We have a couple options for trailer ramps springs. The first one will work great if your ramp rides on a 1-1/2 inch shaft.
For that you would want the Ramp Spring - 2K Torque for 1-1/2" Shaft - RH # RS16933RH or # RS16933LH.
Or we have ramp springs like the Enclosed Trailer Ramp Spring - Dual, 81" Wide # ERS120D81, this spring installs like a garage door spring. There is a lot of tension, so you want to make sure it is installed by someone who knows how to compress these springs and... view full answer...
The Redline Ramp Spring like part # RS16933RH and part # RS16933LH will help with lifting the ramps you said you are building for your trailer. I would recommend 1 spring for each ramp.
These springs are made of steel alloy, these springs provide approximately 90 degrees of deflection and are designed to help lift a ramp with 2,000 pounds of torque. view full answer...
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 enclosed 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 hinge pin and requires... view full answer...
I would recommend you use a Enclosed Trailer Ramp Spring # 362SW61 like you referenced. This kit is close in length to the width of your trailer door and should work well as a ramp assist spring kit.
I've attached a video to assist with the winding of the springs because this system is not the high torque that you need professional assistance to install. view full answer...
For the ramps of your load trail 20 ft trailer we have ramps springs like the part # RS16933RH for the right hand side and the # RS16933LH for the left hand side but your ramps would need to be on a 1-1/2 inch shaft for these to fit.
Check out the review video I attached for these springs for you to check out as well. view full answer...
The heaviest set of springs that I have for ramp doors are the Conventional Ramp Door Spring for 8' Wide Enclosed Trailer part # CB250D96SHD which offers a 250 lb. capacity. This alone will likely not be enough for you.
If in your design you can incorporate something like the Ramp Spring 2K Torque for 1-1/2" Shaft part # RS16933RH for the right and part # RS16933LH for the left it could gie you the lifting support you will need.
If this is not a viable option using a winch mounted in... view full answer...
The best ramp assist spring recommendation I can make for you would be the Enclosed Trailer Ramp Spring # 362SA7. Check out the review video I attached to the right.
The installation instructions for this product are recommended for individuals who have experience winding torsion springs. If you have not worked with a torsion spring system before, we recommend contacting a local garage door company to install this system. view full answer...
For an 8 foot wide trailer you'd want to go with the ramp spring part # CB250D96SHD which is exactly 8 feet wide and will work great with a 7 foot wide ramp door. view full answer...
The springs you mentioned are designed for use on ramps that you'd typically see on a heavy equipment trailer. They're way too stiff to be used on a trailer door.
The correct springs for your application will depend on what you are using the ramp for and the width of the trailer. The Ramp Springs you are asking about are best used for heavyweight steel doors on a horse trailer or for an enclosed car trailer. If one man can lift the ramp, a more lightweight option like a torsion spring... view full answer...
I recommend the Redline Ramp Spring - 2K Torque for 1-1/2" Round Shaft for the new ramps on your trailer. You will need the # RS16933RH for the right and # RS16933LH for the left hand side. One spring per ramp should be adequate without overdoing it. However, you will want to secure the ramps with strap or something similar and not count solely on the springs to keep them in the vertical position. view full answer...
Yes, if you wanted to install the ramp spring part # RS16933RH in the center of a ramp it would work in that orientation.
I attached a picture that shows a ramp with the springs mounted more towards the center. view full answer...
If your 7-foot long and 2 foot wide ramp is heavy enough then you would use ramp springs such as # RS16933LH and # RS16933RH. But each of these springs produces 2,000 foot pounds of torque so they may be way too strong for your ramp. If you can tell me how much the ramp weighs I can determine if these springs would be a good fit.
Based on the material and size I am willing to say the ramp is probably too light for this type of spring. Another option that could work for you is the trailer... view full answer...
Thank you for all of the info you listed for your enclosed trailer ramp. The best option is going to be the ramp spring kit part # ERS120D81. This is 81 inches wide and has capacity of 120 lbs. This is more capacity than you'd need but it can be wound for less lifting capacity like what you'd need so that you can tailor exactly how much lifting capacity you'd need. view full answer...
For enclosed trailer ramp/doors the best option is the style of spring that mounts to the top of the rear door frame and pulls the ramp up like the Enclosed Trailer Ramp Spring # 362SA6. The Gorilla Lift you mentioned only works on utility trailer with raised bed rails. view full answer...
Yes, the Ramp Spring - 2K Torque for 1-1/2" Shaft - RH # RS16933RH would work on the right side of your trailer and the Ramp Spring - 2K Torque for 1-1/2" Shaft - LH # RS16933LH would work for the left hand side of your trailer.
Both of these springs are designed for use on 1-1/2 inch diameter shafts so they would fit very well. I attached a picture we got from a customer who used these springs on an adjustable width ramp just like you plan on doing. view full answer...

For a 200 lb trailer ramp door we have the Conventional Ramp Door Spring part # 362SA8HD which would work great as it has a 230 lb capacity. You'd need to have a professional wind it for you but it would easily work great for a 200 lb trailer ramp door. view full answer...

We don't have the replacement spring, but we do have the Enclosed Trailer Ramp Spring - Dual Spring, 81" Wide # ERS120D81 to replace the entire assembly. This will give you the spring, the drum, the bar, the brackets and the cable. This unit has a spring capacity of 120 lbs. This product is designed with dual cables so in the event that one is accidentally cut, the ramp door will not free fall to the ground. view full answer...
