Question:
What is the base part number for a BandD companion hitch the one being sold is for a Ram for a 2020 GMC 2500 AT4 standard bed 6.9ft? I would like to keep the head and just need the cost of the base, if possible. Thx- Eric

Hey Eric. Congrats on the new truck! To replace the base on a B&W Companion item # BWRVK3670 that fits the Ram puck system you'll need one of the following parts:
GM Factory Puck System Compatible Sliding Base - Replacement Slider Base item # BWRVB3775
GM Factory Puck System Compatible Standard Base - Replacement Base item # BWRVB3715
Both of these bases will only fit the GM factory puck system on a 2020 GMC Sierra 2500.
Just to confirm. Does your 2020 GMC Sierra 2500 have the factory puck system?
