Thanks for the information Jake! I've got a few options to replace the inner member on Legacy UFP A-607A-75/XR-84 surge brake actuators depending on which one you have. That part number you gave me is actual three different types of UFP actuators.

Which replacement you need is going to depend on how many axles your boat trailer has and if it's a XR-84, A-60, or a 7A-75. I have listed the options below:

Single or Tandem Axle Trailer - Replacement Inner Member Dexter XR84 Actuator item # DX78CR

Triple Axle Trailer - Replacement Inner Member Dexter XR84 Actuator item # DX68CR

The Replacement Inner Member for Dexter DX7.5L Actuator item # DX99FR is going to be the one you need if you have the A-60 or A-75.

These inner members are going to slide into the existing housing attached to your trailer's tongue. This will be a pretty easy swap out because you won't have to remove the housing or drill new holes. They both fit a 2" hitch ball and come with a reverse lockout solenoid. Each of them work with disc brakes only.

What kind of boat do you have and what weight capacity is your trailer rated for?
