Question:
I have an aluminum utility trailer by royal cargo trailers inc. It has 3500 lb axles and the hub measures to 2 and 5/8 between holes. I am looking for a left side drum and electric brake assembly.

Hey Scott, 2-5/8" between holes means it has the common 5 on 4-1/2" bolt pattern.
Looks like you were checking out the Easy Grease Trailer Hub and Drum Assembly 3,500lbs 10" (5 on 4-1/2") # AKHD-545-35-EZ-K, which is spot on what you need for your aluminum utility trailer with 3,500lb axles and hubs. Then you can use the left side electric brakes etrailer Electric Trailer Brakes - Self-Adjusting - 10" 3.5K # AKEBRK-35L-SA.
It's typically best to install both sides of electric brakes at the same time, instead of just one side. If you wish to go this route, you can use this electric brake kit: # AKEBRK-35-SA.
