Air Bag & Compressor for 2020 Ford F-350 Super Duty Dually 4WD Towing 5th Wheel Trailer


Planning for springtime updates/upgrades. Need your opinions. 2020 F350 CC DRW. Would like to add air suspension/bags and onboard air possible horn, filling tires. What systems do you suggest? 5th wheel is a 2019 Chaparral 391QSMB. Want to replace bearings on axels preventative - trailer is new to us. Also, what should we consider / look at for brake wear/replacement?

Ok, let's go ahead and start with the air bags for your 2020 Ford F-350 dually (which I'm assuming is a 4WD), and the best option that is both compatible with your dually and 5th wheel hitch is the Firestone Ride-Rite Air Helper Springs # F35FV.

These Firestone air bags - which are only compatible with 4WD models - are absolutely the best because they are the most well-constructed air bags available. The Ride-Rite air bags are made with four layers of reinforced rubber, which is a thicker, more reliable construction than other air bags which have just two rubber layers on other air bags. The quality of their build means not only are they going to provide your F-350 with the best support, they are also the most dependable air bags you can get.

During the installation of these air bags, you are going to want to ensure your air lines are cut perfectly straight, and the best way to do this is by using the Air Hose Cutter # AL10530, and for a compressor, since you are looking to inflate more than just the air bags you will need the Air Lift QuickShot Compressor System for Air Springs - Support Line and Reserve Tank # AL25690.

For the brakes, what you can look for is if the pads on the shoes are cracked, or for magnets if you can see the copper windings coming through. The other thing to do is just a road test, and you should be able to tell if the braking is struggling to halt your trailer. In regards to bearings, you will need to take apart your current hub assembly and look at the bearings themselves; wipe away the grease and you should be able to see the part number stamped directly on them.

I have added a number of links below for you to check out, for video reviews, our selections of bearings and brakes, as well as some help articles you may find useful.
