Hey Aiden! The main difference in the Caliber 3" Spool Rollers you were looking at is color and what they're made of. They all fit a 1/2" diameter shaft.
The Caliber 3" Spool Roller for Boat Trailers item # CA52AJ in yellow and item # CA25AJ in blue are both made of PVC. They're going to be more flexible and soft but won't last as long as others made with rubber or TPO.
The Caliber 3" Spool Roller for Boat Trailers item # CA75AJ is made of rubber and is just your standard replacement roller.
The Caliber 3" Spool Roller for Boat Trailers item # CA85AJ is made of TPO and will outlast all of the other rollers previously mentioned.
What kind of boat trailer do you have?
