MTB Bottom Bracket vs. Normal Bottom Bracket
For threaded 'English' or 'BSA' bottom bracket shells, the standard was 68mm wide for road bikes, 73mm wide for MTB. However, some bikes that are not MTBs use the 73mm wide shell and there are now 100mm wide shells for MTBs as well.

By the way, I looked at the Surly Trucker page you linked to, it says the bike has a 68mm shell not 73mm.

In any case, yes you can fit that bottom bracket. It has a version specifically for 68 and 73mm  threaded shells. On a 68mm shell, two 2.5mm spacers are used so the width of the installed bracket remains the same.

You will need compatible MTB style cranks with the correct length spindle of course. Many folks get tripped up trying to install road cranks with a shorter spindle for 68mm shells into a putative 'road' bike with a 73mm shell.
