Customer service matters

The UFP A-75 I ordered became back-ordered by the supplier so they sent an A-60 instead to prevent any further delays, which was much appreciated. The part fit perfectly.

Not Corrosion Resistant

Received the actuator as promised.
This was a replacement for one that engaged accidentally. My fault. However, when I removed the old one, it was well on its way to being too corroded to function. It was 18 months old. I fish salt water and rinse the actuator after every launch. These things have a limited (maybe 3 years) life unless you remove them and Sand and grease the contact surfaces annually. See photos. Only 18 months of use.

Exact replacement

This UPF-75 inner member was an exact replacement for the unit my 1994 Mastercraft trailer. It installed easily. I'm very pleased with the purchase.

Albert W. (Riverside, US)

Excellent service.

David D. (Winchester, US)

This was the exact coupler I needed. Great deal and quick delivery. Was told by a shop that this part was only available as a complete unit. They should have looked here. Who need s the metal outer bracket, this is the part that fails. Saved a bunch of money!

Jim A. (Springfield, US)
Easy to install.

Removal of the old actuator and installation of the new one was not difficult. It did not come with instructions so I watched numerous YouTube videos until I felt comfortable with the bleeding process. I finally found a PDF on the A-75, (Google), and it explained about actuator travel vs brake adjustment. I won't know how it works until next fishing season as I havent road tested it yet.
