Question:
I have a bad A-75 actuator on my tandem boat trailer, I was looking to replace the inter-slide assembly with the A-60 my understanding is that they are interchangeable. I only have 2 disc brakes and a folding trailer tongue not sure that matters. Can you direct me to the correct part?

Hey Carey, thanks for the information. It sounds like you need the Replacement Inner Member for Dexter DX7.5L Actuator item # DX99FR. The A-"number" was for the weight capacity of the coupler; an A-60 was rated for 6K and an A-75 was rated for 7,500 lbs. In the recent past Dexter consolidated everything to be rated for 7.5K so the item # DX99FR will work and fit.
What kind of boat do you have?
