8" vertical movement required to allow the front 3 bolt holes to line up. Other than the small fiberglass trim, a very clean installation.
Review from a similar Airborne King Pin in Fifth Wheel King Pin
Received my 5th Airborne pin box in 3 days. I didn’t have any help readily available and I couldn’t wait. It was a direct replacement of my old pin box. The guy I was emailing was very helpful and helped me correct my order as I ordered the wrong one and caught my mistake before it processed. He was great to work with as erailer always is. Highly recommend these guys for all your trailering needs. It was a little aggravating to install alone with some makeshift braces and 2 large screwdrivers to line up holes. Be sure to sand the inside of the frame if any rust or anomalies are present. Other than that, was a simple install and fit as it should. Thank You etrailer!
Review from a similar Airborne King Pin in Fifth Wheel King Pin
I haven't used the air ride pin box yet, but I will be going on a trip this weekend. Installation was a breeze with the help of my son to place in position. It took about 45 min. to remove the old pin box and install the Airborne. Another 30 min. to secure the electrics and trailer emergency brake switch.
Review from a similar Airborne King Pin in Fifth Wheel King Pin
This item arrived quickly. There was some rust inside of the mounting cavity that had to be removed before installing the 5th Airborne. You may also experience some swelling from the manufacturer welding up the pin box cavity. Once this is cleaned up, installation is easy.
Review from a similar Airborne King Pin in Fifth Wheel King Pin
Was looking for a fifth wheel trailer porpoising solution and this helped considerably. It took some time to figure out the right air pressure to put on king pin and air lifts I have on truck to find the right combination. Although I miss the chuck free Motoryde feel, I’ll take a slight chucking vs. my trailer coming apart from bouncing up and down. Much cheaper and convenient solution to others I have seen.

Dana at etrailer was the best, order shipped same day and I received it within two days. Installation of the 5th Airborne was very easy and a well built product.

Review from a similar Airborne King Pin in Fifth Wheel King Pin
I contacted etrailer several times trying to figure out how to fix my problem. Everyone there that I spoke with was very knowledgeable and helpful. They shipped the product right away and I received it a day before expected. I can't say enough about the great people at etrailer. I would definitely recommend them to anyone looking for trailer parts.
Review from a similar Airborne King Pin in Fifth Wheel King Pin
I love the Air Ride King Pin with Sidewinder. The air cushion has removed the lag when taking off and stopping as well as smoothing out the trailer movement on rough road. The solid construction has served me well on our recent 2000-mile road trip. I tow a 12,000 lb fifth wheel with a short bed 3/4 ton truck.
Review from a similar Airborne King Pin in Fifth Wheel King Pin
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.
Review from a similar Airborne King Pin in Fifth Wheel King Pin
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.
