Reese Fifth Wheel King Pin - RP61420

This premium fifth-wheel pin box coupler replaces your trailer's king pin for worry-free turning with short-bed pickups. Now you can make up to 90-degree turns without having to exit the truck, throw a switch or push a button.


  • 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
  • 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


  • 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 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 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


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

The Sidewinder

Sidewinder Diagram
  1. The pivot point sits 22" behind the king pin.
  2. The rotating turret attaches to the pin box on your trailer to provide the new pivot point.
  3. The reversible, adjustable king pin locking wedge (not pictured) prevents pivot at the 5th-wheel hitch.
  4. The king pin connects to the 5th-wheel trailer hitch in your truck bed.
  5. The arm is rated at 16,000 lbs.

Up to 90-Degree Turning

90 Degree Turns with 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

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

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).

  • PullRite SuperGlide 5th-wheel trailer hitch
  • Reese Trail Boss 5th-wheel trailer hitch

    Video Transcript for Reese Sidewinder with Rotating Turret Installation

    Today on this fifth wheel camper, we'll be removing the old pin box and installing a new turret and Sidewinder from Reese, product number RP61420. As we said earlier, before we can install our new turret, we have to remove the old pin box. To do that, we'll remove these four bolts on both sides. However, we also have to remove this breakaway switch and trailer wiring before we can remove the pin box. Bolts simply unscrew from their current positions. With all of our electrical components removed, we can remove our four fasteners.

    As you can see, we've already removed two fasteners for now. We're going to use a pallet and a fork truck to take it away from the pin box so it's safer to remove the final fasteners. In this case, we'll be using a pry bar to help with the removing of the pin box. With that removed, we will lower the pallet and proceed to assembling the turret. First thing to do is remove the wedge from the bottom of the Sidewinder.

    It will line up here with the king pin where we'll tighten it down into position later so there will be no lateral movement with our Sidewinder. Before we set up the turret into the Sidewinder, we're going to take some of the white lithium grease or a spray lubricant. Just hit the top of the Sidewinder just to make it easier to slide our turret on. Once that's in place, we'll install the plastic disc, then well set our top plate and bolt it on. We'll be installing the four 5/8 bolts and lock washers.

    With all fasteners installed finger tight, I'm going to use a ratchet to tighten them down, then I'll torque them to specifications as indicated in the instructions. Now that all components are properly installed we can install the turret and Sidewinder into our camper using out truck and pallet. To install the turret, we'll be using these bolts with the flat washers on the outside and the conical tooth washer and nut on the inside. Once those are in place, we'll tighten them down. We will lower the pallet, then torque the specifications.

    Next, we'll reinstall our electrical box and breakaway switch. Now that the Sidewinder is installed, the next thing we need to do is hook up the truck to the camper and tighten our wedge near the king pin. We have the wedge tight enough so that it cannot be moved by hand but we'll still be able to use a mallet. Now, we'll back up our vehicle into place and lock down the king pin. We will have to take a mallet to knock the wedge into position. We'll first snug down the bolt we can reach that will hold the wedge in position, while we pull the truck away and tighten down the other bolt. Now, we can torque the bolts to specifications. With that, our Sidewinder is ready to go. We'll hook the truck back up and take it for a test spin to see how it works. As you can see, when it turns, the turret is doing all the turning while the Sidewinder stays in a stationary position due to the wedge. And there you have it for the Reese Turret and Sidewinder installed on our 5th Wheel camper, product number RP61420.

    I ordered my RP61420 sidewinder on 5/8/17 around 4pm and received it on 5/12/17 at 2pm in good condition and complete. ( FREE SHIPPING ) We installed it on 5/13/17 following all instructions included with the sidewinder ( VERY SIMPLE ) I put it on a 2004 - 286 cougar 5th wheel trailer, being pulled by a 2010 F-150 King Ranch ( super cab) with a 5.7 short bed box. The sidewinder allows me to make a 90 degree turn, ONLY when truck and trailer are on PERFECTLY level ground and then, I only have about a 2 inch clearance between back of cab and front of trailer. Before the sidewinder my turns were very limited. The sidewinder is very well built and rated at 16000 lbs. All of the questions and answers with ( JARED P.) were very helpful to find what I needed with my problem of clearance between truck cab and trailer. It is TRICKY to hook up to with the wedge that locks into the 5th wheel hitch, but I think its worth it when able to make sharper turns in traffic. The Reese Sidewinder with with Rotating Turret is also hooked into a Reese 5th wheel hitch. Great products Reese, Leo C. 381609

    The items were packaged well and did not have a scratch on anything. All hardware was included. I am impressed how wel this unit is built. It is built with much heavier metal than the stock pin box that came off, which is reassuring to me. I was able to install this using a table, some blocks and a floor jack without additional help, but it would probably be quicker if additional help were available. This will definitely give me peace of mind when traveling and make it one less thing to worry about when turning/backing. Great product and service. 187953


    The Sidewinder is working great. The short turning radius is a plus in addition to peace of mind that it wont be hitting the cab of the truck if I have to make a sharp turn. Im glad I got this instead of the sliding hitch.

