Review from a similar M-3 Enclosed Trailer Dual Ramp Spring

First off, Deborah was awesome to deal with and had the ramp door spring shipped super fast. Thank you! I had never installed a torsion spring and this one took me two hours, including removal of the old one off a Pace cargo trailer. You might need to cut off part of the tube ends to fit your application. I put a grinding wheel on my skilsaw and chopped off 3 inches from each end. I used my existing mounts on the header and so I removed the ones on the new spring assembly...4 bolts. The mounting plates on the assembly are easy to slide to fit my application. Installation onto the header was very quick and easy. Again, four bolts that are a bit soft and easy to strip...I used my existing hardened bolts that were exact match in every respect...only harder alloy. The cables came next. I suggest using existing hardware if it's in good shape. The provided pins and cotter pin mount left too much slop at the ramp. Good bolts and a good locking nut was what I used and allowed for plenty of relaxed movement without compressing the eye of the cable end. Vise grips come in handy when rolling the cable on the drums as you'll want to keep the bar assembly from moving while loosening the drums to roll up the slack of the cables...tighten the two set bolts on each drum and you're ready to start winding the springs. Make sure the BLACK drum is mounted to your left while looking out from inside the trailer or the entire assembly will need to be flipped. I used some rebar for winding rods and ground them down a touch to fit easily inside the cavities of the spring winder. This worked well for me, but the proper winding rods are no doubt safer and should be used or simply get a professional garage door company to do the winding part and balancing for safety reasons. Once wound according to the instructions, lock the set bolts onto the rod and you can remove the winding rods. I used the top of my trailer to help hold the rod while tightening the set bolts...all the while holding another rod in the cavity for safety. From there, you will want to readjust your drums on the cables to get an equal amount of tension on each cable. One cable will likely be a lot tighter while the other relaxed upon rasing the ramp. With the door up and closed, loosen the drum set bolts on the LOOSE cable drum and spin it to get a tighter cable and lock the bolts back into place. Raise and lower the door a time or two and go back into the trailer with the door closed and readjust the drum that has cable slack until they are fairly equal. That was it and other than the appeals for safety around the entire process, it was easy to do. Unless you are used to working around stuff like this, I think having a garage door company wind the springs and adjust the drums would be money well spent to avoid any potential injuries. I doubt it would cost much because that part goes pretty quickly and they would have the experience to do it in about 15 minutes or so. 128509

Review from a similar M-3 Enclosed Trailer Dual Ramp Spring

Haven't installed it yet, but it appears to be a well made assembly. It will be installed in the next week or so. Delivery was prompt, and package arrived in very good condition. My ramp is quite heavy and the trailer somewhat narrow, so this spring assembly should fill the bill nicely. 146468

Expert Answers about Enclosed Trailer Ramp Spring - Dual, 96" Wide - ERS160D96Do you have a question about this Enclosed Trailer Parts?

  • Choosing/Sizing the Correct Trailer Ramp Spring for a Ramp Door
  • When selecting ramp springs for a trailer ramp, you will want to know the diameter of your hinge pin and how much space you have available in the hinge. A typical horse trailer or utility trailer ramp uses 3/4 inch hinge pins and would require two ramp springs with a 3/4 inch inner diameter. The ramp springs that we carry fit 1-1/2 inch diameter hinge pins and are designed for use with heavy-duty steel ramps like those on equipment trailers or car haulers. The spring slips over the...

  • Recommendation for Enclosed Trailer Ramp Springs for a 7 Foot by 14 Foot Enclosed Trailer
  • The system that will probably work best for you is the Enclosed Trailer Ramp Spring - Dual, 81 Inches Wide, # ERS120D81. I went out to the warehouse and measured the distance between the mounting brackets. It is 64-1/2 inches from bolt hole center on one bracket to bolt hole center on the other bracket. The overall length is 81 inches. Since you have a 7 foot (84 inch) wide trailer, the 81 inch assembly should be a good fit. An assembly that measures 96 inches wide will be too long to...

  • Will Adding Enclosed Trailer Ramp Spring ERS160D96 Double the Lifting Strength of My Trailer Door
  • Adding additional springs like the Enclosed Trailer Ramp Spring, # ERS160D96, will make it much easier to lift the trailer door on your enclosed trailer. However, if you were to add too many springs or too large of a system, the door may not stay down. Also, it is recommended that unless you have experience working with torsion springs, this system should be installed by a professional with torsion spring experience. If you determine that the double spring system is too large, then I...

  • Choosing the Correct Ramp Springs for Enclosed Cargo Trailer
  • The springs you mentioned are designed for use on an existing door hinge that uses a 1-1/2 diameter rod or pipe as a hinge pin. The spring would be slipped over the pipe and there would need to be gaps of at least 2-1/2 inches in the hinge barrel on the door and on the trailer to allow room for the width of the spring. The ramp springs are not designed for lightweight doors that have an aluminum skin and a wood core. The correct springs for your application will depend on what you...

  • Availability of Enclosed Trailer Hinge Ramp Springs
  • I do believe we have the springs that you are looking for, but they are not part of a kit. We have a left, # RS16933LH, and a right, # RS16933RH. These springs are for a 1-1/2 inch diameter shaft. They will need to be welded into place with the two arms facing down and flat against the trailer and door surfaces. Each spring is rated for 2,000 pounds torque to help with lifting and lowering ramp doors on trailers.

