Video Transcript for Review of M-3 and Associates Enclosed Trailer Parts - Ramp Door Spring - M384FR
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.

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.

The coil spring works great. I saw a ramp door online and copied it for my shed. I built the ramp door from the shed double opening doors and used most of the parts from etrailer.com The dual spring is used to assist opening and closing the ramp door. I calculated the weight and called etrailer.com and they helped me size the dual spring.
by: Sean04/18/2024
After destroying my single door spring I opted for this dual spring setup due to the door always being heavy to raise.
Wow what a difference! 3 turns on each spring and I can easily lift the cargo door with 1 hand (fingers).
etrailer always comes through when you need them. Fast shipping and a great product.
Door spring installed on a Mission 22ft 4 place deck over sled trailer.

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.

The door spring works well. The installation instructions were awful. Fortunately our shop is full of mechanics who could figure it out.

by: Duane 03/12/2024
Works great I did beef up the support and added a center support and bearing. Probably would have been fine as it was but I’m an over do’er.
by: MN Rider06/01/2023
I am happy with door springs and they were easy to install. I installed them on my snowmobile trailer which had a heavy door that I struggled with every time. Now with one hand and little effort the door is easy to close and and open. I would give this a 5 star but the screws holding the pulley tight on the bar keep slipping which means making an adjustments several times a year.

- Are Trailer Ramp Door Torsion Springs Available as Separate ItemsUnfortunately, we don't offer the torsion springs as an individual item. I'd recommend the # M384FR 6-foot spirng assembly which includes the shaft, drums, cable and all the needed hardware for installation. Keep in mind, those torsion springs are wound up with an incredible amount of force so for the sake of safety you'll want a professional to handle the installation for you. I can remember helping a friend to install a similar spring on a garage door years ago. He was using a screwdriver...
view full answer... - Difference Between Conventional Ramp Door Spring for 6' Wide Enclosed Trailer # M364FR and M384FR The Conventional Ramp Door Spring for 6' Wide Enclosed Trailer # M364FR has two spools that cables can attach to which gives a bit more flexibility in how it can be used whereas the # M384FR only has a single spool. I attached review videos for both for you to check out as well.
view full answer... - Replacement Ramp Door Spring Assembly for a Cargo Trailer Ramp Door The spring assemblies are pretty universal and can be cut to length depending on what size you need. The Conventional Ramp Door Spring for 7' Wide Enclosed Trailer - Dual Spring - 120-lb Capacity item # ERS120D81 will work for your Carry-On 6X12CGR7K. You will have to shorten the bar to get it down to the 66" wide you require. If you don't have experience working with torsion springs I recommend you contact a garage door installer. Each spring has to be wound a quarter turn at a time 30-40...
view full answer... - Overhead Ramp Spring for Use with 80 Lb Trailer RampIf the weight you would be lifting is the weight of 80 lbs then yes you'd only need the part # M384FR to help lift it. This would have enough capacity and could be wound to basically make the ramp feel like its very light.

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.