    Had it installed at dealer when picked up 5th wheel I had it assembled. Had to take it off and redo it. It takes two people or a platform to rest it on. It's not like a regular pin you have to be dead on in backing and something aggravating but it does work good. Have gotten also a 90 degree turn with this 399111

    The "wedge" block that changes the pivot point on the fifth wheel it makes the camper very difficult to hook up to unless you back in at the exact same position as when you unhitched. Even still it does not allow the jaws to close completed without repeatedly trying. This is not a product I would recommend. 258254

    • Minimum Truck Bed Length for Towing a 5th Wheel Trailer Without Cab and Loft Clearance Issues
    • The minimum bed length for towing a fifth-wheel trailer with a standard fifth-wheel hitch, see link, is 8 feet. A 6-1/2 inch bed like the Silverado Extended Cab you mentioned can be used along with a slider style fifth-wheel hitch, see link, that requires you to remember to get out of the truck and move a handle to slide the hitch rearward when tight parking and campground situations are encountered. Once ready to go back out on the road the hitch will need to be moved forward, requiring...

    • Differences Between a Reese Sidewinder and Revolution on a 5th Wheel Trailer and 2012 Ford F-150
    • A Sidewinder and a Revolution are the same thing. It is called a Revolution when it comes as OEM equipment on a trailer. That is the only difference. To determine if the Revolution offers enough extra clearance for your truck and trailer, there are some measurements to look at. First, measure from the center of the hitch jaws to the back of the truck cab and add 22 inches (length of Revolution extension). Then, measure the width of the trailer overhang and divide by 2 to get half. If...

When we add the Rambox feature we also add another complication: reduced side-to-side clearance. Hitch makers like Reese, Curt and B&W discourage use of 5th wheels in such trucks; that said, there are those that have satisfactorily installed 5th wheels anyway. The best solution for the turning clearance problem in such trucks...

    • It is actually required that you use a sidewinder pin box on your fifth wheel trailer if your truck has a bed shorter than 6 feet like your 2012 Chevrolet Silverado Crew Cab because a sidewinder pin box provides the most possible clearance to safely execute sharp turns. To use the sidewinder with your truck you would just need to add a fixed fifth wheel hitch, base rails and brackets. Since you have a 5 foot 8 inch bed, I assume you have a 1500 Crew Cab model.

This will have a negative impact on steering, braking, the head lights will point up. Also, the truck can carry the most weight directly above the rear axle. It cannot carry what it is capable of if the weight is centered...

    • Can Revolution/Sidewinder Pin Box be Used with B&W Companion Hitch that Fits in Gooseneck Ball Hole
    • No, a Sidewinder or Revolution pin box cannot be used with a B&W Companion hitch that fits in the gooseneck ball hole. The problem is that the pivot point on the trailer is locked out at the hitch and moved back 22 inches to the turret on the Revolution/Sidewinder. This creates extra stress and torque on the hitch. This extra force can end up twisting the hitch, and where it connects in the gooseneck ball hole, and can damage both. If it was the Companion hitch that fits in the...

    • Compatibility Of Reese Revoltion/Sidewinder Pin Box with Curt Q16 Fifth Wheel Hitch
    • At one time, the Curt Q16 fifth wheel hitches weren't compatible with the Reese Sidewinder/Revolution, but now that Curt has developed a wedge that's compatible, part # C16992, it's perfectly acceptable to use the Curt Q16 hitch, like part # C16120. The wedge isn't compatible with the Q20 or Q24 fifth wheel hitches, so it's not recommended to use either of those in conjunction with the Revolution/Sidewinder. A Reese Revolution/Sidewinder wouldn't normally be used with a sliding hitch,...

    • Fifth Wheel Hitch For Extra Clearance with 5-1/2 foot bed Truck with Sidewinder
    • 25 inches from the center of the fifth wheel jaws to the cab of a truck is a pretty short distance. When you combine that with a fifth wheel trailer that has a 8 foot wide nose even a Sidewinder can still have a hard time preventing cab/trailer interference. Your best option would be the B and W Patriot Hitch part # BWRVK3200 as the head of this system can be adjusted up to 4 inches back from the cab which would hopefully be enough to allow you to back your trailer up without issue. Use...

    • Is Sidewinder Needed to Tow Fifth Wheel Trailer With 2010 Toyota Tundra Crew Max With 5.5 Foot Bed
    • Since the truck bed is less than 6 feet on your 2010 Toyota Tundra Crew Max 5.5 foot bed, you will need to use a standard fixed fifth wheel hitch and a Sidewinder to give you the necessary clearance between your vehicle and trailer. I am including a link to a FAQ page on information for fitting a Sidewinder to your truck and the clearance formula you can use to determine if it will work with your fifth wheel trailer. To determine the correct Sidewinder for your Toyota Tundra depends...

