Question:
I just purchased a 21 ram 3500 with a 6.4 bed with ram boxes, I have a Curt A16 non-sliding fifth wheel hitch. I’m adding the sidewinder pin box to the fifth wheel camper. I just need to know which rail kit do I need for my ram pick up for no drill. Thank you !

Hey Nathan! For a rail kit you can use the Curt Custom Fifth Wheel Installation Kit for Ram # C16430-104. This comes with a glossy black finish. If you would rather have a carbide finish, # C16430-204 is also available. Both of these mount to existing holes in your vehicle's frame so no frame drilling is required.
