Replacement Legs for Curt Q20 5th Wheel Hitch for 2020+ GM Tow/Prep Puck System


I have a new 2021 gmc hd and an old curt q20 from a 17 hd. can i buy new legs and an adapter or just new legs that will fit the new puck spacing? thanks.


Helpful Expert Reply:

The proper replacement legs for your Curt Q20 5th wheel hitch for the model year 2020 and newer GM tow/prep package pucks are part # CU53FR, assuming you have a stationary (non-sliding) hitch. These will bolt into place, replacing your existing legs that fit the previous puck spacing.

If your current hitch is a sliding hitch, you'd need the # C88KR adapter.

I've linked to product description videos for both parts I recommended.
