What is the Difference Between the Curt A20 and Curt Q20 5th Wheel hitch for a 2022 GMC Sierra 3500


I am looking at 5th wheel hitches for my 2022 GMC Sierra 3500 standard bed with the puck system. I noticed there is a Curt A20 and Q20 but didn't notice any major differences. What is the difference between those hitches?


Expert Reply:

The Curt Q20 5th Wheel Trailer Hitch # C16536 and the Curt A20 5th Wheel Trailer Hitch # C16541 do have 2 big differences. I am going to start with some things they have in common. Both hitches use the same Curt R20 Round Tube Slider # C16550 with 12" of travel and have a weight capacity of 20,000 lbs. With either the Q20 or A20 you will need the Adapter Rails for Curt 5th Wheel Hitch # C88KR, this adapter will drop into the pucks in your truck bed to provide the mounting point for either hitch.

The two biggest differences between the Q20 and A20 is the warranty and the head movement. The Q20 has a 10 year limited warranty for the hitch while the A20 has a limited lifetime warranty for the hitch. The Q20 has a 360 degree head movement that uses a spherical axial bearing that allows for easy pivoting of the hitch head while the A20 has a double pivot system. One other difference is while both the A20 and Q20 use dual jaws, the A20's jaws are interlocking.
