- Trailer tracks more closely to the truck for better driveability
- Sidewinder-and-turret assembly bolts onto your 5th-wheel trailer pin box

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

- The pivot point sits 22" behind the king pin.
- The rotating turret attaches to the pin box on your trailer to provide the new pivot point.
- The reversible, adjustable king pin locking wedge (not pictured) prevents pivot at the 5th-wheel hitch.
- The king pin connects to the 5th-wheel trailer hitch in your truck bed.
- The arm is rated at 16,000 lbs.
Up to 90-Degree Turning

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.

Do you have a question about this Fifth Wheel King Pin?
- Can a Sidewinder be Used in a 2007-2010 Chevy with 5 foot 8 inch Box Length
- Using a Sidewinder depends on the length of your truck bed, the width of your trailer and the position of the fifth-wheel hitch in the bed of your pickup. Normally the hitch is 1-1/2 inches in front of the center of the rear axle on these models of Chevy pickups. If you measure from 1-1/2 inches in front of the center of the rear axle to the back of the cab and then measure the width of your trailer and divide it by 2 you will be able to see the difference you have for turning clearance between

- Locating Lippert Pin Box Number on a 2003 Montana Mountaineer in order to Choose a Sidewinder

It will not be on a tag or referenced as model number. You definitely want to be sure that you have the correct model number before you order.

- Dificulty Unhooking 5th Wheel Hitch With Two Different Styles of 5th Wheel Hitch
- Since you have had the same problem with two different brands of hitch it sounds to me like the problem may be with the pin box. If the king pin is damaged then this may be the cause of the problem. It could also be that the king pin is at an angle on the trailer. If so then the angle would cause the king pin to bind in the hitch and would cause the problem you are experiencing. I would check the king pin and the coupler in the hitch for signs of damage or wear that would tell you the story of h

- Sidewinder Pin Box Maintenance for a 2007, 32 Foot Everest 5th Wheel Trailer
- To address the issue of the angled arm we will need to check a few things. First of all, your pin weight cannot exceed 3,200 pounds for the 16,000 pound sidewinder so, you will need to check the pin weight of your trailer to be sure you have not overloaded the Sidewinder. If your pin weight is too heavy, you will need to reposition the load in the trailer to lighten the pin weight or upgrade the sidewinder to accommodate the load.

Since you have a Curt Q5 hitch, you cannot use the Sidewinder with the hitch. Curt has a big warning disclaimer about using a Sidewinder with the Q5, not to mention Fifth Gear does not offer a wedge that will fit the Q5.

- Can a Reese Sidewinder with Rotating Coupler be Used with a 5th Wheel to Gooseneck Adapter
- If you need some extra clearance, we do carry several 5th wheel to gooseneck trailer hitch adapters. I recommend the Ranch Hitch Universal 5th-Wheel-to-Gooseneck Coupler Adapter with 8 Inch Offset, # AM3139. This adapter will give you 8 inches more clearance than a standard straight 5th wheel to gooseneck adapter. This unit is also height adjustable from 11-3/4 inches to 14-3/4 inches, and it has a gross trailer weight capacity of 24,000 pounds and vertical pin weight capacity of 6,00 pounds.

- What Can Be Done To Help With Unhooking Fifth Wheel With Sidewinder From Ford F150 Short Bed
- It sounds like the moving parts inside the fifth wheel head on your Reese 16K hitch need to be cleaned with WD-40, which will clean the area but it will not eliminate all the grease. This will help the fifth wheel head work properly. Then apply a light coating of all purpose grease, such as the LubriMatic White Lithium Grease, # L11350, to the skid plate and the jaw of the fifth wheel hitch. This will help reduce any metal to metal squeaking and wear and it will make it easier to unlock the hitc

- If you use a Sidewinder coupler on your 1998 Dodge Ram 2500 4x4 short bed, you will be able to use a regular fixed hitch in your truck bed. With the Sidewinder, the pivot point is moved 22 inches closer to the tailgate. This will create more space between the truck cab and your fifth wheel trailer when making sharp 90 degree turns.

- Which Sidewinder Replacement Pin Box will Work on a 2006 Ford F-350 with a 15K 5th Wheel Hitch

Most king pins will have the pin box number listed on a sticker or stamped on the king pin itself.
