Clearance Formula:
Use the formula below to ensure there will be enough space between your truck cab and trailer when executing a 90-degree turn.

(A + B) - C = Clearance
A= Distance from center of fifth wheel hitch jaw to truck cab
B= Length of Sidewinder arm (16K = 22")
C= Width of trailer divided by 2 (to get half)

For example: If the distance from the center of the hitch to the cab is 36", 36" + 20" = 56". If your fifth wheel trailer is 102" wide, take half (51"), then plug in: 56" - 51" = 5" of clearance.

1. Sidewinder Pivot Point - 20" behind the king pin
2. Rotating Turret - attaches to the pin box on the trailer
3. Universal King Pin Locking Wedge (not pictured) - prevents pivot at fifth wheel hitch
4. Fifth Wheel King Pin - attaches to the hitch in the truck bed for towing
5. Sidewinder Standard Arm - rated at 16K

Nimble and quick. Up to 90-degree turning.
It is now possible to turn the short-bed truck 90 degrees with no fear of contact between the truck's cab and the coach. The included universal king pin locking wedge prevents the trailer from turning/pivoting at the trailer hitch. The rotating turret allows turning/pivoting to take place an additional 20" away from the cab.

Hitch Specifics and Wedge Locations

2. Reese Signature Series and similar units
3. Holland and similar units

A. Bolt locations
B. King pin

Custom Wedges: The included universal wedge works great on preventing the king pin from rotating in most fifth wheel hitches. However, Holland and PullRite hitches will require a custom wedge.

Hitch Problems: The Sidewinder models will work well with all fifth wheel hitches, except for the Curt Q5 and the B&W Companion. The Curt Q5 cushioning allows too much movement for the Sidewinder to operate properly. The B&W hitch requires two additional bolts (1/2", grade 5) to be installed at the rear most support to keep the hitch from rotating. Check with B&W about warranty regulations.

• Can a 2007 Nissan Titan King Cab Tow a 5th Wheel Trailer Using a Sidewinder Pin Box
  
• First, you cannot use a slider hitch when it is in its slid back position with a Sidewinder. If you only had a slider hitch, it would need to remain locked in the tow position at all times. So you should just use a standard hitch if a Sidewinder is needed. 5th Airborne also states that Sidewinders are not compatible with the Pullrite Super Glide. If the hitch has a lower pin weight capacity than the truck, or if the truck is lower, you must go by the lower capacity. You mentioned running t

• To determine the correct Sidewinder for your 91 Jayco Eagle, we will need either the pin box manufacturer name and model number or all of the dimensions for mounting the pin box on the trailer.

• Does using a Sidewinder Change the Hitching and Unhitching Procedure
  
• Because the wedge contacts the funnel of the fifth wheel hitch, you will need to do a good job of having the vehicle lined up with the fifth wheel when hitching up, but other than that, the procedure for hitching and unhitching the trailer will not change. The wedge will remain in place and should not be removed.
