Reese Sidewinder Replacement For A MORryde Cushioned Pin Box RPB72-1116

Question:

Will the Reese sidewinder replace a MORryde mod RPB72-1116 ? I have a BW Companion 5th wheel hitch regular, no gooseneck

Hey Gordon,

For a MORryde pin box with an 1116 bolt pattern you would need the Reese Sidewinder # RP77FR. I'm guessing you have a B&W Companion OEM and a puck system in your truck bed? For a B&W hitch you'll also need wedge kit # SWW-06 to lock the king pin of the Sidewinder into the jaws of the hitch.

This wedge kit will replace the universal one that's included with the Sidewinder and better fit the funnel of the hitch for more even pressure.

Thank you Kevin, I am a little confused though. I called directly and was advised part number RP85FR. Please let me know which is correct.

@Gordon The # RP77FR would be the correct fit for an 1116 bolt pattern. I'm sorry you were told different, but you can 100% confirm the bolt pattern by measuring the bolt spacing. With an 1116 bolt pattern there should be an 8-3/4" spacing horizontally from center to center of the bolts, 2-1/2" spacing vertically, and 22-3/8" from the rear bolts to the center of the king pin.
