SBA is Set Back Axle. SFA is Set Forward Axle. I don't think its brand specific. Anyone can have it. Seems as though most vocational trucks utilize it though. The difference is due to weight distribution laws per state. Both configurations are made so that companies can comply if they like a particular truck. For example....you love the 49x. Well if John Doe trucking company like the 49x in NY but also has a company in California, both states could have different requirements so one may need the SBA and the other SFA.Cemail Cebeci wrote: ↑09 May 2021 13:43 I will ask you what is the difference between SB SF SBA SFA and which brands and models they use most
Now I am just stating examples for California and New York as I don't know. So take this with a grain of salt.
