Adjusting the Wedge on a Sidewinder/Revolution Pin Box For a Curt E16 5th Wheel Hitch

Question:

I have the universal wedge almost touching the king pinless than 1/8inch 1/16inch ?from touching itand there still seems to be a little sideways movement of the pinbox over the hitch plateshould I move the wedge up until it touches the king pin itself? Or is there always going to be a little movement on the hitch plate? my hitch is the Curt E16 hitch is mounted on a 2012 Ford F350 SB 5th wheel is a 2013 Flagstaff 8528IKWS thanks

When installing a wedge for a Sidewinder, it is important to make sure the wedge is making contact with the opening of the fifth wheel head. Check out the photo I attached showing how the universal wedge should fit in a head. Keep in mind, this is a universal wedge, so there may be a small gap, even if the wedge is all the way against the king pin.

For a better fit, I recommend using the Custom Wedge for the Curt E16 Fifth Wheel Hitch, # RP64FR. This wedge was designed to fit the Curt E16 hitch that you have and will likely work better than the universal wedge.

Do they make a wedge that goes on a Reese sidewinder that will fit th Patriot 16 K that I bought from you guys? The wedge I have now is a universal type.
