Backup valve installs in trailer brake actuators with high psi ratings and wires into your tow vehicle so that the trailer brakes do not activate when you shift your tow vehicle into reverse.Products were great. I have one suggestion to the shipping dept. at trailer: DON'T put small items in the same craft paper that is used to fill voids in the shipping box. When I opened my box I pulled out the big bunch of craft paper and set it aside to pitch. I pulled out the bigger brake parts and then realized that i was missing two smaller items. At first I thought maybe they were back ordered. I checked the shipping paper and they were to be in this box. After going thru the craft paper I was going to pitch I found them inside. Close Call!!! Put the small items in a small box or envelope. Thanks. 309406
jeffN - 10/23/2017This was the only item that I bought from you that didn't meet expectations. I was in the process of installing it by hand onto the master cylinder when the front brass fitting broke off. I never even got to tighten it by wrench. I don't know if it was cracked from the start or just poor quality brass, in wither case, it was unusable. The master cylinder and cover are just fine and work perfectly. 134646
This isn't necessarily a product review. It's a simple switch and it solved my problem. But I would rather comment about customer satisfaction. Website was easy to navigate but more so than that was calling the the company. Calls were promptly answered, no question was to stupid and they emailed the answer about the product information in case you didn't make decision right at that point. I have purchased a couple of items from e-trailer and have been very satisfied. If you have a trailer, or any of the many other products they offer, I think you will be happy with choosing this company. I don't usually write reviews, but this few minutes to comment doesn't compare to the time they spent with me to work out a small hiccup I had on my job. Regards, Charlie L. 446665

What a great service etrailer provides. i recently had to place two orders for spare parts. Two different parts suppliers. I placed both orders on a Sunday. etrailer received my order and I had it by Wednesday and had the part installed by Wednesday night. They kept me informed through the whole process via email. My second parts order through a different company had to be canceled and reordered 3 times in 3 days, still don't know where my parts order is. etrailer sets the expectations that others should follow. Great Job. 807740
They don’t seem to last more than a season at best 801000
So far so good. The customer service was excellent. They helped me through the process of product selection with ease and a sense of humor. Much better than the local shops here in Anchorage. I'm not mechanical in any sense so I found the online installation videos to extremely easy to follow. I ended up replacing all the brake lines, the master cylinder and the actuator. It was easy but I did it with help of the videos and a few phone calls to customer service who talked me off the ledge. The calipers will be replaced this year and I'm hoping for similar results. I'll keep you posted and thanks again. Great products, CS and online help. 793307
