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 (19.5K = 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. Rotating turret - attaches to the pin box on the trailer and provides the new pivot point 22" behind the king pin, allowing for maximum maneuvering
2. Rear mounted, heavy-duty shock absorber
3. Enclosed air spring - also absorbs shock and is protected from UV exposure and shielded from road hazards
4. Universal king pin locking wedge (not pictured) - reversible and adjustable - prevents pivot at fifth wheel hitch
5. King pin - connects to fifth wheel trailer hitch in truck bed

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.

Hitch Specifics and Wedge Locations
1. Draw-Tite, Hidden Hitch and Reese (15K, 16K and 20K Select Series) Husky, Owens, Valley and similar units
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.
