Sidewinder Wedge for Curt A Series 5th Wheel Trailer Hitches - C16992

Average Customer Rating:  4.7 out of 5 stars   (58 Customer Reviews)

Bolt this wedge onto your Sidewinder or Revolution pin box to prevent the king pin from rotating in your Curt A Series fifth-wheel trailer hitch.


Although I had to wait 4 months for it to come in and needed this item in order to use the 5th wheel, by the time it arrived the season was over. Now that I have it, it works as it should so I'm happy with the product.


I didnt use this attachment on my 2021 GMC 2500 HD. I do have to be careful backing up but can almost put my truck at 90° to my 5th wheel. I have a 2021 Reflection 268 BH.

This wedge is designed for a sidewinder or revolution pinbox that will lock out the pivoting head of a Curt A Series fifth wheel trailer hitch. You will definitely want to use the wedge so that you do not get two pivoting points but if your pinbox already came with one, you can use that one.

etrailer really knows their stuff! Highly recommend!


I have a curt A16 with a turning point pin box. The wedge fits like a glove. Tip for lining up your wedge with your fifth wheel. Take the fifth wheel head off rest it on your tailgate under your pin box. Put some wood under it to line it up with your pin box or just lower your landing gear. Pull the fifth wheel head on to your pin. Tap your wedge in till it’s snug then just tighten it up.


The wedge worked perfectly. Much better fit than the universal wedge. Easy to install.


Quality looks good.. bought for my sidewinder I just installed to fit my curt A16k 5th wheel.. bolts are too small in diameter to screw into sidewinder provided with the wedge. Sidewinder stock wedge bolts are too short in length bc the wedge bolt cutout channel is too narrow (fit for the smaller screw heads). etrailer customer service is top notch. Haven't had the time to try and call to see what to do. Just wanted to share to those with new sidewinder 20k's, this wedge doesn't work with it. My sidewinder was built Aug. 28 2021.


Very helpful always Get what I need The first time You guys are the best


I will install tomorrow on new 5th wheel. Have not used it yet. Appears to be high quality.

Great. Has worked without fail on a 36ft Rockwood 5th wheel on an A20.

This fits the Lippert turning point hitch and the Curt A16 hitch like a glove no more slop
20 minute install
made of three layers of cold rolled steel welded together not a casting
Made by Curt
Ordered on Thursday arrived before noon on Saturday


Worked perfectly


Received wrong wedge, you then sent a universal wedge but unhappy no updates on proper wedge

Thank you for bringing this to our attention. Our customer service team should be reaching out to you in the near future.

Ordered wedge for turning point kingpin to use with Curt A20. Works much better than kingpin universal wedge.


After purchasing a used fifth wheel with a Reese Sidewinder I had no idea that there were several different wedges based on hitch model. This wedge fit the A16 perfectly and the Sidewinder works as it should.


Awesome support for techs, friendly and courteous, excellent shipping! I highly recommend for RVers.

Very well pleased!
