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 (19K = 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" + 22" = 58". If your fifth wheel trailer is 102" wide, take half (51"), then plug in: 58" - 51" = 7" of clearance.

1. Sidewinder Pivot Point - 22" 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

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 22" away from the cab.

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.
