Truck Repair spicer front axle

Whats the difference between a 12k steer axle and a 13200 steer axle? Is it just one has 2 leafs and the 13200 has 3? Or is there more to it than that, perhaps stronger spindles, beefier axle all the way across?

the axle is different all the way across. Steel density, leaf springs, bearings, spindles. The look similar but they are different.
