Hey, Julius. Sorry to hear what's going on. Have you checked and adjusted the tension? If you don't have experience using torsion spring system before, I recommend contacting a local garage door company to look the spring over.

Harder to find parts, convenient and informative website and prompt service.

This made a HUGE difference! Now this single woman can handle this ramp door!

Sweet! Glad to hear that :)



by:

This purchase was definitely worth the money. As a lawn care guy I raise and lower the ramp a lot. This will save ya back for your gf. lol The only reason I didn’t give it 5 stars, one of the cables keeps coming off.. it’s driving me insane! lol Still works with one though.



by:

Excelente servicio. Puntual



by:

Install was easy, works as expected, easy to adjust tension. Installed with a ramp door for our garden shed a year ago. Still happy with it.



by:

Every time I open my trailer ramp door I am so thankful I did this up grade. I had to buy a 36” pice of rebar to wind the spring and experiment with the placement of the brackets that go on the interior of the door. Truly a back saver!



by:

I had my local Trailer shop install the Ramp Door Spring, and it works perfectly. Ramp door can be lifted with with ease. Great Kit.

@John Hey John, really appreciate you coming back with the one year update. That’s awesome to hear it’s still working just as well and saving your back every time you use it. Those ramp springs make a bigger difference than people expect, especially on heavier doors. Sounds like it’s been doing exactly what you needed without any issues, which is always the goal. What are you usually loading on your trailer these days?

  • Recommended Garage Door Spring for a 5' Wide Trailer Door
    Hey Michael! I would be happy to help you with the spring assist but we do not have a ramp door for you. I've got a couple options for springs depending on the weight of the door/ramp you choose to go with. These come with all mounting hardware necessary to get them set up. I have listed them below: 80 lbs Capacity - Conventional Ramp Door Spring item # M384FR 120 lbs Capacity - Conventional Ramp Door Spring item # 362SA6

  • Can You Buy Just Ramp Door Spring Not Entire Assembly For 5' Wide Enclosed Trailer Door?
    We do not sell only the spring. If you're needing a new spring, you'd need the entire assembly # 362SA5 if the 85lb door rating matches the weight of the door. If you have a different door weight, let me know and I can see if we have something that's sized right.

  • Measuring Enclosed Trailer Ramp Door Weight For Torsion Spring Lift Assist
    To determine the correct weight springs you will need a scale to determine how much weight is on the door when it lays out on the ground. You will place the scale on the ground in the center of the landing path of the door edge. This will tell you how much of the door weight is on the ground when fully open. Be sure not to go with a spring that is rated for more weight than your door or you might run into issues of the door trying to close after you lower it. You do not want to use the...

  • Would Replacing Ramp Spring of Horse Trailer Make Ramp Feel Lighter
    If you replaced the springs on your ramp door with the # RS16933RH it would definitely make the door seem lighter. If the shaft diameter that you current spring is installed on is 1-1/2 inch in diameter this would fit and work well. The matching left hand side is # RS16933LH. We also have spring assemblies that mount up high and use a cable and torsion spring to make the lifting easier like with part # 362SA5 which is for 5 foot wide ramps.

  • Length of Cables for Conventional Ramp Door Spring for 5 Foot Wide Enclosed Trailer
    I reached out to the manufacturer, who told me the cable was 135 inches long for the Conventional Ramp Door Spring for 5' Wide Enclosed Trailer # 362SA5. What you will do is measure from the top of your door down to the bottom of the door and if it measures up you can use the spring. In regards to capacity, the 85 lbs is the max weight the door can be to safely use the ramp door spring. If you need more capacity or a longer spring, for a longer 150 inch cable and 120 lb door capacity,...

  • Replacement Ramp Door Spring Kit for 85 lb Horse Trailer Door
    We have both single and dual ramp spring sets and form my understanding it has more to do with the weight capacity than anything else. For your 85 lb ramp we have the Single Spring # 362SA5 that fits a 5' wide enclosed trailer. Aside from that I recommend choosing your door width and then a spring weight rating similar to how heavy a door you have from our linked selection.

  • How Tall Can the Door be With the TRC 362SA5 Ramp Spring
    With the cable of the TRC Ramp Spring # 362SA5 being 135 inches long, using the form to get the measurements of a right triangle, a^2+b^2=c^2, you will get 67 1/2 inches. This will therein allow for a door that is just over 5 1/2 feet.

  • Can TRC Enclosed Trailer Ramp Spring Be Cut Down
    An Enclosed Trailer Ramp Spring, like part # 362SA4, can be cut down to fit 23-3/4" to 43-3/8" doors. Ramp Spring # 362SA5 can fit 31-5/8" to 55-1/2" inch doors. They are customizable to fit the space available in your trailer as well as the door size so for your door I recommend # 362SA5. These springs are unique in that they are not the high torsion springs that require professional assistance for installation. They are self adjusting.

  • Hitch and Ramp Door Spring for Look Element Cargo Trailer
    To install a hitch, you'll want to go with an adjustable width RV hitch, the correct part will depend on how far apart your frame members are. • For an 18-51 inch frame spread, use # C13701 • For a 22-66 inch spread, use # C13704 From what I saw on the manufacturer's website, it looks like your trailer has a ramp door. We don't offer a shock absorber-type system for that, typically a garage door style torsion spring is used. The exact setup needed will depend on the inside width of the...
