Jeff: Hello everybody. This is Jeff at etrailer.com. Today we're going to take a look at this replacement shock for the Demco Hydraulic Brake Actuators. This part will replace the shock in your Demco Hydraulic Trailer Brake Actuator. It is designed to fit the model numbers DA91, DA10, DA16 and the DA20 models. A few dimensions on this, the overall dimension from one end to the very other end, it's going to be right at 7".
Now when this extends out the full extension measurement will be 9-1/8". Distance from the center of this eye to the center of this eye, right at 6". And the same way if it's extended out it will be 8-1/8". Now the diameter on the smallest eye, which is right down here, is going to be right at 0.625" and on the larger eye is 0.89".But that should do it for the review on the replacement shock for the Demco Hydraulic Brake Actuators.
Order from etrailer allots, never had a problem with wrong parts or functionality
The replacement part I ordered was not in stock, Kellie stated it would not be available to ship until August 7. I was disappointed but could wait, ordered by phone, bid our farewell, that was it. Soon after I received an email from Kelli. She went above and beyond, further researched and located the same item, different part number, from a different manufacturer, had in stock and shipped there same day. Received two days later, compared to original, installed, fits like it was supposed to. Over a three day period I think I talked with all these sales people, Robert, Jerry, Jared, and Kellie regarding different items, they were all very personable, knowledgeable, answered all my concerns, and helped me with the item that best fit my needs, also saving me money. Those Items also arrived two days later in NE OK. The folks a Etrailer are great and would will continue to purchase from them as needed and wildly recommend to others.
Works shockingly well. (see what I did there?)
Awesome ! Fit perfect..ordered 2 replacement actuator shocks for my zieman flatbed trailer nobody had them here in CA..will shop here again soon! Very greatful for my purchase thanks etrailer!
You guys ALWAYS have exactly what I need and your customer service is always top notch. I hate to admit but bought a competitors product because of the price and I should’ve known it was too good to be true! Product didn’t fit. Thank you so much for a great company

Haha! Nice. ^___^ But seriously, I am glad you are liking it, Brett! Hopefully you get to use it a lot this "spring"! (not my best work, but I couldn't help it)