  • Overhead Clearance Necessary to Install Enclosed Trailer Ramp Spring # ERS160D96
  • According to our friends at Redneck Trailer Supply, the reel on the end of the Enclosed Trailer Ramp Spring, # ERS160D96 measures 5 inches in diameter, so you would need a bit more than 5 inches of room on the header above the rear door of your snowmobile trailer.

  • Can the 96 Inch Wide Enclosed Trailer Ramp Spring be Trimmed to Fit a 92 Inch Wide Trailer
  • Yes you can cut the shaft on the 96 inch wide ramp spring, # ERS160D96, to fit your 92 inch wide trailer. The shaft is made of steel tubing so the proper saw or power saw blade would cut through it. Be sure to get a straight cut and file down the rough spots. Regarding installation, a professional with experience should install this in your trailer. Torsion springs are under a lot of tension and can be dangerous if you do not have experience with them. A garage door installer would be...

  • Can a Trailer Ramp Door Spring System Be Used on a 12 x 16 Foot Building
  • I do recommend the 96 inch system # ERS160D96. You can trim down the length some on each end for a better fit. The 160 pound capacity though is still under the approximate 200-250 pounds of your door so adding something to supplement this system would be needed to avoid damage to the system. The springs are longer than on the shorter systems, as is the main shaft. The actual product weight is going to be slightly different but the shipping weight is the same. It is also strongly advised...

  • Ramp Door Spring for a Trailer with a 5 Foot Wide Door
  • For a 5 foot wide door you would need to use ramp spring # ERS80S66. It is 66 inches wide so it will need to be trimmed down to fit if the interior of the trailer is not 66 inches or more wide. It can be trimmed down as low as 45 inches. The capacity is 80 pounds though so it will not take the full weight of the door. Even the 96 inch long model, # ERS160D96, can only handle up to 160 pounds and you would not be able to trim it down enough to fit most likely. The installation instructions...

  • Rear Ramp Door on Pace Enclosed Trailer Does Not Open or Close All the Way with Hinge Springs
  • It sounds like there could be something bent either on the ramp itself, the body of the trailer or the spring or hinge pin. You could replace the hinge type springs with an enclosed ramp spring system such as # ERS120D81 at 81 inches wide and 120 pound capacity but if something is bent then it will still have the same issues. We also have the enclosed springs in different sizes: # ERS160D96 is 96 inches wide, 160 pound capacity # ERS80S66 is 66 inches wide, 80 pound capacity # ERS80S96...

  • When Does the Spring Tighten and Loosen on an Enclosed Trailer Ramp Spring
  • On a torsion spring like that on # ERS160D96 when the door is opening downward the line is spooling out and the spring will get tighter. When the line is spooling in, closing the door, the spring will relax or get looser. As such if you have not worked with torsion springs before we strongly recommend having a professional perform the installation. A local over head door company should be able to help.

With your rear ramp door being 66 inches wide, this ramp spring would work for your trailer. The weight capacity is 120 pounds.

This is a 96 inch wide spring with a 160 lb capacity that is wider than the spring you recommended that should better match your door ramp width that should do well for you but it will require you mounting it directly to your trailer and not use the mounting brackets you already have.

  • Trailer Ramp Door Is Hard to Open and Close, Do the Torsion Springs Need to Be Replaced
  • It could be that the springs are worn out and need to be replaced with either new springs or a new system such as # ERS160D96. Inspecting, working on, and/or installing these systems is not something you would want to do yourself because they can be dangerous (the springs are under a lot of tension). I recommend having a garage door company take a look at it to determine if anything can be done to fix the existing system or if a new system is needed.

  • Could # ERS80S66 Ramp Door Spring Be Cut Down for Use on a 5 ft Wide Enclosed Trailer
  • The whole assembly (96 inches wide) would be too long to trim down and still fit. I'd recommend going with a single spring like # ERS80S66, whch can be trimmed down to 45 inches long. The spring has a capacity of 80 lbs. If that's not enough capacity you could use two of them in tandem with one mounted above the other on the door header. We strongly recommend having a professional overhead door technician install the spring for you. The spring needs to be tensioned, and if it lets loose...

  • Will 96 Inch Long Trailer Ramp Spring Work in a 119 Inch Opening
  • The 96 inch long ramp spring # ERS160D96 could work but you would have to use a longer shaft and make the necessary adjustments. This is not something the average person should attempt because torsion springs can be dangerous. We strongly advise professional installation and modification by a qualified garage door company..

  • Can a Pace Trailer Ramp Be Adjusted to Open Easier After the Torsion Ramp Spring Cable Breaks
  • Since your Pace trailer was using an Enclosed Trailer Ramp Spring, like # ERS160D96, if you want the spring to function again you will need to have a qualified professional work on it, one with experience with torsion springs (like a garage door company). Without the cable and spring in good working order, the ramp will never operate as easily as it did before. That is unless you repair the old spring or install a new one. I have included a link to our springs. You may be able to use...
