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!

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.

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.

See what our Experts say about this TRC Trailer Ramp Springs
- 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
view full answer... - Can I Use the Conventional Ramp Door Spring on a Trailer that Doesn't Have a Spring?Yes, it will. You can add the Conventional Ramp Door Spring for 5' Wide Enclosed Trailer item # 362SA5 to your enclosed trailer even though it didn't come with one. This fits a 32" to 56" wide trailer door. It measures 56" wide x 4-7/8" tall x 7-1/2" deep and has a 85 lbs capacity.
view full answer... - Best Ramp Door Spring For 56" Wide Door That Weighs 111 lbsHello Darrin, thanks for reaching out. For your 56" wide door what I recommend is the Conventional Ramp Door Spring # 362SA5. This is made for the 56" wide doors, and the 85 lb capacity will make opening and closing the rood much easier. Just keep in mind these kind of ramp springs require professional installation.
view full answer... - Do You Have a 28" Long Ramp Door Spring? Hey Don. What kind of trailer do you have? We have two types of ramp door springs so I am going to need a bit more information from you. The Replacement Spring Assembly for Buyers Products EZ Gate Tailgate Assist for Open Landscape Trailers item # 3373015510, you were looking at works with a system like item # 3375201000 and mounts on the top of the rails of standard landscaping trailers. The spring measure 28" long and has a 180 lbs capacity. Our only other option is your standard...
view full answer... - 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.
view full answer... - Pictures for Showing How Trailer Ramp Springs Attach to Enclosed TrailersNormally the trailer ramp springs like the # 362SA5 attach to the inside of the top of a trailer door like the picture I attached shows. In the picture you can also see how it attaches to the ramp as well.

- 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...
view full answer... - Would Replacing Ramp Spring of Horse Trailer Make Ramp Feel LighterIf 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.
view full answer... - Length of Cables for Conventional Ramp Door Spring for 5 Foot Wide Enclosed TrailerI 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,...
view full answer... - Replacement Ramp Door Spring Kit for 85 lb Horse Trailer DoorWe 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.
view full answer... - Can TRC Enclosed Trailer Ramp Spring Be Cut DownAn 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.
view full answer... - How Tall Can the Door be With the TRC 362SA5 Ramp SpringWith 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.
view full answer... - Hitch and Ramp Door Spring for Look Element Cargo TrailerTo 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...
view full answer... - Trailer Ramp Spring Recommendation for Enclosed Trailer with 5 foot Wide RampWe have the enclosed trailer ramp spring part # 362SW61 that is 67 inches long which would work well for you and can be shortened to your desired length while retaining the 120 lb capacity. Your other option is to use # 362SA5 which has an 85 lb capacity and is 54 inches wide. This will install above the ramp door opening and the steel cable will help lift the door.
