Question:

I recently ordered TD43FR Swingking and DX56FR Dexter brake actuator however after receiving them today I noticed that they are not compatible as they have the same exact size and neither one can slide over the other for fitting. Please revise and let me know if there is a compatible brake actuator or different swing adapter compatible with the DX56FR actuator

Hey Erick,

The SwingKing Bolt-On Swing Tongue Kit - 3x5 - Black Powder Coat # TD43FR and Dexter Surge Brake Actuator - Disc - Elec Lockout - 2" Ball - Zinc - 7.5K - 3" x 5" # DX56FR are both designed to go over a 3" x 5" tongue, so they are compatible on the same trailer tongue, but the actuator is not able to be installed on the hinge kit, or vice versa.

Instead, you can install the hinge kit on a 3"x5" tongue and then install the actuator on the tongue to make the setup complete. Are you installing this to save space in storage or do you have a different need for the folding tongue?