    • Torque and Grease Specs for Sidewinder Pin Boxes
    • For the swivel arm, the torque should be 150 ft-lbs for the wedge bolts and for the lockout bolts the torque should be 275 ft-lbs (lock out bolts are an optional item). Grade 8 bolts going through outer cap (be sure wear disc is properly lined up) should be torqued to 45 ft-lbs. Pin box torque is as specified in the instructions. A. 1/2 inch Bolts GR5 90 ft-lbs B. 5/8 inch Bolts GR5 150 ft-lbs C. 3/4 inch Bolts GR5 275 ft-lbs I attached a picture that shows the areas of the turret...

    • Is a Reese Revolution or Sidewinder Compatible with a Curt E5 5th Wheel Trailer Hitch
    • There are certain 5th wheel hitches that are not compatible with the Revolution or Sidewinder. The Curt E5 will not be a problem but you will have to keep the hitch locked in the towing position and never slide it back. Doing so will put incredible stress on the trailer and hitch and can cause a lot of damage and it will put the king pin behind the truck axle. This will lighten the front end, maybe enough to adversely affect steering and braking response. If the trailer already has a...

    • Comparing Sliding Hitch vs. Sidewinder for 40-Foot Toy Hauler Towed by 2014 Short-Bed Ram 2500
    • In your application with a roughly 40-foot toy hauler towed by your short-bed Ram 2500 a Sidewinder replacement pin box is the way to go. A sliding 5th wheel hitch like the Curt Q16 # C16521 can give a short bed truck like your 2014 Ram 2500 up to 12-inches of additional turning clearance. On the other hand, a Sidewinder replacement 5th wheel pin box, when used with a fixed 5th wheel hitch, gives you a full 22-inches of additional turning clearance. Sidewinders are made as replacements...

    • Sidewinder Needed to Tow Fifth Wheel with Ford F150 Super Crew with 5.5 Foot Bed
    • The Sidewinder is pin box-specific, not vehicle specific so in order to determine which is needed we will need to know the manufacturer and model number of the OE pin box on your fifth wheel. This information is typically found on a sticker or plate somewhere on the pin box. If you cannot find that information, the manufacturer can usually provide it if you provide them with the VIN of your fifth wheel. You can also take some measurements from your existing pin box as shown in the FAQ article...

    • Best Way to Tow a Fifth Wheel Trailer with 2014 Ford F-150 with 5-1/2 ft Bed
    • For towing fifth wheel trailers with a truck that has a bed length of 5-1/2 feet the best option is the Sidewinder pin box. You will need to remove the pin box of the trailer and replace it with a Sidewinder pin box. Sidewinders are pin box specific so you will first need to know what pin box you have now in order to pick out the correct one. There should be a sticker or a stamping on the OEM pin box of the trailer that will list the pin box number that is on the trailer. Once...

    • Will Reese Sidewinder # ST400-SW01 Fit a Lippert 1621 5th Wheel Trailer Pin Box
    • The Lippert pin box 1621 has a different design and bolt pattern so it requires a different turret than what is on # ST400-SW16K. If the turret you have uses 4 bolts to mount to the arm, then you can just swap the turret for the right one, # RP61300. The only other option would be to replace the entire unit with # RP61420. I have included a video for you to view that shows a typical installation.

    • Longer Pin Box for 5th Wheel Trailer Using a Lippert 1621 Pin Box
    • You could use a Sidewinder pin box, # RP61420 for a 16K, # RP61421 for a 19K, or # RP61422 for a 16K with air ride. When using a Sidewinder you will need to leave the slider locked in the towing position. Sliding it back would no longer be needed since the pivot point will be moved back 22 inches. Any of these will move the pivot point of the trailer back 22 inches. If you lower the tailgate when hooking up the trailer then you also may be interested in a 5th wheel tailgate. I would...

    • 5th Wheel Installation Kit and Hitch Recommendation for a 2010 Toyota Tundra with 5-1/2 Foot Bed
    • Starting with the truck, we do have a semi-custom fifth wheel rail installation kit, # RP30035-309, but this kit is designed to fit the universal installation kit to your 2010 Tundra with a 5-1/2 foot bed and will still require drilling to install the frame brackets. There is not a full custom install kit available for your truck at this time. I attached links to the instructions for the semi-custom kit for you to review. When selecting a fifth-wheel hitch for your truck bed you will...

    • Where to Get Lock Out Bolts for a Reese Sidewinder Pin Box
    • We don't sell the 3/4 x 5-1/2 inch grade 5 bolts needed to lock out a Sidewinder. The only way you will be able to get the correct bolts would be to go to your local hardware store and get them there. This will save you time as you won't have to wait for the bolts to get shipped as they will be readily available at your local hardware store. Take a look at the instructions I have linked on page 6 for more on the lock out feature.

    • Compatibility of Reese Elite Fifth Wheel Hitch with 2015 Ford F250 w/ OEM Tow Prep Package
    • The hitch you mentioned is the same as the Reese Elite, part # RP30142. If you haven't purchased the hitch yet, you might consider getting it from us, as I'm confident our price will be better. The hitch is indeed compatible with the Reese Revolution/Sidewinder pin box. The Sidewinder/Revolution will provide almost twice the extra clearance (22 inches) as a sliding hitch (10-12 inches) would. It'll also eliminate the need to exit the truck to actuate the slider. If you don't already...
