Reese Fifth Wheel King Pin - RP61452

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.


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: Venture CJ20517, CJ13515 and CJ13517
    • Also fits Dexter pin boxes: 221-0033-00 and 221-0031-00
  • 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.


King Pin Locking Wedge Locations for Specific Hitches

5th Airborne Sidewinder Locking Wedges

1. Draw-Tite, Hidden Hitch and Reese (15K, 16K and 20K Select Series); Husky; Owens; Valley; and similar units

2. Reese Signature Series, Elite Series and similar units

3. Holland and similar units


A. Bolt locations

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 5th-wheel trailer hitch
  • 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 longer than a week, the air springs be drained to relieve pressure on the system.

Ask the Experts about this Reese Fifth Wheel King Pin

Do you have a question about this Fifth Wheel King Pin?


  • 5th Airborne Sidewinder and Warranty on Trailer
  • In terms of warranty for the king pin, the 5th Airborne Sidewinders do have their own 3-year warranty. As for frame damage, a Sidewinder is not going to cause any damage to the frame so long as you use it with a compatible hitch on your 2018 Ford F-250. Some fifth wheel hitches are not compatible with a Sidewinder because the pivot point gets changed to the Sidewinder's turret, but if you have the right fifth wheel hitch there is no reason to be concerned that your trailer's frame will...

  • Solution for Sidewinder Pin Box that Doesnt Straighten Out Totally When Towed Behind Truck
  • When we hear about the situation you described where the Sidewinder doesn't straighten totally out as it's being towed behind the truck and there is noise around corners the issue is that the wedge isn't the correct one for the hitch being used or it's not properly installed. What fifth wheel hitch does your customer have? Do you know which wedge they are using? Ideally you use a custom wedge like the # SWW-06 which is designed for the jaws of a B and W hitch.

  • 5th Wheel Hitch Recommendation for 2017 Ram 3500 Short-Box with Factory 5th Wheel Rail Kit
  • The best slider hitch for your 2017 Ram 3500 short-box that has the factory 5th wheel rail kit is without a doubt the B&W Companion # BWRVK3670. This 20K-rated hitch drops directly into your factory pucks and its slider gives you a full foot of travel for low-speed maneuvers. B&W fabricates and assembles their hitches not too far from us, in Humboldt, KS, and their products are renowned for their excellent design and better-than-it-needs-to-be build quality.

  • Can a Sidewinder Pin Box be Used with a Sliding 5th Wheel Trailer Hitch on a 2008 Dodge Ram
  • To use a Sidewinder pin box with a slider 5th wheel trailer hitch you just have to make sure that the slider stays locked in the towing position at all times. Do not slide it back when using the Sidewinder. Doing so will put extra stress on the truck and trailer. Also, some 5th wheel trailer hitches cannot be used with a Sidewinder. I have linked a help article that covers this for you.

  • Sidewinder 5th Wheel Pin Box Availability For a Venture 20513 Pin Box
  • At this time the only Sidewinder pin boxes that we have to replace a Venture pin box are the standard Sidewinder, part # RP61450, and the 5th Airborne Air Ride Sidewinder, part # RP61452. These pin boxes are designed to replace the Venture CJ13515 and CJ13517 pin boxes. You can measure your existing pin box to determine if one these pin boxes, or another, will work on your trailer. We have an article that details how to measure and it has a chart the will allow you to compare your measurements...

  • Will a B and W Companion Hitch Work with a Sidewinder Pin Box Replacement
  • If the B and W Companion hitch is one like the # BWRVK3600 that attaches using the 4 pucks it will work with a Sidewinder. If the Companion hitch is like the # BWRVK3500 which only attaches with the center post for the gooseneck hitch it can't be used with a Sidewinder due to the torque the Sidewinder would put on the attachment point. You will want to use the proper wedge, part # SWW-06, with the Sidewinder. I attached a help article on Sidewinders for you to check out as well.

The custom wedge you want is the Sidewinder Wedge for Curt A16 and A20 5th Wheel Trailer Hitches # C16992.

  • Can a 5th Wheel Trailer Hitch be Installed in a 2015 RAM 3500 Short Bed with Rambox
  • I can set the record straight for you. No manufactures fit the Ram trucks that have the Rambox feature. The issue is the bed is more narrow and the trailer pin box will hit the sides of the bed when you turn. Some customers have used a Sidewinder pin box in place of the regular pin box on the trailer. This moves the pivot point of the trailer back 22 inches. We have been told by customers this works. However, none of the manufacturers have tested this to confirm. Customers would start...

