Replacement for TDE LP85 Surge Brake Actuator  

Updated 07/16/2024 | Published 07/15/2024



Question:

I was wondering if you have a surge brake actuator coupler that will easily replace a Tie Down LP85 coupler? Thank you, Chris

Hi Chris; I believe the LP85 was integrated into the tongue of the trailer. Unfortunately, that means it won't be an easy swap to replace it since other actuators won't fit inside the trailer tongue and line up with the holes from your old actuator.

The Dexter DX7.5L A-60 Brake Actuator w Electric Lockout # DX93FR you looked at will work as a replacement as long as a 7,500 lb capacity is high enough for your trailer. This is designed for disc brakes which I believe you have since the LP85 was also designed for disc brakes. It has a weld-on installation and fits a 3" x 5" straight tongue. You could also use the # DX89FR which bolts onto a 3" wide tongue.

I haven't run into the LP85 before but on similar models customers reported a tongue width greater than 3" since it was designed to house the actuator. If that is true for you your best option would be to have a local shop cut off the old tongue and weld on a standard tongue in its place.

Thank you!!! I did find that our dealer can order a replacement LP85 so maybe that is the brought I will go… the other consideration is the Dexter electric over hydraulic unit. But it’s twice the price. Thank you again!!!
