Is that a 3 inch by 4 inch or 3 inch by 5 inch?

@Jim The # DX89FR actuator is designed to be top mounted on a 3" wide tongue. So this could work with a 3" x 3", 3" x 4" or a 3" x 5" tongue depending on your application.

I'm using a tie-down actuator LP80, but are there any actuators that can be installed on it without any modifications?

@Syo We have replacements for the LP80 like the Dexter # DX89FR which doesn't require much modification provided the LP80 is bolted on not welded. You may have to drill an additional hole in the tongue but that would be it. The holes are 3" apart on center.

@JesseM Thank you for your help. I found another eTrailer response recommending the Dexter DX89FR as a replacement for the LP80 with only one additional mounting hole required. Based on the photos I sent, would the DX89FR be a better fit than the Demco DM8669113 for my Ranger trailer? Which option would require the least modification?

@Syo Yes, the Dexter # DX89FR is definitely what I recommend. Its a solid unit and will require the least amount of modification.

The bearing #LM67048 and #15123 that you referenced have the same inner diameter which means they fit the same spindle and the disc brake kit #K2HR526DKG would fit in place of what you have now.

I recommend replacing your current surge brake coupler using either using the Demco Hydraulic Brake Actuator for Disc #DM8104311 or Drum #DM8102511 brakes. I prefer these couplers as they have a Zinc finish which best resists corrosion.

The Kodiak 12" Hub-and-Rotor Assembly #KHR12D that you referenced requires an inner bearing of #25580 and an outer bearing of #15123. For a set of brake pads you would want the part #K225CP.