  • Is There a Reese Elite Airborne Sidewinder To Replace A 10K Revolution Pin Box?
  • To know what will fit your trailer, you will first need to determine the bolt pattern on your trailer pin box. Some Revolution models cannot be replaced according to my contact at Reese and others can. To determine your fit, I've attached an article to help get the correct bolt pattern for your pin box so we can determine if there is a replacement for your application or not.

I have included a link to the installation details for you to view. I have also included links to an FAQ on 5th Airborne units and to Sidewinders for you.

  • Can a Sidewinder Pin Box be Rotated By Hand and 5th Wheel Hitch for 2015 Chevy Silverado 3500
  • A Sidewinder pin box would be very difficult to move by hand. It is designed that way on purpose because if it was easy to move that could increase the likelihood of trailer sway. As far as the angle you would have the same limitations using a Sidewinder as you would with any pin box. To compensate for awkward angles a hitch that has a full floating head (can move freely in any direction, not just side to side and front to back) would be the best hitch to use. If you choose to go...

The 5th Airborne Sidewinder pin box that corresponds to your original is part # RP61452. This pin box is rated for 16K trailers and is a direct bolt-on installation.

  • Recommended 5th Wheel Hitch, Slider for 2015 Dodge Ram Pickup with Rambox
  • Officially our 5th wheel hitch suppliers do not recommend any 5th wheel hitch installation in Dodge Ram pickups that have the Rambox system due to the reduced bed width. We have, however, heard reports of successful installations in the 2014 Rambox-equipped trucks using a Sidewinder replacement pin box. The Sidewinder moves the pivot point back 22-inches behind the king pin which keeps the body of the pin box stationary within the limited available width of the Rambox bed. This configuration...

  • What is the Torque Rating for the Turret Bolts on My 2007 5th Airborne Sidewinder?
  • I was able to track down a copy of the instructions for your 2007 5th Airborne Sidewinder with the 3 turret bolts.The 3 bolts need to be torqued at 80 ft./lb. per the instructions. Keep in mind that you are not torquing the bolts as one would when clamping something together,but torquing to retain the 2 pieces. My contact at Reese explained that the lock washers and bolts may need to be replaced over time and they recommend checking the torque after each use. He said that Reese also recommends...

  • Is a Sidewinder Pin Box Compatible With a B&W Turnoverball Gooseneck Hitch?
  • To use any Sidewinder pin box like # RP61452, you will not be able to keep your B&W Turnoverball Gooseneck hitch because it is not made for the torque when turning required for that system. No adapter will solve this. However, there is still a way to allow you to tow a gooseneck trailer using a 5th wheel rail kit. You have a couple options. If you want to keep a clean bed, then you can use the Under-Bed Rail and Installation Kit for Reese Elite Series 5th Wheel Trailer Hitches # RP30074...

  • Replacement King Pin for MORryde RPB72-2210031
  • There is an upgraded king pin which will greatly improve your ride available as a replacement for your MORryde, though not a Trailair. From my research, your MORryde RPB72-2210031 was a replacement for Dexter pin box 221-0031-00 and the upgrade replacement which fits is the 5th Airborne Premium # RP61452 from Reese. This is similar to the Trailair in that it greatly reduces the amount of chucking and jarring you'll experience when towing, and uses an air bag to help deliver a smoother...

  • How to Determine if a Sidewinder from One 5th Wheel Trailer Will Fit on a Different Trailer
  • To determine if there is a Sidewinder and/or 5th Airborne Sidewinder for the new trailer I will need to know the manufacturer and model number of the pin box itself. This information should be on a sticker or plate on the pin box. On most 5th wheel trailers, there are wings that stick out of the overhang that are part of the frame/chassis structure. the pin box bolts to it so on your existing trailer you would want to get the pin box, including the turret that is bolted to those wings...

  • Is Curt Q20 5th Wheel Hitch Compatible with Reese 5th Airborne Premium 5th Wheel Air Ride King Pin
  • I do have a solution for you but unfortunately the Curt Q20 hitch head is not compatible with a pin box that has a rotating turret like the Reese 5th Airborne Premium 5th Wheel Air Ride King Pin. This is due to the spherical axial bearing that allows the hitch head to easily pivot. Instead I recommend using the Curt A20 5th Wheel Trailer Hitch # C16140 and selling your Q20 to help offset the cost. The A20 is very similar to the Q20 but it has a fully articulating torsion head instead...

It would take me longer so I would allow more time unless you have installed these before. When you order the Elite Series fifth-wheel hitch # RP30871, you will need to order for the 8 foot bed to get this option for use with the Fifth Airborne.
