Recommended Sidewinder for an 1116 Pin Box

Question:

I have a Lippert deivise on my fifth wheel and want to change it to a Reece sidewinder which do I buy. I have numbers off of the lippert kingpin . Can some one direct me on what to purchase. Thanks I am want the Reece kingpin a price with shock or with out would be great . I like to get the turn ratio with the Reece sidewinder with the shock or without . I would also need the locking bracket as well so it does not turn on the hitch . The hitch is a BW companion WITH THE FOUR MOUNTS ON THE BED

Thank you so much for the picture and all of the additional information! I spoke with my rep at Lippert and she told me that your 5th wheel trailer has an 1116 pin box and a 19,000 lbs capacity. For an 1116 pin box I recommend the Reese Sidewinder 5th Wheel King Pin with Rotating Turret item # RP77FR. This Sidewinder has a 20,000 lbs capacity.

The Premium Sidewinder with the enclosed air spring is item # RP61412. However, this pinbox only has a 16,000 lbs capacity so you will need to verify your 5th wheel trailer's weight.

To keep the kingpin from rotating inside your B&W Companion Hitch item # BWRVK3300, you will want the Sidewinder Wedge Kit for B&W Fifth Wheel Trailer Hitches item # SWW-06. This wedge will work with both Sidewinders.

To find the turn ration you will need to take a measurement from the center of your king pin to the your F-350's cab and the width of your trailer in inches divided by 2. I have included the clearance formula and directions below. The math will be the same for both of the Sidewinders.

(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
