The difference between the two Firestone air bag systems for your 2018 Ford Transit T350 comes down to the # F53ZR is designed for passenger vehicle versions of the T350 where the # F2603 is designed for a cargo van version of the T350. You will want to choose the one that your vehicle falls under to determine which one is the correct air bag system since there will be slight differences to the frames on these vehicles.
