Can I Replace a UFP A-70 Surge Brake Actuator w/ the Replacement Inner Member for Dexter DX7.5L?

Question:

Hi there. I have a 2006 IMF boat trailer with a UFP A-70 surge brake actuator. This is a tandem axle trailer with disc brakes. From what I can tell, the difference between the A-60 and the A-70 is the A-70 has a GVWR of 7,000 pounds versus 6,000 for the A-60. Will the DX99FR work for my application? I assume the pin placements for the sleeve are the same for the A-70 vs. A-60 but would love to confirm before I order. Thank you!

Thanks for the pictures Brian. Yes, you are correct the Replacement Inner Member for Dexter DX7.5L Actuator item # DX99FR will replace your UFP A-70 surge brake actuator.

The A-"number" was for the weight capacity of the coupler; an A-60 was rated for 6K and an A-70 was rated for 7K. In the recent past Dexter consolidated everything to be rated for 7.5K so this swap will work and fit.

What kind of boat do you have?
