Jeff: Hello everybody. This is Jeff at etrailer.com. Today, we're going to take a look at this conventional single spring, single drum ramp door spring for up to a six foot wide, enclosed trailer, has an 80 pound spring capacity. Now this part will replace your old trailer door spring with this nice heavy duty conventional ramp door spring. This ramp door spring will let you easily lift and lower the door on your enclosed trailer without risk of injury. It is designed to help take on the weight of the trailer door so that you don't have to.
This one here happens to be a single spring and a single drum system. A single spring is on the torsion rod has this cable drum here with the lift cable at the one end to lift the door. It only uses one cable to lift the door in this application. And this system is normally used in snowmobile trailers to help reduce the potential for catching a ski in the cable.This spring does reduce the wear helps prevent damage to the door hinges. Now, when you do install this, the spring is designed to be mounted one way for proper operation.
And the way you can tell that is if you look at the cable drum, it'll be stamped with an R, which means for the right side. And they do also spray painted black here for visual indication of knowing that that's for the right side. The right side is designed to mount on the curb side of the trailer.Now this part will include everything laid out here on the table. The spring itself, the mounting brackets, the hardware for the mounting brackets, the bearing, gives you 150 inches of one eighth inch diameter cable and hardware to install that. And then the set screw cover.
Now this spring system can be modified to fit your specific application.You can slide the bearing and the mounting bracket where needed, and then just cut the shaft to a shorter length. So if we put the bearing on, let's say, you're going to go all the way, to narrow as possible. And if you put the mounting bracket on. So you can see what that all installed, it will fit any words from if we measure this portion 34 and three quarter inch wide trailer door, all the way up to the widest, which would be sixty six and seven eighths inches wide. Now this is a nice sturdy steel construction.
It is made in the USA. Few specs, again. The overall length from this end, all the way to this end is going to be right at sixty six and seven-eighths inches long. The drum diameter, which is the widest diameter on this is about four and three quarter inches diameter. And the spring capacity, as we mentioned, is 80 pounds.But that should do it for the review on this conventional single spring, single drum ramp door spring for up to a six foot wide enclosed trailer, has an 80 pound spring capacity.

Ratings & Reviews
It has been one year since I purchased and installed this product and it has been working great since then. As well, the shipping was prompt.
I bought this to retrofit an enclosed trailer that was originally built with exterior springs.
This is a major improvement over the other style and money well spent. Everything went smoothly according to the instructions. I was good at 38.
My door is now a "one hand wonder".
It would not fit my type of trailer , I tried to explain this prior to ordering but no one would listen.
Mr Doug Wait the owner of the company got involved after I couldn’t make it work, he was awesome and very straight forward , about the installation. I would never hesitate to buy
His products if they were adaptable to my install!
Received it in a timely manner following the instructions it was very easy to install by myself very happy with the way it's operating
Great spring for my 4 ft door on a small mc trlr! It arrived w a damaged roller n you quickly sent a replacement! I had a friend who installs garage doors to install it for me and it works perfectly! Thank you! The door was getting a little too heavy for me to safely lift.
Because it's taking 3 times to get my order things where missing the first shipment then the second shipment didn't have all of it now the other thing is on back order not pleased with this company
Worked well on my trailer
It's perfect! I found it easy to install with the right tools and instructions, and it works very well. My first order was damaged or lost in shipping, but Paula took care of it and sent me a replacement. I'm very happy with my purchase and their service.
When the part arrived we noticed that one of the parts was broken. My wife looked at our ring camera and noticed the delivery driver threw the box on our porch carelessly.
I installed the spring kit this PM. Works great! I extended one bracket to make it work (welded a flat on the mount side). I set the spring at 8 turns and backed it off 1/2 turn to get the assist I wanted. Easy peasy!

This spring does fit on the passenger side of the trailer if you were facing the back of the trailer. All of our single, conventional springs would be the same. We also carry dual springs that would install on both sides.

I replace the door spring on my trailer with this product, everything fit properly and hopefully it will last a long time. I tried finding some one to installed the door spring, but no one wanted to do it. I ended up doing it my self, after watching a few videos on line.
Do you have a question about this Trailer Ramp Spring?
