Hello Ra, thanks for reaching out. Sounds like you are on the right track here. The Firestone # F2706 is correct for the 2021 Ram 2500 4wd. The problem with this kit is the brackets may not be compatible with some in bed 5th wheel and gooseneck hitches. I wish I could give you a more firm yes or no answer, but you best bet will be to compare the frame of your truck to the diagrams in the instructions and make sure there are no obstructions. You will find the instructions for the # F2706 linked below.

If you find there are obstructions, the Air Lift LoadLifter 5000 Ultimate Air Helper Springs # AL88289 will fit your truck and will be compatible with any in-bed hitch factory or aftermarket.

The # F96VV compressor kit does not come with mounting brackets for the ECU or compressor. They can be installed directly to the frame rail like in the picture below.

Firestone does offer a universal mount for the compressor, part # F2497. I am not seeing that we offer a separate mounting bracket for the ECU, but again the brackets are not a requirement.

I hope this helps. Hit the reply button below and let me know if there is anything else I can do.

Hey Ra, did you have a chance to compare the frame of your Ram to the diagrams in the instructions to check for any obstructions? I'm asking because your experience could help others who are looking to install similar kits.
