  • 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

Therefore,

(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 19,000 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

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).

  • 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

Video Transcript for Reese Fifth Wheel King Pin - Pin Box Upgrade - RP61421 Review

Speaker 1: Today, we're going to take a look at the Reece Sidewinder 5th Wheel King Pin with the Rotating Turret, and has a 19,000 pound weight capacity.With this Sidewinder, the fifth-wheel trailer's pivot point is going to move an extra 22 inches toward the rear of your tow vehicle so that you can easily make 90 degree turns, even with a short-bed truck, so there's no need to get out of your truck, throw a switch, push a button, or mount a fifth-wheel slider. Your trailer will even track more closely to the truck for better drivability. The 22 inches is measured from the center of the king pin right up here, to the center of the turret post.This Sidewinder and turret assembly will bolt onto your fifth-wheel trailer. Does come with the mounting hardware to install it. The king pin right down here is what will connect to your standard fifth-wheel trailer hitch, and allows for easy hookup and disconnect at any angle. This does include a universal locking wedge that'll prevent the king pin right here from rotating in your hitch jaws.

Now some fifth-wheel hitches may require a custom wedge, and we do sell those separately on our website.This is all a nice, one piece, streamlined construction. The Sidewinder itself has a nice C-Channel design which provides more stability and strength than your standard pin box, and it's able to support heavier loads.Few specs on this. The turret right here, this is designed for use with the following pin boxes. It'll fit on the Fabex 663 and 665; fits on the Lippert 0719, 1621 and 1621HD; and it'll also work on the M&M 663 and 665. Trailer weight capacity on this is 19,000 pounds.

The pin weight capacity is 3,800 pounds.One thing I do want to mention is, if you'll use, on the product page of this product, if there's a, at the bottom of the page, there is a clearance formula that you can use. That'll let you calculate if there's going to be enough space between your truck cab and your trailer when you're executing a 90 degree turn with the Sidewinder installed.Again, here's where your turret will turn. Your king pin right up here is what'll be connected to your fifth-wheel hitch.That should do it for the review on the Reece Sidewinder 5th Wheel King Pin with the Rotating Turret and a 19,000 pound weight capacity.

Great Hitch. I have a 42 ft 16k Fifthwheel pulling with a Ram 3500 Mega Cab Short Bed with a RamBox. Great Combo. No concern with bed or cab strike. 711234

by:

This is the way to go. The sidewinder allows me to get 90 degrees to the 5th wheel with plenty of clearance with the cab. I have a F350 with 6-1/2’ box. It does require precise alignment when hooking up but it’s not much of a problem after practice. I had a slider hitch and this beats that hands down. Towing is great also and the hook up solid, I highly recommended this for short bed application after using it for 8,000 miles of towing. 710847

Product arrived quickly and in good condition. The box was trashed and heavily taped. Maybe better packaging from the manufacturer is in order. etrailer's video for install was excellent and easier to follow than the paper instructions. I would definitely buy from etrailer.com again 505876

Ask the Experts about this Reese Fifth Wheel King Pin

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


  • Base Rails and Fifth Wheel Hitch for 2013 Ford F-150 With 5-1/2 Foot Bed
  • Yes, the Reese Quick-Install Custom Bracket Kit # RP50081 will fit your 2013 Ford F-150 with a 5-1/2 foot bed; you will need to use Base Rails # RP58058 with this kit. The brackets and rails can also be purchased together at part # RP50081-58. Keep in mind that towing a fifth wheel with a 5-1/2 foot bed will require your trailer have a Sidewinder, and for the fifth wheel hitch you use to be a fixed hitch that is compatible with a Sidewinder. For this I strongly recommend the Reese Select...

  • Recommended Reese Sidewinder Pin Box Compatibility with 5th Wheel Trailer
  • The Sidewinder pin boxes are pin box specific replacements so you will need to know the pin box of your new camper. For instance if it has an extended pin box like the most common Lippert 1621 extended pin box, then you would use the 16K # RP61420 or 19K # RP61421. Some pin boxes have an air ride version as well like the 5th Airborne Premium 5th Wheel Air Ride King Pin w/ Sidewinder and Turret - 16,000 lbs # RP61422. The Sidewinder pin boxes will all move the pivot point of your...

  • Sidewinder Pin Box to Replace a Lippert 1621 to Improve Turning Clearance with 5th Wheel Trailer
  • It sounds like your fifth wheel trailer's pin box is making contact with your 2010 Ford F-150's side rails when you make turns. This is one reason why we recommend at least 6 inches between the underside of the trailer and top of your bed rails. One solution to your problem is a taller fifth wheel hitch but this sometimes can cause your entire setup to not ride level. Another solution, like you suggest may be a Sidewinder pin box. Sidewinders are designed to replace specific pin box...

  • If your 2016 Ram 2500 has the B&W Companion 5th Wheel Trailer Hitch w/ Slider # BWRVK3400-5W and it mounts in the Turnoverball Installation Kit # BWGNRK1384-5W you cannot use a Sidewinder because the single attachment point for the Companion - in the gooseneck of the Turnoverball - creates too much movement and stress on a single point, potentially damaging the equipment or creating an unsafe towing situation. That said, if your 2016 Ram 2500 has the OEM prep package with the and you...

  • Will Sidewinder Allow 2016 Ram 1500 With Rambox to Make 90 Degree Turn?
  • In order to determine if a Sidewinder such as # RP61420 will allow you to perform a 90 degree turn with your 2016 Ram 1500, you first need to measure the distance from the center of your fifth wheel hitch jaw to your truck's Rambox.You will also need to know the width of the trailer you will be pulling. You can then use this formula to find out if you can do a 90 degree turn: (A + B) - C = Clearance A = Distance from center of 5th-wheel hitch jaw to Rambox in inches B = Length of Sidewinder...

