Yes. The Curt Q24 5th Wheel Trailer Hitch - Dual Jaw - 24,000 lbs # C16245 and other Curt Q series 5th wheel hitches have a 360 degree axial bearing so it won't allow the pivot point of the Sidewinder pin box to be the only moving component. With another moving part, the Sidewinder will not work as it needs to being firm at the kingpin and only rotate at the turret of the pin box.

If you want a similar hitch that will work with a Sidewinder, I recommend the Reese M5 5th Wheel Trailer Hitch - Single Jaw - 20,000 lbs # RP30928 with Wedge # RP44FR. This setup will work with the Reese Sidewinders and not allow the king pin to rotate inside the hitch.

You want to try to get the center line of the hitch part #BWRVK3600 over the rear axle as much as possible, if not over it then a few inches forward of the rear axle for the best ride quality. On any 5th wheel/gooseneck hitch and vehicle the center…

Curt is the manufacturer of the Mopar branded 5th wheel trailer hitches. For example, the Mopar 5th Wheel Trailer Hitch part 82214742 is the same as the Curt Q20 5th Wheel Trailer Hitch part #C16530-16021 and the Mopar 5th Wheel Trailer Hitch part…

There isn't a wedge that will work with the Q Series of Curt hitches as that hitch is not designed to be used with a Sidewinder. The stress of the Sidewinders ends up damaging the head of the hitch. Instead, you'll want something like…

The main difference between the Curt A25 5th Wheel Trailer Hitch part #C16180 and the Curt Q25 5th Wheel Trailer Hitch part #C16265 is the hitch head. The head on the A25 is far superior to the head on the Q25 because it has an interlocking jaw…

Answer 8

According to Curt the A25 hitch #C16180 is a rebranded Q25 with a head that is made of stronger material. The A25 is the newer version. The changes made to the head address some issues with head failure associated with the Q25. The Q25 was a beefier…

Answer 9

Although Curt recommends the use of black graphite grease with their 5th wheel hitch, you could certainly use the LubriMatic Mini Grease Gun Kit with Multi-Purpose Grease part #L30132 for an alternative option as stated by our Curt representative.

Answer 10

We've checked with Curt and in addition to graphite grease, you can use the LubriMatic Mini Grease Gun w/ Multi-Purpose Grease #L30132 - the added bonus is that this mini-grease gun will fit in most tool boxes and hard to reach spaces.

Answer 11

Curt recommends for the Q24 that you lubricate before each individual use and every 1,000 miles thereafter. Black graphite grease is recommended for the jaw. For a grease gun the part #L30416 would work great since it has a flexible line.

Answer 12

You will not have any problem using lithium grease on your fifth-wheel hitch. Per the instructions for a fifth-wheel hitch, automotive type chassis grease is recommended so lithium grease like part #L11354 should work just fine for you.
