Sidewinder Fifth Wheel Pin Box Coupler with Turret, Hardware, King Pin by 5th Airborne - ST300-SW16K

Sidewinder is the premium fifth wheel pin box coupler designed specifically for short-bed pickups. Its worry-free turning design allows you to make up to 90-degree turns without exiting the truck, throwing a switch or even pushing a button!

Features:

Replaces existing pin box on fifth wheel trailer
Make 90-degree turns without getting out of your truck, throwing a switch or pushing a button
- No fifth wheel slider needed
Designed specifically for short-bed pickups
- Refer to the formula below to ensure proper clearance
Length of Sidewinder arm: 22"
The Sidewinder moves the trailer's pivot position an additional 20" to the rear of the fifth wheel hitch attachment point
- Make 90-degree turns without getting out of your truck, throwing a switch or pushing a button
  - No fifth wheel slider needed
- No contact between truck cab and coach
- Trailer tracks more closely to the truck for better driveability
- Full use of truck bed space
- Easy hookup or disconnect at any angle
- Faster steering wheel response, easier to reverse
C-channel design provides more stability and strength than standard pin box design
- Able to support heavier loads

Specs:

Designed for use with Venture CJ13515 and CJ13517 pin boxes
Capacity: 16,000 lbs; CSA approved
3-Year limited warranty
Made in the USA

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.

Sidewinder premium fifth wheel pin box coupler

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

Sidewinder premium fifth wheel pin box coupler eliminates need for wide turns

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
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.

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.

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.