  • Recommended Equipment Needed to Tow a 16,000 lb 5th Wheel with a 2016 Diesel Ram 2500
  • To figure out how heavy of a trailer you can tow with your 2016 Dodge Ram 2500 take the GCWR of your Ram (25,300 lbs) and subtract the Curb Weight of your Ram (7,620). This leaves you with 17,680 lbs of weight for any extra things on your truck like a 5th wheel hitch as well as passengers, luggage, your trailer, plus any tanks on your trailer. If the trailer that you are looking at has a dry weight rating of 12,650 lbs then that leaves you with 5,030 lbs for passengers, luggage, 5th...

  • Is the Lippert 1621 an Extended Pin Box
  • The extended notation you have mentioned for the Lippert 1621 5th Wheel Pin Box part # LC1387883 is in regards to the style. This is also know as the "long" style and there are several other pin boxes with this style that have similar dimensions but they are not designed to move the king pin. If you take a look at the attached photo and help article that should then make things a bit more clear. The only way this extended/long style will move the kingpin further out is if you were using...

  • Yes, the B&W Companion OEM 5th Wheel Hitch part # BWRVK3600 will fit your 2018 Ram 3500 with the 6-1/2' bed if you have the factory prep package. However, in order to allow for sufficient turning clearance between the cab of the truck and loft of the trailer during a 90 degree turn you will also need to use a rotating pin box like the Sidewinder 5th Wheel King Pin with Rotating Turret part # RP61421. If you need one of these just let me know which pin box you have on your trailer now (brand/model...

If you have not used a rotating pin box before then the only real difference in regards to operation is that you will need to align the truck as straight as possible when you couple the two together.

  • Fifth Wheel Trailer Hitch for a 2017 Ram 2500 with Rambox
  • Yes, it is possible to tow a 5th wheel trailer with a 2017 Ram 2500 with RamBoxes. However, because of the of the RamBox feature not all 5th wheel products are compatible. In my opinion, I personally would not get the RamBox feature.The boxes will limit your hitch options and what components that are available will increase the over all expense of a 5th wheel hitch for a Ram with RamBoxes installed. I recommend getting the factory prep package without the RamBox. For this application,...

  • Recommended 5th-Wheel Hitch for 2017 Ram 1500 with RamBox
  • I do have a solution for you, however the sliding 5th-wheel hitches we have available are not recommended for use on a 2017 Ram 1500 that has the Rambox like yours. The issue is that the Rambox feature can interfere with a sliding hitch, which is what is typically needed on short bed trucks in order to provide proper clearance during sharp turns. To tow a 5th-wheel trailer with your Ram 1500, I recommend going with a fixed 5th wheel hitch like the Reese Select Plus # RP30081 along with...

  • Recommended 5th Wheel Rails and Hitch for 2018 GMC Sierra 1500 5.5 Bed for Reese Revolution Pin Box
  • A Reese Revolution is the equivalent of the Reese Sidewinder. The Revolution is the factory installed option and the Sidewinder is the very similar aftermarket option. For a 5-1/2 foot bed, a sliding hitch will not work, so the Revolution or Sidewinder route is the only option to provide you with turning clearance. The really good news is that is by far the ideal option even if you had a longer bed truck. For your 2018 GMC Sierra 1500, I recommend you start with the Reese Quick-Install...

  • I am assuming that your 2018 Toyota Tundra 5-1/2 foot bed does not already have any sort of 5th wheel rails so the first thing we ill need to look at is an installation kit. Looking at how the various air bag kits install on your truck it doesn't look like they will interfere with 5th wheel frame brackets so that is good. You can use Demco installation kit # DM8552020-71. This will allow you to place the hitch so that when the trailer is attached the king pin will be centered over the...

  • Your current pin box is a Lippert 1621 on your 2013 Forest River Thunderbolt XLR. There is not an air ride option for the Sidewinder that is over 16K. So with your GVWR of 18,000 lbs, you unfortunately will need to choose between the additional turning clearance of a Sidewinder and an air ride pin box. If you choose the Sidewinder, you will want the 19K # RP61421. If you want the air ride without the additional turning clearance, then I recommend the Trailair Flex Air 5th Wheel...

The only caveat to this is a Q20 is not compatible with a Sidewinder so you would need to go with a very similar hitch, the Curt A20 5th Wheel Trailer Hitch # C16540-16026.

It is not possible to lock out the head with any type of wedge, so there would be two pivot points in the towing setup, which would not work. Because of the shorter bed in your 2019 Ram 3500, you do need...

This combo is actually already available with part # RP61421. This will fit the 1621 model pin box on your new trailer perfectly.

If your original pin box was the Lippert 1621, then the Reese Sidewinder 5th Wheel King Pin 19,000 lbs # RP61421 will fit on your Grand Design Solitude trailer.

If you need more capacity than that you would want the 19k version which is part # RP61421. The third version is an air-ride, cushioned Sidewinder that has a 16k capacity. For that you would want the part # RP61422.

You will want to make sure the truck and hitch have weight capacities that exceed the trailer's loaded weight. Since your Ram 1500 has a short 5-1/2 foot bed, the safest way to tow a trailer is to use a stationary 5th-wheel hitch and replace the pin box on the trailer with a Sidewinder, if it does not have one already. The Sidewinder will be required to...

For example, if your trailer is fitted with a Lippert 1621 or 1621HD pin box you could use Reese Sidewinder # RP61420 for a 16K-rating, part # RP61421 for a 19K rating or part # RP61422 for an air-cushioned 16K Sidewinder.
